Having recently arrived in Spain, I’m currently looking at properties and hoping to get on the property ladder. I’ve found that the houses here, especially in the old towns, have a lot of charm, but I can’t help but feel anxious about potentially buying an unsafe property with structural problems. Real estate agents might paint a rosy picture, but you need to be able to judge for yourself, right? After some research and consulting with local friends, I’ve compiled a few tips for assessing a property’s structure during viewings. I’m sharing them here, hoping to help others on their home-buying journey.
1. Start with the “Big Picture”: Foundation and Exterior Structure
When viewing a property, don’t just rush inside to look at the interior design. First, walk around the outside of the building. This is the absolute basic. Pay close attention to:
- Around the Foundation: Check the lower part of the exterior walls for any significant, continuous cracks, especially those extending upwards at a 45-degree angle. This could be a sign of uneven foundation settlement, which is a major problem!
- Exterior Wall Flatness: Step back a bit and visually “draw” a horizontal line to see if there are any noticeable bulges or depressions in the wall. Minor unevenness might just be a plastering issue, but if the entire wall looks wavy, you should be cautious, as it could relate to the property structure.
- Drainage System: Inspect the roof’s drainpipes and the ground-level drains to ensure they are intact, with no signs of blockage or water leakage. Water is a building’s number one enemy, and long-term seepage can cause significant damage to the foundation and walls.

2. Look “Inside”: Walls, Floors, and Beams
Once inside, the focus shifts to the load-bearing structures. A newly renovated house might conceal many problems, so you need to be extra thorough.
- Corners and Door/Window Frames: These are areas where stress concentrates, making them prone to cracks. If you notice that doors don’t close properly, or if there are wide gaps or even deformation between the frames and the walls, it could indicate that the structure has shifted.
- Ceilings and Floors: Are there any water stains on the ceiling? Pay special attention to the top floor and the area below bathrooms. Water stains don’t just indicate a leak; they can be a sign that the floor structure has been eroded over time. Walk around on the floor and feel for any noticeable vibrations or creaking sounds, especially in older houses with wooden floors.
- Load-Bearing Beams: Many old houses have exposed wooden beams, which provides a great opportunity for inspection. Check the beams for any signs of insect damage (small holes), rot (blackened areas), or cracks. You can tap them with a hard object like a key to listen for a solid sound. If they are concrete beams, look for cracks or exposed, rusted rebar.
3. The Ultimate Tool: The ITE / IEE Report
If you’re interested in an older building, you must ask the seller or agent for the Inspección Técnica de Edificios (ITE) or the newer Informe de Evaluación de Edificios (IEE) report. This is essentially the building’s ‘health check report,’ issued by a professional architect or technician. It assesses the building’s structural safety, sanitation, accessibility, and energy efficiency. This report will clearly state whether the building has any structural problems and if repairs are required.
| Report Outcome | Meaning | What to Note |
| FAVORABLE | Favorable | This means that at the time of inspection, the building was in good condition with no significant short-term risks. |
| DESFAVORABLE | Unfavorable | A major red flag |

If the seller cannot provide this report, or if the result is DESFAVORABLE, you need to be extremely cautious. While it can be used as a bargaining chip to lower the price, you must also evaluate the potential repair costs and risks. In conclusion, buying a home is a major decision, especially in a country you’re not yet familiar with. Do your homework, learn as much as you can, and when it counts, spending a little extra to have a professional architect accompany you on a viewing is a worthwhile investment. I hope everyone finds their dream home—one that is both beautiful and safe!
