First, choose who will be on the loan
People searching for a “Family Opportunity Mortgage” often have one of two arrangements in mind. Knowing which one you need changes whose income and credit the lender reviews.
From an actual closed loan
Parents with savings, fixed income, and a son who helped
In a conventional purchase handled by Shahram Sondi, the parents had fixed income and substantial money in a regular savings account. The savings balance did not provide the additional qualifying income they needed for that loan.
Their son already had a mortgage on his own home. He joined their loan as a non-occupying co-borrower, helped them qualify, and the purchase closed.
- Reported purchase price
- About $350,000
- Down payment in this case
- 5% about $17,500
- Base loan from those figures
- About $332,500
Anonymous completed case, described by Shahram. Dollar figures are calculated from the approximate purchase price and reported down payment. Down payment is not total cash needed at closing. This historical example is not a current offer, a promised down payment, or an approval for another family.
The lesson: ask what the assets can actually do
A savings balance and qualifying monthly income serve different purposes. In this case, the money was in ordinary savings, not an IRA from which qualifying retirement distributions were being received. Adding the son addressed the income problem.
Fannie Mae generally excludes ordinary checking and savings from its employment-related asset-income calculation, unless the money came from an eligible employment-related source. Separate rules may apply to qualifying interest, dividends, or retirement income. Account type, source, and documentation matter.

This closing used the joint-borrower arrangement. The child-only option below is a separate guideline-based explanation.
Checklist: when the child can be the only borrower
- The parent meets the exception. The parent is unable to work or has insufficient income to qualify independently. The rule does not impose a parent savings cap. Poor credit by itself is not the stated test.
- The home will house the parent. Describe the actual living arrangement. The child can live elsewhere and must answer the occupancy question truthfully.
- The child qualifies. The lender verifies the child’s income, credit, debts, and eligible funds. Existing housing obligations still need to be evaluated.
- The child owns the home and owes the debt. The child takes title and signs the loan documents. Parents do not have to be on the deed or loan.
- The property and purchase meet the loan rules. Down payment, closing funds, reserves if required, property eligibility, insurance, and any condo-project review still apply.
- The lender confirms the exception. Primary-residence treatment does not automatically produce an underwriting approval.

Hypothetical example: parents with no qualifying income
A daughter wants to buy a home for parents who have no qualifying income. She plans to remain in her own home. If she qualifies for the new loan and the lender verifies the parent-housing exception, she may be the sole borrower and owner while her parents live in the purchased home.
If the parents are not borrowers, their credit is not used to qualify her loan. This is an illustration of the rules, not another closed case or an approval.
What the lender checks: income, credit, and cash
Can your income support the obligations?
The debt-to-income ratio compares qualifying monthly debt payments with qualifying gross monthly income. The review includes the new housing payment, existing housing obligations, and other debts, subject to any properly documented exclusions.
Fannie Mae’s Desktop Underwriter, or DU, allows a maximum total ratio of 50%. Manual underwriting generally starts at a 36% limit and can reach 45% with the required qualifications. Those are ceilings, not promises of approval or a recommendation for your household budget.

What credit score is needed?
Current Fannie Mae DU rules do not impose a universal minimum credit score. DU evaluates the full credit risk. Manual underwriting generally has minimums of 620 for fixed-rate loans and 640 for adjustable-rate loans, with potentially higher requirements. The lender and mortgage insurer may have additional standards.

How much do you need to put down?
The parent-housing exception does not set a separate down-payment minimum. The selected mortgage product and full application control. Do not assume a program allowing 3% down automatically works: Fannie Mae’s loans above 95% financing carry additional occupancy and eligibility conditions that must be resolved for the specific file.
Fannie Mae B2-1.3-01: Purchase Transactions
For the separate non-occupying co-borrower arrangement, Fannie Mae generally caps financing at 95% of the property value under DU and 90% under manual underwriting. Manual files also have occupying-borrower income and contribution conditions. These co-borrower rules should not be automatically applied to a child who qualifies as an owner-occupant under the parent-housing exception.

How much money must remain after closing?
There is no blanket reserve minimum for a one-unit primary-residence purchase under DU, but the risk assessment can require reserves. Reserves are eligible funds left after closing. They are separate from the money used for the down payment and closing costs. A lender may have stricter requirements.

Use the closing-cost guide to plan the other upfront expenses, then ask for a review of the complete family arrangement.
What to prepare before you make an offer
Start with these items. This is a practical preparation list; Fannie’s occupancy exception does not prescribe one universal parent-document package.
- Your income and employment information: pay records and other documents appropriate to the income you use.
- Your existing housing and debts: mortgage statements, rent, and other obligations the lender needs to evaluate.
- Funds for the purchase: statements for the eligible funds you plan to use, plus documentation for any permitted gift.
- The parents’ housing situation: who will live there and why the parent cannot qualify independently. Benefit or income statements may help establish the situation; the lender decides what evidence is needed.
- The property and ownership plan: intended purchase price, property type, and who you want on the deed and loan.
Ask the lender to review the occupancy exception before relying on a generic online prequalification. Confirm the required down payment, how existing housing costs are counted, and what documents remain outstanding.

When this approach may not fit
The child-only route can fail when the parent does not meet the exception, the child cannot qualify for the obligations, or the property does not meet the loan requirements. A lender may also have restrictions beyond Fannie Mae’s baseline.
Joining as a co-borrower deserves a separate review when the parents remain on the loan. Adding a child does not remove the parents’ credit from that application. It also makes the child responsible for repayment and can affect the child’s ability to borrow later.
Start with the actual family situation, then choose the loan structure. A search term or program nickname cannot decide that for you.
Questions about buying a house for your parents
Can I buy a home for my parents if I already have a mortgage?
Yes, an existing mortgage does not automatically prevent it. The lender must evaluate the new payment, your existing housing obligations, and your other debts against your qualifying income. A specific exclusion needs to meet the applicable loan rules.
Can my parents live in the home without being on the loan?
Yes, if the parent-housing exception applies and you qualify as the borrower. Fannie Mae's submission instructions specifically allow a primary-residence transaction in which no borrower will occupy the home, provided the lender verifies the exception.
Fannie Mae Selling FAQs: Eligibility and Insurance Assessment, question 5
Do my parents have to be on the deed?
No. The child can be the borrower and owner. If parents are added as owners without becoming borrowers, they must sign the security document that places the mortgage lien on the property, but do not necessarily sign the note promising repayment. Have the lender and title company confirm the ownership arrangement before closing.
Can I use this option just because my parents have bad credit?
Poor credit alone is not the stated test for Fannie Mae's parent-housing exception. The rule calls for a parent who is unable to work or does not have sufficient income to qualify independently. If the parents are also borrowers, their credit remains part of the loan review.
Do my parents have to be retired or a certain age?
The cited parent-housing exception does not set a retirement-age requirement. It also does not specify a minimum distance between the child's home and the parent's home. The lender still needs to verify that the actual housing arrangement meets the exception.
Does adding my income mean my parents are guaranteed approval?
No. When you join as a non-occupying co-borrower, the lender evaluates the borrowers together. Your debts and credit matter as well as your income, and you become jointly responsible for repayment. The property and the full application must also qualify.
