Illustrative example. Your own numbers will differ.

What you get

The real acquisition stack

IMT on the 2026 mainland brackets with their deductible portions, Imposto do Selo on both the purchase and the loan, and notary and registry costs — including the flat 7.5% rate that now applies to non-resident buyers.

Financing and cash flow

Monthly payment, total cash you actually need at the table, and what the property leaves you each month — before and after tax.

Compared to official data

Your price per m² set against the INE median for the area, so you can see whether the asking price is defensible.

A transparent Deal Score

One number out of 100, with every component shown and its points broken out. Nothing hidden in a black box.

What this is, and isn't

Imofonte gives you estimates for mainland Portugal, built from published rates and official benchmark data. Figures marked as estimates are exactly that — an IMI estimate is not a VPT valuation, and default operating costs are placeholders, not quotes. This is a tool for sizing up a deal quickly. It is not tax advice, and it does not replace a solicitor or an accountant.
