> When boarder income for a mortgage counts, the shared-residence history lenders need, and how rent payments from a roommate show in bank statements.
Boarder income for a mortgage counts only in narrow cases: on a HomeReady loan, or for a borrower with disabilities who rents to a live-in assistant. The boarder must have shared the borrower's home for 12 months and paid rent regularly, shown on bank statements or canceled checks. Fannie Mae caps it at 30 percent of qualifying income.

## When does boarder income count for a mortgage?

Rent from a boarder, meaning a person who rents a room in the borrower's own home, is usually not stable income for a mortgage. Fannie Mae's section on [boarder income](https://selling-guide.fanniemae.com/sel/b3-3.4-04/boarder-income) makes two exceptions: a borrower with disabilities receiving rent from a live-in personal assistant, and loans under the HomeReady program.

### Why the default answer is no

A boarder can leave with a month's notice. Unlike a tenant in a separate unit with a lease, a roommate is often a friend, a sibling or a coworker, and the arrangement can end when either side's life changes. Lenders treat that income as too fragile to carry a thirty-year payment on its own.

### The personal assistant exception

When a borrower with disabilities pays a live-in personal assistant partly by providing a room, the assistant's rent payments can count. Fannie Mae allows this whether or not the assistant is a relative, up to 30 percent of the total gross income used to qualify.

### The HomeReady exception

HomeReady is Fannie Mae's program for low to moderate income buyers. Its [underwriting methods and requirements](https://selling-guide.fanniemae.com/sel/b5-6-02/homeready-mortgage-underwriting-methods-and-requirements) let a borrower count rent from a boarder on a one-unit property, up to 30 percent of total gross qualifying income. The boarder may be related or unrelated, but cannot be on the mortgage or hold any ownership interest in the home.

### Other lenders and programs

Programs outside Fannie Mae set their own rules. Many do not count boarder income at all. Ask before you build a file around it, since the answer changes which documents you need.

## The shared-residence history a boarder must show

The boarder must have lived with the borrower for the past 12 months, and the lender needs papers that prove it. Fannie Mae lists examples: the boarder's driver's license, bills, bank statements or W-2 forms showing the borrower's address as the boarder's own. One or two documents dated across the year usually tell the story.

### Documents that work well

- A driver's license or state ID issued to the boarder at the borrower's address.
- Utility or phone bills in the boarder's name at the address.
- The boarder's bank statements or pay stubs mailed to the address.
- The boarder's W-2 listing the address.

### When the history is short

A boarder who moved in seven months ago has not yet met the 12-month history. The borrower can still apply, but without the boarder's rent in the qualifying income. If the borrower is close to qualifying, waiting until the history is complete may be the better plan.

### A relative as the boarder

HomeReady allows a related boarder, so an adult child or a parent paying rent can count. Relatives are where documentation slips most often. Family members tend to pay irregularly, in cash or by covering groceries instead of rent. Agree on a fixed monthly amount, paid by transfer, and keep that up for the full year before applying.

### When the boarder moves with the borrower

HomeReady often finances a purchase, so the borrower may be buying a new home and bringing the boarder along. The history is about the two people living together, not about the new property. Rent paid at the old home shows the arrangement has held.

## Boarder rent payments in bank statements

Rent from a boarder shows on the borrower's statements as a regular deposit, usually monthly, from the boarder's name or from a payment app. The lender wants 12 months of these receipts. Under HomeReady, payments for at least 9 of the last 12 months are acceptable, averaged over the full year.

### What a clean pattern looks like

The best evidence is boring: the same amount, from the same person, on about the same date each month. A boarder who pays by bank transfer with their name in the description is the easiest to document. Payment apps are also fine, as long as the description or the app's history shows who sent the money.

### Worked example: twelve months with one missed payment

The figures are an example for illustration. A boarder rents a room for 750 a month on a HomeReady purchase.

| Month (example) | Rent received |
| --- | --- |
| January to April | 750 each month |
| May | 0, boarder away for a family emergency |
| June to December | 750 each month |
| Total, 12 months | 8,250 |

The boarder paid in 11 of 12 months, which meets the 9-of-12 rule. HomeReady averages the receipts over 12 months: 8,250 divided by 12 is 687.50 a month. That figure, not the 750 the borrower quotes, goes into the qualifying income.

### Finding the payments among other deposits

A borrower with a roommate often also receives payroll, refunds and transfers from family. [TrueBankFlow](/) groups deposits from the same source on a regular schedule, with their cadence and average amount, so the boarder's rent stands out as its own line. For the method of turning a year of deposits into a yearly figure, see [how to calculate annual income from bank statements](/blog/how-to-calculate-annual-income-from-bank-statements).

## How much boarder income can a borrower use?

A borrower can use the documented monthly boarder income up to 30 percent of the total gross income used to qualify. The cap includes the boarder income itself, so the boarder's rent can be at most about 43 percent of the borrower's other income. Above that, the extra does not count.

### The cap test in the example

Continuing the example, suppose the borrower earns 4,200 a month in wages. Total qualifying income is 4,200 plus 687.50, or 4,887.50. Thirty percent of that is 1,466.25. The boarder income of 687.50 is well under it, so it counts in full.

### When the cap binds

Now suppose the borrower earns 3,000 a month and the boarder pays 2,000. The boarder income can be no more than 30 percent of the total that includes it. Solving for that, the boarder income is capped at about 1,286 a month. The lender would use 1,286, not 2,000, giving qualifying income of about 4,286.

### Other household income

Boarder rent often sits next to other kinds of help in a household. A borrower who also receives payments for children in their care has a separate income type with its own rules, covered in [foster care income for a mortgage](/blog/foster-care-income-for-mortgage).

## Boarder income paid in cash or to a third party

Rent paid in cash, or paid by the boarder straight to the borrower's landlord or utility company, is the most common reason boarder income fails. HomeReady does not accept rent the boarder pays directly to a third party. Cash handed over in person leaves no record unless the borrower deposits it in a way that ties it to the boarder.

### Cash rent

If the boarder pays in cash and the borrower deposits it, the statement shows an anonymous cash deposit. The lender cannot tell it from any other cash. A receipt book with the boarder's signature may help, but the safer path is to ask the boarder to start paying by check or transfer, and to apply once 12 months of traceable payments exist.

### Rent paid on the borrower's behalf

Some roommates pay a share of the electric bill or the landlord directly. That is real help, but it is not boarder income under HomeReady. Restructure the arrangement so the boarder pays the borrower, and the borrower pays the bills.

### A boarder who travels for work

A boarder who travels for long stretches, such as a nurse on rotating contracts, may still live at the borrower's address and pay rent between assignments. Document the address on their tax forms and licenses. [Travel nurse income for a mortgage](/blog/travel-nurse-income-for-mortgage) explains why a traveling worker's tax home matters, which can help show where the boarder lives.

## Roommate rent versus rental income from a unit

Room rent from a boarder and rent from a separate unit are different income types. A boarder shares the borrower's living space. A tenant in a basement apartment, a duplex unit or a separate dwelling has a home of their own. Rent from a unit follows rental income rules, which usually rely on a lease and tax returns.

### Why the distinction matters

A borrower who calls a tenant a boarder may meet the wrong documentation rules. A borrower who calls a boarder a tenant may expect a lease to carry income that the program will not count. Describe the arrangement accurately and choose the rule that fits it. [How rental income shows up on bank statements](/blog/rental-income-on-bank-statements) covers the unit side of the line.

### When the property changes the answer

HomeReady's boarder rule applies to a one-unit property. A borrower buying a two-unit home and renting the second unit has rental income, not boarder income, even if the tenant is a friend.
