Article Summary

Boarder income is a homeowner's earnings from people who rent and live in spare rooms or sections of a home.

Boarder Income: Explained in Plain English

In real estate, boarder income is the revenue a homeowner earns for housing tenants, known as boarders, within their residential property. Boarder income is common in single-family homes where extra rooms or separate living areas are rented.

Unlike traditional rental income, which is earned when an entire property is leased to a renter, boarder income refers to rent payments received when the renter cohabitates with the owner.

The most common boarder income scenario is when a homeowner rents out one or more spare bedrooms to students, professionals, or short-term lodgers, and shares common areas like the kitchen and living room with the boarders.

Other boarder income scenarios include:

  • Renting a self-contained basement unit or accessory dwelling unit to a renter
  • Renting a room to a family member through an informal rental agreement

Boarder income is a common way for homeowners to supplement household income, offset mortgage payments, or cover home maintenance costs. Boarder income can also help in qualifying for a mortgage.

Homeowners who receive boarder income are expected to declare it for tax purposes and ensure their home meets local housing laws and standards.


Boarder Income: A Real World Example

Consider a first-time home buyer in a college town with an extra bedroom over the garage, equipped with its own bathroom and living space. The room presents an opportunity to house a student needing affordable housing, generating income to help offset the mortgage.

The homeowner sets up the room and offers it for rent.

The arrangement benefits both parties: the student gets affordable accommodations near campus, and the homeowner receives income to cover part or all of the mortgage, reducing financial burdens.
