Boarder income is considered a form of "accessory unit rental income" by Fannie Mae, allowing homeowners to include it as part of their qualifying income for a mortgage.

Lenders may allow up to 30% of the total qualifying income to come from boarder payments, provided the income is properly documented.

For a boarder's income to be counted, they must be renting a room within the homeowner's primary residence, not a separate living unit with its own kitchen and bath.

Boarder income is treated differently for VA loans compared to conventional or FHA loans - as of 2018, VA loans do not allow boarder income to be counted towards the debt-to-income ratio.

The lender will calculate the average monthly boarder income based on the most recent 12 months of payments, even if the boarder hasn't been there the full year.

Proper documentation of boarder income includes a current lease agreement and evidence of payment, such as bank statements or canceled checks.

Boarder income is considered "stable and reliable" by lenders, provided the homeowner can demonstrate a history of receiving the payments.

The boarder must have unrestricted access to the home and be able to come and go freely, rather than being a tenant in a separate living space.

Boarder income is treated differently from rental income from an investment property, which undergoes a more rigorous underwriting process.

Homeowners can use boarder income to qualify for a larger mortgage loan amount than they would be able to without the additional revenue stream.

The tax implications of boarder income vary - in some cases it must be claimed as taxable income, while in others it may be exempt up to a certain threshold.

Boarder income can help make homeownership more accessible for individuals who may not otherwise qualify for a mortgage on their primary income alone.
