The quickest way a lender sizes up a mortgage application is the debt service ratio: total monthly debt payments divided by gross monthly income, expressed as a percentage. If you earn J$400,000 a month and your proposed mortgage payment plus car loan and card payments come to J$140,000, your ratio is 35 per cent.
Jamaican lenders each set their own ceilings, and many apply two tests: one for the housing payment alone, including property tax and insurance where these are collected with the mortgage, and one for all debts combined. The National Housing Trust applies its own affordability rules when deciding how much it will lend. A ratio above the lender’s limit usually means a smaller loan, a longer term, a co-applicant or a larger deposit.
Some practical points: lenders look at income they can verify, so cash earnings without records count for little. Clearing or reducing a car loan before applying can lift the amount you qualify for. Overseas income may be accepted, but lenders may discount it for currency risk. Bear in mind that a ratio a lender will accept is not necessarily one your household budget can comfortably bear. In Canada the same idea is split into gross and total debt service ratios with official stress tests; Jamaica has no single regulatory cap for all lenders.
