How do mortgages work in Guinea-Bissau?
Like most countries, mortgages in Guinea-Bissau use the French amortisation system: constant monthly payments throughout the life of the loan. The formula is C = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r the monthly interest rate and n the total number of instalments. The local currency is the XOF (CFA).
Reference interest rate in Guinea-Bissau
The standard reference index for variable-rate mortgages in Guinea-Bissau is the central bank reference rate. For variable mortgages, the applied rate = reference index + spread agreed with the lender. Reviews are typically annual or semi-annual.
