The National Housing Trust (NHT) will now allow up to three contributors to apply for a two-bedroom or larger housing unit.
At present, only two contributors can join their contributions to make home purchases.
Prime Minister Andrew Holness says the new policy will ensure that more persons can access housing.
However, only family members can join their benefits.
Effective July 1, 2022, the Trust will also revise its policy on subsidies to make income the sole determinant of whether a subsidy is applied to a loan.
That means some mortgagors could see their interest rate going up if their circumstances improve.
