FHA non-occupant co-borrower rules

What a non-occupying borrower is

The Handbook defines a non-occupying borrower transaction as one with two or more borrowers where one or more of them will not occupy the property as a principal residence. The classic case is a parent who co-signs for a child on the child's first home. The parent adds income or credit strength but does not move in. FHA allows this, and the rules below are the price of it.

The 75 percent limit, and its family exception

For non-occupying borrower transactions the maximum LTV is 75 percent. That is a big step down from the 96.5 percent available on an ordinary purchase, so with an unrelated co-borrower you would need at least 25 percent down. The limit can be raised to a maximum of 96.5 percent if the borrowers are Family Members, with two carve-outs: it does not apply where a Family Member is selling to a Family Member who will be a non-occupying co-borrower, and it does not apply to a transaction on a two- to four-unit property.

Example on a $280,000 purchase: with unrelated borrowers the maximum is 75 percent, or $210,000, requiring $70,000 down. With a parent and child, and a single-family home bought from a third party, the maximum is 96.5 percent, or $270,200, requiring $9,800 down. The calculator shows both tiers.

Title, note and security instrument

All occupying and non-occupying borrowers and co-borrowers must take title to the property in their own name or a living trust at settlement, be obligated on the note or credit instrument, and sign all security instruments. A non-occupant therefore cannot simply "vouch" for the loan. They are on the deed and on the debt. A co-signer is different: a co-signer is liable for the debt and signs the note, but holds no ownership interest and does not sign the security instrument. Do not mix the two terms when talking to a lender.

The U.S. connection

Non-occupying co-borrowers or co-signers must either be U.S. citizens or have a principal residence in the United States. A relative living abroad who is not a citizen does not satisfy this.

Whose income and credit count

The non-occupant's income can help you qualify, with one stated limit. For borrowers with no credit score, the qualifying ratios are computed using income only from borrowers who occupy the property and are obligated on the mortgage, and non-occupant co-borrower income may not be included. The credit side also bites: the MDCS is calculated for each borrower and the lowest is used, so a co-borrower with a 560 score drags the file to the 90 percent tier even if the occupant scores 720. See the credit score page for the arithmetic.

Existing FHA loans and the one-loan question

Having an FHA loan on your own home does not stop you from serving as a non-occupying co-borrower elsewhere. The Handbook's exceptions table says a borrower with an existing FHA mortgage on their own principal residence may qualify as a non-occupying co-borrower on other FHA-insured mortgages, and that a non-occupying co-borrower on an existing FHA mortgage may qualify for another FHA mortgage on a new property that will be their own principal residence.

Planning around it

Decide first whether the relationship qualifies as Family Member under the Handbook's own definition, because that unlocks the 96.5 percent tier. Then check the credit scores of both borrowers, and run the combined debts through the DTI calculator. Finally confirm with the lender, who can confirm how your relationship is treated and whether it sets stricter standards than the Handbook.
