Adding a Non-Occupant Co-Borrower to an FHA Loan

Published by the Modern Lending Solutions editorial team. Last reviewed: October 30, 2026.

Short answer: on an FHA purchase loan, a person who will not live in the home can join you as a co-borrower. HUD’s Handbook caps the loan-to-value ratio (LTV) at 75 percent when a borrower will not occupy the home, and lets it rise to 96.5 percent when the borrowers are family members, with two exceptions. A non-occupant co-borrower takes title, signs the note and the mortgage, and is fully liable for the debt. A co-signer signs only the note and owns no share of the home. This page covers federal FHA rules only; for other loan types, ask the lender. It is general information, not legal or financial advice.

What HUD requires of every co-borrower

HUD Handbook 4000.1 says 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, and sign all security instruments; that a co-signer is liable for the debt and signs the note but holds no ownership interest and does not sign the security instrument; and that non-occupying co-borrowers and co-signers must be U.S. citizens or have a principal residence in the U.S. (II.A.1.b.ii(A)(4)-(6), HUD, Handbook update issued August 12, 2026, read October 30, 2026). The section heading in that file carries the date 11/10/2026, which is after our read date, so this part may change; ask the lender which version it follows.

The LTV limits

The Handbook calls a purchase with two or more borrowers, at least one of whom will not occupy the home as a principal residence, a Non-Occupying Borrower Transaction. Its maximum LTV is 75 percent. It can rise to 96.5 percent if the borrowers are family members, unless the transaction is (II.A.2.b.ii(B), section dated 02/16/2021):

• a family member selling to a family member who will be a non-occupying co-borrower; or
• a purchase of a two- to four-unit property.

HUD defines family member, regardless of sex or legal marital status, as a child, parent or grandparent (including step and foster relatives), a spouse or domestic partner, a legally adopted or foster child, a brother, sister, stepbrother or stepsister, an uncle or aunt, or an in-law of the borrower (II.A.1, sales contract requirements). A friend who will not live in the home is not on that list, so the 75 percent limit applies.

Credit scores matter too. Where a mortgage has several borrowers, the lender finds the Minimum Decision Credit Score for each one and uses the lowest; a score from 500 to 579 limits the LTV to 90 percent, 580 or above allows maximum financing, and below 500 is not eligible (II.A.1.b.ii(A)(3) and II.A.2.b.i). A co-borrower with a lower score than yours can therefore cut the loan amount. The loan amount is also capped by the FHA limit for the area; see FHA loan limits.

Example: three cases

This example is only for the math, with an example value, not terms from any lender. It assumes an Adjusted Value of $300,000, a one-unit home and a loan amount within the area limit, and leaves out the upfront mortgage insurance premium and closing costs.

In this example, the 75 percent case needs $64,500 more down than the 96.5 percent case. A family member may also give part of the down payment as a gift; see mortgage gift funds rules and FHA mortgage insurance premiums.

Income and later loans

The Handbook adds limits on using a non-occupant co-borrower’s income: it may not be used in the qualifying ratios when the borrowers have no credit score and are manually underwritten (II.A.5), and it may not be used to qualify for a cash-out refinance (II.A.8, cash-out refinances; that section also carries the date 11/10/2026). It also says a non-occupying co-borrower on an existing FHA loan may qualify for another FHA loan on a new home to be their own principal residence, and that a borrower with an FHA loan on their own principal residence may be a non-occupying co-borrower on other FHA loans (II.A.1.b.iii, exceptions to the policy limiting the number of FHA mortgages per borrower).

Co-borrower or co-signer

Either way, the debt can follow them. When the co-signer or co-borrower later applies for an FHA loan of their own, the Handbook treats a co-signed debt as a contingent liability whose payment counts in their monthly obligations, unless the lender documents that the creditor will not pursue them or that the other party has made 12 months of timely payments (II.A.4, contingent liabilities). See the risks of cosigning a loan and joint loans vs cosigners.

The FTC Notice to Cosigner

The FTC Credit Practices Rule says a lender or retail installment seller within the FTC’s jurisdiction may not obligate a cosigner unless the cosigner is first told the nature of their liability, and it may not misrepresent that liability; giving the cosigner a separate Notice to Cosigner before they become obligated meets the rule (16 CFR 444.3(a)-(c), eCFR, text up to date as of October 28, 2026). The notice says, among other things, that the cosigner may have to pay up to the full amount of the debt plus late fees or collection costs, that the creditor can collect from the cosigner without first trying to collect from the borrower, and that a default may become part of the cosigner’s credit record. The rule defines a cosigner as a person who becomes liable for another’s obligation without compensation, and says a person who does not receive goods, services or money in return does not receive compensation (16 CFR 444.1(a) and (k), eCFR). A non-occupant co-borrower takes title to the home, so ask the lender whether it treats them as a cosigner and gives the notice; for a legal answer, talk to a lawyer.

A note on 24 CFR 203.18

HUD’s regulation on maximum mortgage amounts lets an eligible non-occupant mortgagor borrow up to the amount for the loan type (eCFR 203.18(c), text up to date as of October 28, 2026), but it defines that term narrowly: a public entity or governmental unit, certain nonprofit organizations, an Indian tribe, a service member kept away by a duty assignment, a borrower under Section 203(k), or a borrower on certain FHA-to-FHA refinances that lower the payment (203.18(f)(3)). It does not cover a relative who joins a homebuyer. The family member rules above come from the Handbook.

Questions to ask the lender

• Does my co-borrower count as a family member under HUD’s definition, and what is our maximum LTV?
• Whose credit score sets the limit, and what happens if my co-borrower’s score is lower than mine?
• Can my co-borrower’s income be used on this loan?
• How will my co-borrower be listed on the title, the note and the mortgage?
• Will you give my co-borrower or co-signer a Notice to Cosigner?
• If my co-borrower later wants off the loan, what are the options?

Checklist for the co-borrower

• Read the note and mortgage before signing: you owe the full debt if the payments stop.
• Expect the loan to show on your credit reports and to count against your own borrowing.
• Agree in writing with the occupant who pays the mortgage, taxes, insurance and repairs.
• Ask a lawyer how shared title affects a later sale, a divorce or an estate.
