B3-4.3-13, Sweat Equity (04/15/2014)

Generally, sweat equity is not an acceptable source of funds for the down payment, closing costs, and reserves, since it is difficult to accurately assess the contributory value of sweat equity work. Only for specific transactions and if all eligibility requirements are met does Fannie Mae consider sweat equity to be an acceptable source of funds.

For further detail on the specific transactions and the eligibility requirements to be met, see Chapter B5–6, HomeReady Mortgage.
