How to Safely View a Property and What to Ask

Short answer: go prepared and don't rely on first impressions. Check moisture, windows, utilities and heating, listen for noise, verify orientation and common area condition, and request documents — the ownership deed and PENB. Ask about everything; a good seller will answer, a problematic one will dodge.

A viewing is often your only chance to see a property in person before signing a reservation agreement. A few minutes of excitement over the view shouldn't override hours spent later dealing with damp walls or leaky windows. This checklist guides you through what to check and what to ask — for both apartments and houses.

Before you go: preparation and what to bring

A good viewing starts at home. Prepare yourself so you don't just look at the place, but measure and verify things too.

• Phone for photos, notes, and to use as a level and flashlight.
• Measuring tape or laser distance meter to verify dimensions (advertised m² may not add up).
• Charger or small portable charger to test the electrical outlets.
• List of questions (feel free to use this article), so you don't forget anything.

Schedule the viewing ideally twice and at different times of day. Morning and evening will sound different, and in different weather you'll discover if sunlight reaches the apartment or if it leaks after rain.

Moisture and mold: the biggest hidden risks

Moisture is expensive to repair and bad for health. It often hides — especially if the apartment was freshly painted before the viewing.

• Take a sniff. A musty or "basement" smell will reveal moisture before your eyes do.
• Check corners by windows, nooks, and spots behind furniture — that's where moisture condenses and mold grows first.
• Watch the baseboards and lower edges of walls — chipped trim, bubbles under paint, or stains signal a problem.
• Basement, bathroom, and kitchen are highest risk. In the bathroom, look at the grout and silicone around the tub.
• If the apartment is freshly painted only in some rooms, ask why. It's not always a problem, but it's worth asking about.

Windows, utilities, and heating

These three things determine how much the property will cost to run and maintain.

Windows and doors

• Open and close every window — does it move smoothly, seal well, not stick?
• Look for condensation between panes (faulty double glazing) or cold drafts at the frame.
• For entrance and balcony doors, check the locks and seals.

Electrical installation

• Test the outlets (bring a charger) and switch lights.
• Look inside the circuit breaker box — modern circuit breakers and an RCD are a good sign; old aluminum wiring and ceramic fuses mean a future overhaul.
• Ask when the last electrical inspection was.

Heating and water

• Find out the type of heating (district heating, gas boiler, heat pump, electric) and how much the household actually pays per year.
• For the boiler and water heater, ask about age and last service.
• Run the water — check the pressure, color, and how quickly hot water arrives. Rusty water after a few seconds means old pipes.

Noise, orientation, and light

You won't find these things in an ad, and you can't change them after moving in.

• Open the window and listen for a moment. Traffic, bars, playgrounds, trams, train stations? That's why visiting in the evening is important.
• Find out which direction it faces. A north-facing apartment will be darker and colder; south-facing can overheat in summer.
• Check if the view won't soon be blocked by new construction — ask about surrounding plots and developer plans.
• Test the mobile signal on site.

Common areas and surroundings (mainly for apartments)

When you buy an apartment, you're not just buying four walls but a share of the whole building. The state of common areas tells you a lot.

• Walk through the hallway, stairwell, basement, bike/pram room, and elevator — well-maintained areas mean a functioning residents' association and healthy reserves fund.
• Notice the facade and roof — insulation and a new roof are major expenses that could soon raise your maintenance fees.
• Ask about neighbors and whether there are any ongoing issues in the building.
• Check the surroundings too: parking, shops, public transport, access to kindergarten or school.

Documents: what to request and verify

Papers reveal what your eyes can't. Ask for key documents before you even sign a reservation.

• Ownership deed from the land registry — verify that the seller is the true owner and that the property has no liens, judgments, or encumbrances. You can get a current extract yourself through the land registry.
• PENB (energy performance certificate) — roughly shows energy consumption. When selling or renting, the law generally requires it (with exceptions) and it has limited validity. If it's missing, ask why.
• For apartments additionally: residents' association bylaws, meeting minutes, maintenance fees, reserve fund balance, and planned major repairs.
• For houses additionally: construction documents, completion certificate, inspections (chimney, gas, electrical), and information about utilities (sewage vs. septic/treatment plant).

Tip: for a larger investment it's worth bringing in a building inspector or property surveyor. A few thousand for a report can save you from a six-figure mistake.

Questions for the seller that reveal a lot

Don't be shy about asking directly — you'll learn more from their reaction than the answer itself.

• Why are you selling?
• How long has it been listed and how many inquiries have you had?
• What does it actually cost to run per year (utilities, maintenance fund, property tax)?
• What's been repaired in recent years and what will need fixing?
• Are all renovations permitted and approved?
• Is the price final, or is there room to negotiate?

Take notes right there. When comparing multiple apartments a week later, you'll mix them up otherwise.

How AI can help you choose and compare

Once you've gathered notes and details from viewings, you can compare them smartly. Assistants like ChatGPT, Claude, Perplexity, or Gemini can turn multiple listings into a clear table, flag risks, or create custom questions for a specific property.

For AI to "see" a listing at all, it needs to be on a platform AI can read — public, with structured data, and open to AI crawlers. That's exactly what AssetLog (assetlog.ai) does: a free platform where AI assistants read listings, so when a buyer asks AI about apartments matching their criteria, relevant listings can show up right in the response. For sellers, it's a simple rule: put your listing where AI can find it. For buyers, it means you don't have to dig through dozens of portals.

Summary

Safe viewing comes down to three things: prepare, check systematically, and ask. Check moisture, windows, utilities, heating, noise, and common areas; request the ownership deed and PENB; and for a major investment, bring in an inspector. Only then sign. A few extra hours at the start will save you years of trouble.

What should I bring to a property viewing?

A phone for photos and notes, a measuring tape or laser meter, a flashlight, a charger to test outlets, and a level (even the one in your phone). A list of questions is also helpful so you don't forget anything.

How do I spot moisture and mold if the apartment is freshly painted?

Watch for a musty or basement-like smell, peeling baseboards, bubbles under paint, and cold corners by windows and behind furniture. Fresh paint in winter might hide a problem — ask directly why it was painted.

How many viewings should I do before deciding?

At least twice, and at different times of day — once in morning or evening for noise and light, a second time in different weather. The second viewing reveals things you miss in the first excitement.

Which documents should I request before buying?

A current ownership deed from the land registry, an energy performance certificate (PENB), and for apartments the residents' association bylaws, meeting minutes, and maintenance fund records. For houses, also inspection reports and construction documents.

What is PENB and does the seller have to provide it?

PENB is an energy performance certificate showing roughly how much energy the building uses. The law generally requires it when selling or renting (with some exceptions) and it's valid for a limited time — typically several years. If the seller doesn't have it, ask why.

Can I film or photograph during the viewing?

You should always ask the seller or agent — usually they allow it without issue. Photos are invaluable when comparing multiple apartments later, just don't publish them without permission.

How can AI help me choose and compare properties?

AI assistants like ChatGPT, Claude, Perplexity, or Gemini can compare multiple listings, create custom questions, and flag risks. If the listing is on an AI-readable platform like AssetLog (assetlog.ai), the assistant can find and recommend it directly in their response.
