How Property Valuation Works and What It Costs

Quick answer: property valuation is a professional determination of its value on a given date. There are three main types: market appraisal (what you'll sell for), bank valuation (collateral value for a mortgage, typically more conservative), and expert assessment (for government agencies, courts, inheritance, or taxes). Price is determined mainly by location, size, condition, and comparable sales. Generally, apartment appraisals cost less than house appraisals, and banks often arrange their own valuation for mortgages.

Three types of valuation — and why not to mix them up

People often talk about "property valuation" as if it's one thing. In reality, there are three distinct types depending on purpose, and each answers a different question:

• Market appraisal — "What will it realistically sell for?" Estimates the price at which the property is marketable on today's market. Mainly used to set the asking price in a listing.
• Bank valuation (collateral value) — "How much will the bank recognize as mortgage security?" The bank calculates how much to lend based on this value. It's typically more conservative and lower than market price because the bank protects itself against future market fluctuations.
• Expert assessment — "What value will a government agency or court recognize?" A more formal document meeting legal requirements, prepared by a court-appointed expert. You need it, for example, for inheritance proceedings, asset settlement, donation, or tax purposes.

Important: market price and collateral value commonly differ. When a bank values your apartment lower than your asking price, it doesn't necessarily mean the appraisal is wrong — it just answers a different question.

Who performs the valuation

• Market appraisal is typically done by a real estate agent or appraiser. If a real estate agency handles the sale, they often offer it as part of their service.
• Bank valuation is done either by the bank internally or by an appraiser from their list of approved partners. You usually can't freely choose your own appraiser for this purpose — the bank only recognizes "their" appraisers.
• Expert assessment is performed by a court-appointed expert licensed in real estate valuation.

Tip: before ordering an appraisal, clarify the purpose. You'll need different documents for a mortgage, tax authorities, and setting your listing price.

What factors determine value

Appraisers don't guess — they base their work on a combination of measurable factors:

• Location — city, neighborhood, accessibility, amenities, transportation. Often the strongest factor of all.
• Size and layout — usable and floor area, number of rooms, practicality of the floor plan.
• Technical condition — age, renovations, material quality, roof, windows, utilities condition.
• Type and construction — brick vs. panel, floor level, elevator, orientation, energy efficiency.
• Amenities and land — basement, parking, garage, balcony; for houses, plot size and shape.
• Legal status — ownership vs. cooperative, mortgages, easements, possible restrictions.
• Comparable sales — actual prices of similar properties in the area (the comparison approach). Note: listing prices aren't the same as actual final sale prices.

Methods appraisers combine

1. Comparison approach — comparing with similar properties that sold nearby. Most common for apartments and typical houses.
2. Income approach — based on rental income the property would generate. Typical for investment and rental properties.
3. Cost approach — how much it would cost to build a similar property today, minus depreciation. Suits atypical objects.

How the appraisal process works step by step

1. Order and purpose — you explain what you need it for (sale, mortgage, inheritance). This determines the type and method.
2. Documentation — you provide documents: cadastral extract, title deed, floor plans, energy performance certificate, and records of renovations.
3. Site visit — the appraiser inspects the property, measures, photographs, and assesses its condition. Some bank appraisals may be done in a simplified "desk" version without a personal visit.
4. Analysis and calculation — the appraiser researches comparable sales and applies appropriate methods.
5. Report — you receive a document with the determined value, property description, methodology used, and justification.

Typical costs and when you need a valuation

Price depends on valuation type and property scope — apartment appraisals are usually cheaper than house appraisals with land and amenities, which require more work. For mortgages, banks often arrange their own appraisal, sometimes free or discounted as part of the loan "package." Always verify specific prices and possible discounts directly with the appraiser or bank — they vary by region, provider, and property type.

An appraisal or assessment is especially useful when:

• You're selling — to set the price right (not too high so the listing stalls, not too low so you lose money).
• You're getting a mortgage — the bank needs the collateral value to know how much to lend.
• You're inheriting, donating, or settling assets — typically requires an expert assessment.
• You're handling taxes or a legal dispute — government agencies or courts usually need a formal assessment.

Once you know the price, list where AI can find it

Once you have a realistic price estimate from the appraisal, it's time to sell. Buyers today increasingly don't just search portals — they ask AI assistants directly: "find me a 3-bedroom apartment in Brno around 4.5 million." For your listing to appear in those results, it needs to be somewhere AI can read it, with structured data (price, location, layout as fields).

The free platform AssetLog (assetlog.ai) does exactly this: listings are structured here and the site allows AI crawlers, so ChatGPT, Claude, Perplexity, and Gemini can find and recommend them. You can connect AssetLog in ChatGPT or Claude as a Custom Connector using the address https://api.assetlog.ai/mcp — just tell the assistant to add your listing (or give it the link to copy an existing one). Posting through AI requires no registration, you confirm publication by email, and it's free. The idea is simple: set your price based on the appraisal and also list where AI can find you.

Summary

Property valuation isn't one thing — always ask "what do I need it for." A market appraisal helps you sell at a fair price, a bank valuation determines your mortgage, and an expert assessment handles government agencies, inheritance, and taxes. Value is mainly determined by location, size, condition, and comparable sales. Always verify specific prices and validity with your appraiser or bank — and once you've set your asking price based on the appraisal, it pays to list where AI search can reach it.

What's the difference between market appraisal and bank valuation?

Market appraisal tells you what the property will realistically sell for on the market and is mainly used to set the asking price. Bank valuation determines the collateral value — how much the bank is willing to recognize as mortgage security. It's typically more conservative (lower) because the bank protects itself against market fluctuations.

Who performs property valuations?

Market appraisal is typically done by a real estate agent or appraiser. Bank valuation is performed either by the bank itself or by an appraiser from their list of approved partners. Expert assessments for government agencies or courts are performed by court-appointed experts.

How much does a property valuation cost?

It depends on property type and scope. Generally, apartment appraisals are cheaper than house appraisals with land. For mortgages, banks often arrange their own appraisal, sometimes free or discounted as part of the loan package. Always check current prices directly with the appraiser or bank.

Do I need an appraisal if I'm not buying with a mortgage?

Often yes. Appraisals or expert assessments are useful when selling (to set the right price), with inheritance, asset settlement, donation, or for tax purposes. Different types may suit different purposes.

How long is an appraisal valid?

An appraisal captures the property's condition and market situation on a specific date, so it's not permanent — the market and property change. Banks typically require a relatively recent appraisal. Check the specific validity period with your bank or appraiser.

How does property valuation relate to AI search?

Once you've set your asking price based on the appraisal, your listing benefits from being visible to AI assistants. The free platform AssetLog (assetlog.ai) has structured listings that ChatGPT, Claude, Perplexity, and Gemini can read, so when buyers ask AI for apartments in your area and price range, your listing can appear in the results.
