Financing a home for an aging parent or disabled adult child is expensive because lenders normally treat a house you do not occupy as an investment property.
Fannie Mae's Family Opportunity Mortgage lets you finance that home as a principal residence in 2026, subject to specific qualification rules and Massachusetts planning steps.

Determine whether your family qualifies, plan your down payment, and settle the necessary title, tax, and estate questions before you buy.
What Is the Family Opportunity Mortgage?
Yes, you can buy a home for a parent who cannot qualify on their own, or for a disabled adult child, and get owner-occupied mortgage terms even though you will not live there.
"Family Opportunity Mortgage" is the mortgage industry's nickname rather than a branded Fannie Mae product. The actual rule is part of Fannie Mae's occupancy guidelines and treats two specific family housing situations as principal residence purchases.
The nickname refers only to the Fannie Mae conventional rule, so ask your lender how Freddie Mac or FHA loans treat occupancy. When you compare conventional loans in Massachusetts, tell your lender up front that you plan to use the parent or disabled adult child occupancy rule so they underwrite it properly.
Who Qualifies
The rule covers two family relationships, and in both cases the person who will live in the home must be unable to work or lack enough income to qualify for a mortgage alone.
| Situation | Covered? | How the loan is treated |
|---|---|---|
| Adult child buying for a parent who cannot work or cannot qualify alone | Yes | Principal residence |
| Parent or legal guardian buying for a disabled adult child who cannot work or cannot qualify alone | Yes | Principal residence |
| Buying for a parent who could qualify on their own | No | Not eligible under this rule |
| Buying for a grandparent, sibling, in-law, or other relative | Not named in the rule | Ask a lender |
The typical case is a retired parent living on Social Security or a modest pension that cannot carry a Massachusetts mortgage, property taxes, and homeowner's insurance by itself, while the adult child has the income and credit to carry the loan.
If you want to buy for another relative, ask a lender how the purchase would be classified before you make an offer.

Why Owner-Occupied Treatment Matters
Without this occupancy rule, a home you do not live in is classified as either a second home or an investment property, and neither option works well when a parent lives there full-time.
| Loan type | Who lives there | What it means for you |
|---|---|---|
| Principal residence (parent or disabled child rule) | Your parent or disabled adult child; you are treated as the occupant | Owner-occupied terms, as little as 3% to 5% down |
| Second home | You, for part of the year, with exclusive control (one unit) | Does not fit when your parent lives there full-time |
| Investment property | No borrower lives there | Extra risk-based pricing fee, stricter approval, generally a much larger down payment |
Buyers sometimes assume they can call a parent's house a second home on the application. Under Fannie Mae's rules, a second home must be a one-unit property you occupy for part of the year and keep under your exclusive control, so a parent's full-time home does not fit.
An investment property is any home you own but do not occupy. Investment loans carry a loan-level price adjustment (LLPA, an upfront risk fee that affects pricing), must be approved through Fannie Mae's automated underwriting system, and generally require a much larger down payment. The occupancy rule lets you use standard owner-occupied pricing and down payment rules instead.
Down Payment and 2026 Loan Limits
Because a qualifying purchase is treated as a one-unit principal residence, you can put down as little as 3% to 5% depending on your eligibility, though most adult children start at 5%. Confirm your exact loan structure with your lender.
- 5% down: The common starting point for a standard conventional principal residence purchase (95% loan-to-value, or LTV).
- 3% down: Allowed on a one-unit home (97% LTV) if at least one borrower is a first-time homebuyer, or through Fannie Mae's HomeReady program with an income cap of 80% of area median income (AMI).
- Mortgage insurance: Private mortgage insurance (PMI) is required on any conventional loan with less than 20% down.
- Gift funds: Eligible relatives can contribute gift funds toward the down payment or closing costs under Fannie Mae's gift rules.
Because most adult children buying for a parent already own a home, they usually do not meet the first-time buyer rule unless a co-borrower does, and higher earners may exceed HomeReady's 80% AMI cap. For most families, 5% down is the realistic plan.
Your loan must also fit within the conforming loan limits set each year by the Federal Housing Finance Agency (FHFA). For 2026, the baseline one-unit limit is $832,750, up from $806,500 in 2025, with higher limits in some high-cost counties. Check our conforming loan limits in Massachusetts guide and confirm the current figure when you apply.
Qualifying With Two Housing Payments
Even though the new loan gets principal residence terms, you must qualify to carry both your own housing payment and the new one. The underwriter will count three sets of monthly obligations against your income:
- Your current monthly housing payment, including mortgage principal, interest, taxes, insurance, and any condo or HOA fees, or your current rent.
- The full proposed monthly payment on the new home, including principal, interest, property taxes, homeowner's insurance, PMI if applicable, and any condo or HOA fee.
- Your other recurring monthly debts, such as student loans, auto loans, and minimum credit card payments.

What the Lender Will Ask For
Fannie Mae does not list required documents for this occupancy rule, so each lender sets its own checklist. Expect to provide records showing your parent or adult child cannot work or cannot qualify alone, such as Social Security award letters, pension or benefit statements, or tax returns. Ask your loan officer for their checklist early in pre-approval.
Example: Buying a $450,000 Home for a Parent
The figures below are illustrative only; your actual loan amount, down payment, monthly payment, and approval depend on full underwriting.
An adult daughter who owns her own home and has steady W-2 income buys a single-level Cape in Shrewsbury with a first-floor bedroom and full bath for $450,000. Her retired mother lives on Social Security and cannot qualify for a mortgage on her own.
| Item | Example |
|---|---|
| Purchase price | $450,000 |
| Loan treated as | Principal residence |
| Down payment (5%) | $22,500 |
| Loan amount | $427,500 (under the $832,750 baseline limit) |
| Mortgage insurance | Required (under 20% down) |
| Who must qualify | The daughter, carrying her own payment plus the new one and her other debts |
If the daughter met the rules for 3% down, her down payment would be $13,500 instead of $22,500. Beyond the down payment, she also needs cash for closing expenses such as attorney fees, recording fees, title insurance, and prepaids, which you can estimate in our guide to Massachusetts closing costs.

Massachusetts Questions to Settle Before You Buy
How you choose the property and hold title in Massachusetts affects local property taxes, accessibility funding, and long-term care planning.
Title and Senior Property Tax Exemptions
Many Massachusetts cities and towns offer property tax exemptions for older residents, but if you hold title alone, your parent generally will not qualify for senior property tax exemptions. These exemptions generally require the senior resident to both own and occupy the home.
For example, Clause 41C generally requires the senior to be age 70 or older (towns may lower it), have 10 years of Massachusetts domicile, and own and occupy Massachusetts property for at least 5 years, plus meet income and asset limits. Read our Massachusetts senior property tax exemptions guide and confirm rules with the town assessor.
MassHealth and Estate Planning
If your parent wants to contribute cash from selling their previous house or put their name on the deed, that choice can affect MassHealth (Massachusetts Medicaid) long-term care eligibility and your family's estate plan.
Massachusetts also has its own estate tax, with a $2,000,000 exclusion for deaths on or after January 1, 2023. Speak with a Massachusetts elder law or estate planning attorney before a parent gifts funds or before you decide whose name goes on the deed.
Accessibility Upgrades
The Massachusetts Home Modification Loan Program (HMLP), offered through MassAbility (formerly the Massachusetts Rehabilitation Commission) with the Community Economic Development Assistance Corporation (CEDAC), provides no-interest loans for accessibility changes when a household member has a disability or is over age 60. Typical projects include ramps, accessible bathrooms, and widened doorways.
HMLP covers necessary accessibility changes tied to the resident's functional needs, not general repairs such as roofs, general window replacement, heating systems, or septic work. Published sources vary on current dollar caps, so confirm current loan limits and eligibility rules directly with MassAbility or CEDAC.
Choosing the Home
Single-level ranches, ground-floor condos, and Capes with an existing first-floor bedroom and full bathroom make daily life much safer for an aging parent or an adult child with mobility needs. Keep two standard Massachusetts rules in mind as you shop:
- A Title 5 septic inspection is required at property transfer for homes on a private septic system rather than town sewer.
- Homes built before 1978 fall under the Massachusetts lead paint law if a child under six will live in the property.
Other Ways to House a Parent
Depending on where you want to live and how much home equity your parent already has, one of two alternatives may fit better than the Family Opportunity rule.
- Buy a two-family and live in one unit: If you live in one unit and your parent lives in the other, it is a regular owner-occupied purchase and you do not need the rule. A two-unit principal residence allows up to 85% LTV (15% down); see our multifamily mortgage in Massachusetts guide.
- Let your parent buy with a reverse mortgage: If your parent has substantial equity from selling a longtime home and wants to own the next one, ask a specialist whether one of the reverse mortgages in Massachusetts fits better.
Steps to Buy a Home for a Parent or Disabled Adult Child
Following a clear order keeps underwriting and closing on track:
- Confirm your family fits the rule: Make sure your parent or disabled adult child is unable to work or lacks the income to qualify alone, and gather basic benefit or income records such as Social Security award letters.
- Check your budget with both payments: Make sure your income covers your current housing payment, the new payment, and your other monthly debts.
- Get pre-approved with the occupancy rule in mind: Tell your loan officer you are using the parent or disabled adult child occupancy rule. With our team, there is no hard credit pull to start, and pre-approval typically takes 1 to 3 business days once documents are in.
- Shop for a home that fits daily life: Focus on single-level layouts or first-floor bedroom homes, and budget for a Title 5 inspection if the property has a septic system.
- Settle title and estate planning with an attorney: Before closing (typically 30 to 45 days from an accepted offer), review title, gift documentation, MassHealth, and senior tax exemptions with a Massachusetts attorney.
