What you pay each month and what you need to earn
Monthly payment, the minimum income under the 45 % debt-service limit, the deposit and every tax at the deed — under the Banco de Portugal rules in force since August 2026 and the dated average market rate.

What this sum leaves out
Life and home insurance, the bank's fees (valuation, file, processing) and each bank's spread are not here: they differ from bank to bank. LTV counts the price as the property's value; if the bank's valuation comes in below the price, the bank lends on the valuation and the deposit goes up. Stamp duty on interest is paid with every instalment; we show the first month's.
