Bank valuation estimator
What if the bank's valuation comes in below the agreed price?
Portuguese banks appraise independently of the agreed purchase price — and they often come in lower. RealOS estimates what the bank's valuation is likely to be before you apply, so there are no surprises after you've signed a deposit contract.

You sign a CPCV (Contrato de Promessa de Compra e Venda) and pay a deposit. The deposit is not returned if you withdraw without a valid reason. The bank appraises the property on its own. The loan is based on the lower of the agreed price and that appraisal. If the appraisal is lower, the mortgage is smaller and you need more of your own cash to complete.
Knowing the likely appraisal before you sign lets you negotiate the purchase price, confirm you have the cash buffer, or make the CPCV conditional on financing (condição suspensiva de financiamento).
How Portuguese banks appraise property
- Comparable method — The primary valuation method, using AT registered transactions for comparable properties in the same area over the past 24 months. Banks use a more conservative comparable set than RealOS's Fair Price Score — they exclude outlier transactions and apply a market adjustment factor.
- Income method — For investment properties, the bank may also apply an income capitalisation approach based on gross rental yield in the area.
- LTV limits — Banco de Portugal macroprudential rules cap LTV at 90% for primary residence (habitual residence) purchases and 80% for all other purchases. These are hard regulatory ceilings — Portuguese banks cannot lend above them.
- Floor: higher of appraisal or purchase price for LTV — LTV is calculated on the lower of the appraisal value and the purchase price. If the purchase price is lower than the appraisal, the LTV uses the purchase price. If the appraisal is lower — which is the risk scenario — LTV uses the appraisal.
