Hey everyone, welcome back to My Weird Prompts. I am Corn, and I am sitting here in our living room in Jerusalem with my brother, looking out at a very rare clear blue sky. It is Tuesday, February third, twenty twenty-six, and for once, the winter rain has given us a breather.
And I am Herman Poppleberry. It is a beautiful day, Corn, though if you listen closely, you can hear the hum of the light rail testing over on the Green Line. They actually started the round-the-clock system tests between Turim and Malha just a few weeks ago. It is a sign of progress, but I think our housemate Daniel might be feeling a little less serene about the city's progress than we are. He sent us a prompt that really hits home for anyone living in this city, or really any city where the housing market feels like a high-stakes competitive sport.
Yeah, Daniel has had a rough run with rentals lately. We have lived through some of those sagas with him—the leaks, the unresponsive landlords, the literal removal of bathroom fixtures by a disgruntled owner. It is enough to make anyone want to just buy a place and take control of their own destiny. But as he is finding out, buying in an ancient city like this is like navigating a minefield with a blindfold on.
It is the classic dream of the fixer-upper. You find an old building with character, something with history, and you breathe new life into it. But as Daniel pointed out, his wife is the architect, so she has the professional eye for the vision, while he is looking for a way to contribute to that initial triage when they are walking through a potential property. He wants to be the first line of defense against a bad investment.
Exactly. He wants to know how to spot the good stuff and avoid the money pits, especially when it comes to structural integrity and that nightmare of moving into a neighborhood only to have a jackhammer start outside your window at seven in the morning for the next three years. And in twenty twenty-six Jerusalem, with the Blue Line digging tunnels under King George Street, that is a very real fear.
That is a very real fear, especially here. So, today we are going to dive into the art of the property walkthrough. We will look at what good bones actually means from a technical perspective, how to spot the red flags that even a fresh coat of paint cannot hide, and how to do some detective work on the neighborhood's future construction plans using the latest municipal tools.
I think a good place to start, Herman, is that phrase good bones. It gets thrown around by real estate agents all the time. It sounds sturdy and reassuring, but what are we actually looking for? If I am walking into a seventy-year-old stone building in Jerusalem or a century-old townhouse anywhere else, what constitutes a healthy skeleton?
It is a great question because people often confuse a lack of modern finishes with bad bones. Good bones refers to the primary load-bearing structure of the building. In older buildings, you are often looking at thick masonry walls. In Jerusalem, that usually means solid stone or, in buildings from the nineteen fifties and sixties, a reinforced concrete frame with stone cladding. You want to look at the foundation and the vertical supports first.
So, when we are walking through, we should be looking past the peeling wallpaper and the ancient linoleum. What are the signs that the actual frame is failing? Is it just about the cracks?
Cracks are the language of the building, but you have to know how to translate them. Every old building has some settling cracks. Those are usually thin, hairline fractures where the plaster has dried out or the building has shifted a millimeter over fifty years. Those are usually fine. What Daniel should be looking for are wide cracks, anything wider than a pencil, especially if they run diagonally or if they are wider at the top than the bottom.
Right, because a diagonal crack suggests that one part of the building is sinking faster than the rest. That is differential settlement, right?
Exactly. It means the ground underneath is shifting or the foundation has failed in one specific spot. In Jerusalem, this can happen because of the varied topography or even ancient cisterns buried under the foundation that finally gave way. That is a massive red flag because fixing a foundation can cost more than the house itself. Another thing to look for is the level of the floors. If you feel like you are walking slightly uphill or downhill in the hallway, or if you bring a small ball and it rolls to one corner of the room, you have a structural tilt.
I have seen people do the marble test in old apartments. It feels a bit like a movie trope, but I guess physics does not lie. What about the walls themselves? In these older Jerusalem buildings, we have these incredibly thick stone walls. They seem indestructible, but I imagine they have their own set of issues, especially with the different types of stone used.
They do. Those thick stone walls are great for thermal mass—they keep the place cool in summer and warm in winter—but they are often held together by lime mortar that can degrade over a century. You want to look for bulging. If a stone wall looks like it is slightly pregnant, like it is bowing outward, that means the internal core of the wall might be collapsing or the outer skin is separating. That is a very expensive fix because you might have to dismantle and rebuild sections of the masonry. You also want to check the pointing, which is the mortar between the stones on the exterior. If it is crumbling, water is getting in, and in our winters, that water freezes and expands, slowly popping the stones out of place.
That sounds terrifying for a budget. Let's talk about the stuff hidden inside the bones, the plumbing and the electrical systems. Daniel mentioned his wife can handle the architectural side, but for a layman, what are the signs that the guts of the building are rotting? Especially in twenty twenty-six, where we all want high-speed fiber and smart home systems.
This is where most people get burned. They see a beautiful old room and think they just need to change the light fixtures. But if the building is fifty or sixty years old, the electrical wiring might be insulated with cloth or old rubber that has become brittle. One thing Daniel can do is look at the main electrical panel. If it still has old-fashioned screw-in fuses rather than modern circuit breakers, or if the panel looks like a bird's nest of tangled wires, you are looking at a full rewire. And in twenty twenty-six, you really want to check if the building has been retrofitted for fiber optics. If it hasn't, running those lines through forty-centimeter stone walls is a nightmare.
And a full rewire means cutting channels into those thick stone walls we just talked about, which is incredibly labor-intensive and messy. It is not just a weekend project.
Exactly. It is not just the cost of the wire; it is the cost of the masonry work to hide it again. Same goes for plumbing. In older buildings here, we often have galvanized steel pipes. Over time, those pipes rust from the inside out. The water pressure gets lower and lower until one day the pipe just bursts. Daniel should turn on the faucets in the kitchen and the bathroom at the same time. If the flow drops to a trickle, those pipes are likely choked with rust. Also, look at the color of the water when you first turn it on. If it is brown or orange for a few seconds, that is iron oxide—rust—coming directly from your pipes.
That is a great practical tip. Check the pressure under load and the color for rust. What about dampness? That seems to be the number one complaint in Jerusalem rentals, and I am sure it is a major concern when buying an older property. How do you distinguish between a little bit of condensation and a systemic rising damp problem?
This is a huge one. Rising damp is when moisture from the ground is pulled up through the porous stones or bricks via capillary action. You will see it as a tide mark on the lower part of the walls, usually up to about a meter high. The paint will be bubbling, and there might be a white, salty crust on the stone called efflorescence. If you see that on the ground floor, it means the damp-proof course, which is a layer of waterproof material in the foundation, has failed or never existed. In Jerusalem, many older buildings never had one.
And if it is on an upper floor? We see that a lot too.
Then it is likely a leak from a neighbor or a failure in the external stone cladding. In Jerusalem, we have this beautiful stone on the outside of every building, but if the pointing has cracked, rain gets driven into the wall. It can take months for that moisture to travel all the way through a forty-centimeter stone wall, but once it starts, it is very hard to stop without major external work. Daniel should look for those telltale yellow rings on the ceiling, which indicate a slow, persistent leak from the apartment above.
He should also use his nose, right? You always say the nose is a structural tool.
Absolutely. Our sense of smell is one of the best tools for evaluating a building. If a place smells musty or earthy, there is hidden mold somewhere. Even if the walls look freshly painted, that smell is a giveaway that the owner might be trying to mask a damp problem for the sale. In twenty twenty-six, some sellers even use ozone generators to temporarily kill the smell before an open house, so if the air smells suspiciously clinical or like a hospital, be wary.
That is a sneaky one. I have heard of people painting over mold right before an open house. It looks great for a week, and then the spores start coming back through the new paint a month after you move in.
It happens more often than you would think. Another thing to check regarding the bones is the windows and doors. Try opening and closing every single one. If a door sticks or if a window frame is warped and won't shut properly, it could be a sign that the building frame has shifted and the openings are no longer square. Also, check the glass. If it is single-pane, you are going to spend a fortune on heating. In twenty twenty-six, double or even triple glazing is the standard for comfort.
Okay, so we have covered the physical structure of the apartment itself. But Daniel raised another point that I think is even more stressful for people in our city: the neighborhood. He wants to avoid buying a beautiful home only to find out he is living in a construction zone.
This is the Jerusalem lottery, Corn. With the urban renewal projects like the Shaked Plan—which has largely replaced the old Tama thirty-eight regulations—almost every older building is a candidate for being demolished or having three new floors added to the top. The Shaked Plan is the new reality in twenty twenty-six, and it allows for even more density than the old rules did.
For those who don't know, the Shaked Plan is the national alternative to Tama thirty-eight. It gives local municipalities more power to approve projects that strengthen buildings against earthquakes while adding significant new square footage. It sounds good in theory, but for the residents, it means living in a construction site for two years or more.
Or longer. And Pinui Binui is even more extreme, where they tear down an entire block and build high-rises. If Daniel wants to avoid this, he needs to do some serious detective work before he signs anything. The first step is looking for those yellow signs from the municipality, but you have to be more thorough than that now.
What are the next steps? I mean, beyond just reading the signs on the street.
He needs to use the municipal GIS map—the Geographic Information System. In twenty twenty-six, the Jerusalem GIS is incredibly detailed. You can look up any specific plot of land and see every active permit, every pending application, and even the master plans for the entire neighborhood. Daniel should look for blue lines on the map. A blue line indicates a new local plan that has been submitted. If he sees a blue line around the building next door, he needs to assume a crane is coming.
So he is looking for anything that changes the zoning or the density. If he sees a plan to turn a two-story house across the street into an eight-story apartment building, he knows his view and his peace and quiet are on a countdown.
Exactly. And he should also look at the age and condition of the neighboring buildings. If he is looking at a beautiful old house, but it is surrounded by crumbling four-story blocks from the nineteen fifties, those blocks are prime targets for the Shaked Plan. It is almost inevitable that they will be redeveloped in the next decade. You aren't just buying the house; you are buying the neighborhood's current state of decay or development.
What about the light rail? We mentioned the Green Line testing, but the Blue Line is the big one for the city center right now.
The Blue Line is massive. It is going to connect Ramot in the north to Gilo in the south, and a huge chunk of it is being tunneled underground right now. If Daniel is looking at a property near King George Street or Emek Refaim, he needs to check the tunnel alignment. Even if the construction is underground, the staging areas for the tunnel boring machines are huge, noisy, and can stay in place for five years. The city's light rail master plan is all online, and it is updated monthly.
I wonder if there is a way to tell just by looking at the neighbors' balconies. You know how people here love to close in their balconies or add little pergolas?
You can tell a lot about the building's management by looking at the common areas. This is the Common Area Audit. If the stairwell is clean, the mailboxes aren't broken, and the garden is somewhat maintained, it means the neighbors actually communicate and have a functioning house committee, or Va'ad Bayit. If the building is a mess, doing a renovation becomes ten times harder because you will need their permission for things like placing a dumpster or running new pipes through common areas.
Oh, that is a huge practical hurdle. If you have a neighbor who hates noise and you are planning a six-month renovation, they can make your life a living hell with complaints to the city.
They really can. I always suggest that people knock on a few doors in the building before they buy. Just say, hey, I am thinking of buying apartment four, what is it like living here? People love to complain. If there is a dispute with a developer or a neighbor who plays drums at midnight, they will tell you. Also, ask about the Tabu—the land registry. In older Jerusalem buildings, sometimes the ownership is a mess, with apartments not properly registered or common areas being illegally claimed by one neighbor. That can kill a mortgage application instantly.
That is the best kind of data, the kind you can't find on a GIS map. So, we have the structural bones, the systems, and the neighborhood context. Let's talk about the renovation itself. Daniel mentioned his wife is an architect, which is a massive advantage. But for the budget, what are the things that people consistently underestimate when they see a place with good bones?
The biggest bombshell in twenty twenty-six is the Heitel Hashbacha, or the Improvement Levy. This is a municipal tax that is triggered when a planning decision increases the value of your property. If Daniel buys a place and then the city approves a plan that allows him to add a room or a balcony, he owes the city fifty percent of that value increase—even if he hasn't built it yet!
Wait, fifty percent? That is half the value of the potential improvement?
Yes. It is calculated by a municipal appraiser. If the new building rights add five hundred thousand shekels to the property's value, Daniel could be hit with a two hundred and fifty thousand shekel tax bill just for the privilege of having those rights. Many buyers don't realize this until they go to register the sale and the city blocks it until the levy is paid. He needs to check the Heitel Hashbacha status of any property before he makes an offer.
That is a massive budget item. What about the physical renovation? We talked about leveling floors earlier.
Right. In old buildings, after you rip out the old tiles, you often find that the subfloor is just sand or rubble, and it is completely uneven. To lay modern large-format tiles, you need a perfectly level surface, which means pouring a new screed across the whole apartment. That is thousands of shekels before you even buy a single tile. And then there is the Mamad, the reinforced security room.
In Israel, if you do a major renovation that increases the floor area, you are often legally required to add a security room if the building doesn't have one.
That is a massive budget item. It involves pouring massive amounts of concrete, often from the ground up through all the floors. If Daniel is looking at an older building without Mamads, he needs to check if the renovation he is planning will trigger that requirement. It can easily add two hundred thousand shekels to a project. However, under the Shaked Plan, there are sometimes exemptions or streamlined ways to add them, but it is still a huge expense.
What about the windows? People love those old wooden frames, but they are usually terrible for insulation.
They are beautiful but practically useless in a modern context. Replacing windows in a stone building is tricky because the openings are often not standard sizes. You end up having to order custom aluminum or high-quality wood frames with double glazing. If you have ten windows in an apartment, that is a very significant expense.
So, if Daniel is walking through, he should be counting the windows and checking their condition. What about the layout? People often want to open up old apartments to create that modern open-plan feel. Is it easy to tell which walls are load-bearing just by looking?
Not always, especially in stone buildings where almost every wall feels thick. But generally, if a wall is more than twenty centimeters thick, it is likely structural. In older concrete frame buildings, you look for the columns. If you see a square bump in the corner of a room or along a wall, that is a concrete pillar. You can usually remove the thin walls between those pillars, but you can't touch the pillars themselves. This is where having an architect wife is a superpower. She can see the potential for a new floor plan where a layman just sees a series of small, dark rooms.
But even with an architect, you have to be careful about the wet zones. Moving a kitchen or a bathroom to the other side of an apartment is incredibly expensive because you have to maintain a slope for the sewage pipes. In an apartment building, you are limited by where the main vertical sewage stack is. You can't just put a toilet anywhere you want without raising the floors significantly to hide the pipes.
Exactly. And in twenty twenty-six, many people want to install mini-VRF air conditioning systems. These are great, but they require significant space for the indoor units and the ductwork. If the ceilings aren't high enough, you end up with dropped ceilings that make the apartment feel like a basement. If I see a place with three-meter ceilings, I see a lot of flexibility for modern systems. If it is two-point-five meters, you are going to have a hard time hiding the guts of a modern home.
Let's pivot back to the construction noise issue for a second. Daniel mentioned he lived next to a project that went on for two years with no end in sight. Is there a way to tell if a building is finished or if they are just on a very long break?
That is a tough one. Sometimes projects stall because the developer went bankrupt or there is a legal dispute. If you see a building with scaffolding but no workers for weeks, that is a bad sign. You can check the building permit at the site entrance. It should have an expiration date. If the date has passed, it means they are in some kind of administrative limbo. Also, look at the crane. If there is a tower crane on the street, that project is in its most intensive phase. If the crane is gone and they are doing interior work, the worst of the noise might be over.
And don't forget the second-order effects of construction. It is not just the noise; it is the dust and the pests. When you dig up an old street for a new light rail line or a Shaked Plan project, you disturb all the nests of things that live underground. We have seen this in our neighborhood, haven't we?
Oh man, the rats and the cockroaches. Every time they start a new project on our block, it is like a mass migration of everything we don't want in our house. It is a real factor. If you are moving into a neighborhood with five active construction sites, you are going to be fighting a constant battle with dust on your balcony and unwanted guests in your kitchen.
So, for Daniel's six-step walkthrough checklist, what would we put on it? I'll start with number one: The Smell and Sight Test. Use your nose for mold and your eyes for wide diagonal cracks or bubbling paint at the base of the walls.
Number two: The Utility Stress Test. Turn on all the taps at once to check water pressure and look at the electrical panel for old fuses or messy wiring. Check if fiber optic lines have been brought into the building.
Number three: The Window and Door Operation. Open and close everything. If it sticks, the building has shifted. It also tells you about the quality of the existing insulation.
Number four: The Neighborhood Reconnaissance. Look for yellow planning signs. Check the municipality's GIS map for blue lines and pending permits. Specifically, check the alignment of the Blue Line light rail if you are in the city center.
Number five: The Common Area Audit. Check the stairwell, the roof, and the garden. If the building's common areas are neglected, your renovation will be a nightmare of neighborly disputes and logistical hurdles. And check the Tabu status.
And number six: The Financial Bombshell Check. Ask about the Heitel Hashbacha. Don't get caught with a two hundred thousand shekel tax bill on the day you try to close the deal. And of course, the Architect's Veto. If Daniel's wife says the structural changes are impossible, he should listen to her.
That is the most important one. Don't fall in love with a view or a floor tile if the professional tells you the foundation is a mess. It is so easy to get emotionally attached to a place during a walkthrough, especially when you are desperate to leave a bad rental situation.
That desperation is the biggest danger. It makes you overlook red flags because you just want the search to be over. You have to be willing to walk away from a hundred places to find the one that is actually a sound investment. Buying a home is emotional, but the technical evaluation is what keeps that emotion from turning into regret.
I think about some of the older buildings we have seen in the Old City or in areas like Nachlaot. Those places have survived for hundreds of years. They have survived earthquakes, wars, and decades of neglect. There is something incredibly inspiring about that kind of durability.
It is amazing. Those Ottoman-era buildings with their cross-vaulted ceilings are structurally incredible. The arches distribute the weight so efficiently that they don't even need modern reinforcements in many cases. But even there, you have to be careful. People in the nineteen fifties often added bathrooms or kitchens by just hacking into those ancient arches, which can weaken the whole structure. You have to peel back the layers to see what is actually holding the thing up.
It is like a layer cake of history and bad DIY decisions. Well, I think we've given Daniel plenty to think about for his next tour. This has been a great deep dive into the guts of the city.
I enjoyed it. It is always good to talk about the things that are literally all around us but that we often take for granted. I hope this helps Daniel and his wife find a place with truly good bones.
Before we wrap up, I want to say a huge thank you to Daniel for sending this in. It is a topic that I know resonates with so many of our listeners who are trying to find their own little piece of stability in a pretty chaotic world.
