Support Counts Both Ways, and the Conditions Are Stricter Than People Expect
Program and regulatory figures verified October 10, 2026. Details change; confirm your scenario with us.
The section is titled "Alimony, Child Support, Equalization Payments, or Separate Maintenance". Fannie Mae has written a rule with the word equalization in it, and it is not the rule people hope for.
★★ First: it only counts if you ask
Selling Guide B3-3.4-02, dated 7 October 2026, opens:
"The lender may include alimony, child support, equalization payments, or separate maintenance as income only if the borrower discloses it on the Uniform Residential Loan Application and requests that it be considered in qualifying for the loan."
★★ Support is not swept in automatically. If it is not disclosed and requested, it is not income. ★ That is the easiest thing on this page to get wrong and the easiest to fix, tell us about it.
★★★ The condition that disqualifies the most people
"Income Continuance. The lender must document that the income is expected to continue for at least three years from the application date. Note: Check for limitations such as the age of the children for whom the support is being paid, or the duration over which alimony is required to be paid."
★★★ Three years, from application. So child support for a sixteen-year-old is a problem, because the obligation will not run three more years. Alimony with a defined end date inside three years is the same problem.
★★ This catches people badly, because the support is real, it is arriving, and it still cannot be used. The practical response is to find out early how long the order actually runs, before a purchase or buyout is priced on income that will not qualify.
★★★ And the sentence aimed straight at divorce buyouts
"Note: Lump sum equalization payments are not considered a steady source of income."
★★★ A one-off equalisation payment, the very thing a buyout often produces for the spouse being bought out, is not qualifying income. It is a sum of money, and it may well help as assets or as a down payment on a next home, but it does not help the income side of a debt-to-income calculation.
★★ If you are the spouse receiving the buyout and planning to purchase, that distinction shapes what you can buy. Plan on the assets, not on the income.
★ What has to be documented
Evidence of the amount and terms, by one of: a divorce decree or separation agreement (if the divorce is not final); any other written legal agreement or court decree describing the payment terms; or documentation verifying an applicable state law mandating the payments.
★ Plus receipt of the income for the most recent six months: bank statements, cancelled cheques, or evidence of other electronic receipt. And a minimum six-month history demonstrating "full, regular, and timely payments."
★★★ With a pointed note for anyone separated but not divorced:
"If a borrower who is separated does not have a separation agreement that specifies alimony or child support payments, the lender should not consider any proposed or voluntary payments as income."
★★ Informal generosity during a separation does not qualify, however reliable it has been. If support is meant to be counted, it has to be written down.
★ One point in your favour
The guide notes that "the full amount of documented qualifying child support income is nontaxable and may be grossed up." ★ That can meaningfully improve a qualifying picture. Ask about it rather than assuming it has been applied.
★★ The other direction: support you pay
Selling Guide B3-6-05, Monthly Debt Obligations (dated 5 August 2026), covers "Alimony, Child Support, Equalization Payments, and Separate Maintenance Payments" on the obligation side, what happens when the borrower is required to pay.
★★ The symmetry matters in a divorce. The same order can reduce one spouse's qualifying capacity and increase the other's, and the amount and duration agreed in a settlement therefore shapes what each of you can borrow afterwards. ★★★ That is a reason to have the financing conversation while terms are being negotiated, not after. What qualifying on one income looks like.

Frequently asked questions
Can I use alimony or child support as income for a mortgage?
Yes, subject to conditions. Fannie Mae B3-3.4-02 requires that you disclose it on the loan application and request it be considered, that the amount and terms be documented by a decree, separation agreement or other written legal agreement, that receipt be shown for the most recent six months, and that the income be documented to continue at least three years from the application date.Does a lump-sum divorce equalization payment count as income?
No. Fannie Mae B3-3.4-02 states that lump sum equalization payments are not considered a steady source of income. Such a payment may still help as assets or toward a down payment, but it does not support the income side of a debt-to-income calculation.What if support will end within three years?
It generally cannot be used. The guide requires the income to be expected to continue for at least three years from the application date and specifically directs lenders to check limitations such as the age of the children receiving support or the duration over which alimony is required to be paid.Do voluntary payments during a separation count as income?
No. Fannie Mae B3-3.4-02 states that if a borrower who is separated does not have a separation agreement specifying alimony or child support, the lender should not consider any proposed or voluntary payments as income.Can child support income be grossed up?
Fannie Mae notes that the full amount of documented qualifying child support income is nontaxable and may be grossed up. Ask your lender whether that treatment has been applied to your file rather than assuming it.Mike Certo · NMLS #260555 · Cornerstone First Mortgage NMLS #173855 · Equal Housing Lender.
