What is the debt ratio?

The realization of a real estate project involves, for the applicant, to know his borrowing capacity, this in order to have a precise idea of ​​the amount he is able to borrow for good. To determine this capacity, banks use a tool based on the ratio between expenses and recurring revenues. This tool, called the debt ratio, makes it possible to estimate as much as possible the share of the budget dedicated to the repayment of monthly payments of the mortgage loan.
