How to Safely View a Property and What to Ask

Interested in a property? Go prepared and don't rely on first impressions. Check moisture, windows, utilities, and heating, listen for noise, verify orientation and the condition of common areas, and request documents — ownership certificate and PENB. Ask about everything that comes to mind. A good seller will answer; a problematic one will dodge.

A viewing is often your only chance to examine the property closely before signing a reservation agreement. A few minutes of excitement over the view shouldn't drown out hours later spent dealing with damp walls or leaky windows. This checklist will guide 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 around, but actually measure and verify.

• Your phone for photos, notes, and to use as a level and flashlight.
• A meter or laser rangefinder to verify dimensions (advertised m² may not be accurate).
• A small charger for an outlet to test the electrical system.
• A list of questions (feel free to use this article), so you don't forget anything.

Ideally schedule the viewing twice and at different times of day. Morning and evening will reveal different noise levels, and different weather will show you whether sunlight reaches the apartment or if water leaks in after rain.

Moisture and mold: the biggest hidden risks

Moisture is expensive to repair and bad for your 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 the corners around windows, corners, and areas behind furniture — that's where moisture collects and mold grows first.
• Watch the baseboards and lower edges of walls — peeling trim, bubbles under paint, or water stains indicate a problem.
• Basements, bathrooms, and kitchens are highest risk. In the bathroom, check the grout and caulk around the tub.
• If the apartment is freshly painted only in certain areas, ask why. It's not always a problem, but it's worth asking about.

Windows, utilities, and heating

These three things determine how much maintaining the property will cost you.

Windows and doors

• Open and close every window — does it move smoothly, does it seal, does it drag?
• Look for condensation between the panes (faulty double glazing) or cold drafts around the frame.
• For entrance and balcony doors, check the locks and seals.

Electrical installation

• Test the outlets (bring a charger) and turn on the lights.
• Look inside the circuit breaker panel — modern breakers and ground fault protection are a good sign; old aluminum wiring and porcelain fuses mean future rewiring.
• Ask when the last electrical inspection was done.

Heating and water

• Find out what type of heating is used (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.
• Turn on the water — check the pressure, color, and how quickly hot water arrives.

Noise, orientation, and light

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

• Open the window and just listen for a while. Traffic, bars, playgrounds, trams, train stations?
• Find out the orientation to the cardinal directions. A north-facing apartment will be darker and colder; south-facing may overheat in summer.
• Check if the view won't soon be blocked by new construction — ask about neighboring properties and developer plans.
• Test mobile signal right on the spot.

Common areas and surroundings (especially for apartments)

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

• Walk through the hallway, staircase, basement, storage, and elevator — well-maintained common areas mean a functioning owners' association and a healthy reserve fund.
• Pay attention to the facade and roof — insulation and a new roof are major expenses that can soon affect your fees.
• Ask about neighbors and whether the building has long-standing issues.
• Also explore the surroundings: parking, shops, public transit, access to daycare or schools.

Documents: what to request and verify

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

• Ownership certificate from the land registry — verify that the seller is actually the owner and that the property has no liens, judgments, or encumbrances. You can also obtain the current certificate yourself through the land registry.
• PENB (energy performance certificate) — shows energy efficiency roughly. When selling or renting, the law typically requires it (with exceptions) and it has a limited validity period. If it's missing, ask why.
• For apartments additionally: association bylaws, minutes from recent meetings, contribution amounts to the reserve fund and its balance, planned major repairs.
• For houses additionally: building documentation, completion certificate, inspections (chimney, gas, electrical), information about utilities and sewage (sewer vs. septic/treatment plant).

Tip: for a major investment, it's worth bringing a building inspector or property surveyor to the viewing. A few thousand for an inspection can prevent you from making a six-figure mistake.

Questions for the seller that reveal a lot

Don't be afraid to ask directly — you'll learn more from the reaction than from the answer itself.

• Why are you selling the property?
• How long has it been listed and how many interested buyers have there been?
• What does operating the property actually cost per year (utilities, reserve fund, property tax)?
• What has been repaired in recent years and what will need repair?
• Are all renovations permitted and completed?
• Is the price final, or is there room to negotiate?

Write down the answers right away. 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 parameters from viewings, they can be compared smartly. Assistants like ChatGPT, Claude, Perplexity, or Gemini can turn multiple listings into a clear table, flag risks, or build custom questions for a specific property.

For AI to see a listing at all, it must be on a platform that 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, the right listing can appear directly in the response. For sellers, it means one simple rule: post where AI can find you too. For buyers, it means you don't have to dig through dozens of portals.

Summary

A safe viewing rests on three things: prepare, check systematically, and ask questions. Go through moisture, windows, utilities, heating, noise, and common areas, request the ownership certificate and PENB, and bring in an inspector for larger investments. Only then sign. A few extra hours at the start will save you years of worry.

What should I bring to a property viewing?

Your phone for photos and notes, a charger to test the outlets, and a level (your phone has one). A list of questions is also helpful so you don't forget anything.

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

Pay attention to a musty or basement smell, peeling baseboards, bubbles under paint, and cold corners around windows or behind furniture. Fresh paint in winter can hide a problem — ask directly why the painting was done.

How many viewings should I do before deciding?

At least twice, and at different times of day — once in the morning and once in the evening for noise comparison. A second viewing will catch things you miss in the initial excitement.

Which documents should I request before buying?

Current ownership certificate from the land registry, energy performance certificate (PENB), and for apartments the association bylaws, meeting minutes, and reserve fund information. For houses, also get inspections and building documentation.

What is PENB and must the seller have it?

PENB is the energy performance certificate, which shows energy consumption roughly. The law typically requires it when selling or renting (with exceptions) and it's valid for a limited time — years typically. If the seller doesn't have it, ask why.

Can I record or photograph the viewing?

You should always ask the seller or agent, but usually there's no problem. 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 its response.
