Automated property valuation you can verify.
Aurentis values Tallinn apartments with a machine-learning model trained on 39,158 Land Board transactions. Unlike free calculators, we publish our model's error. Unlike a certified appraisal, you get the result in 30 seconds.
Comparable sales, explanations and a PDF — every line verifiable. Regular price €19.

For agents and banksWe have no price to defend.
Aurentis is an independent analytics firm. We are not owned by any real estate agency, we do not broker transactions and we earn no commission. Our only product is the valuation itself — which is why we can afford to keep it honest.
We do not pass your details to agents or sell leads. A valuation here is not a lead trap — you get the result without anyone calling you.
We earn from reports, not transactions. We have no reason to flatter the price up or down — we receive no commission either way.
Buyer, seller, agent and bank see the same methodology, the same range and the same published error. Independence you can verify, not a promise.

Our approach
Validated model
Estimates are compared against historical transactions. The report shows the model version, data period and confidence score.
Verifiable assumptions
Every estimate shows which inputs, registry data and market signals influenced the result.
Not a single number
Aurentis shows a value range, because property value depends on the market, liquidity and the property's characteristics.
Audit trail
Every estimate is logged: timestamp, inputs, model version. Suitable for institutional documentation.
