Below-Market-Rate Housing Works
Below-Market-Rate Housing Units are rental apartments or homes for sale whose rent or purchase price is restricted under a government housing program, recorded affordability agreement, or other binding rule. They are usually reserved for households that meet income, household-size, occupancy, and documentation requirements. A BMR unit is not free housing, and “below market” does not mean the same rent, price, or eligibility standard in every city.
A below-market-rate unit costs less than a comparable unrestricted market-rate home because a public agency or affordability agreement limits what the owner may charge or receive. In exchange, the tenant or buyer must qualify under program rules. Rental BMR units commonly have restricted rents and income certification. Ownership BMR units commonly have restricted purchase prices, owner-occupancy requirements, and limits on future resale.
What Are Below-Market-Rate Housing Units?
Below-Market-Rate Housing Units, often shortened to BMR units, are homes that cannot be rented or sold at the full price the open market might otherwise support. Their affordability is created and enforced through a local housing program, deed restriction, regulatory agreement, recorded covenant, development condition, or similar legal control.
The phrase describes the pricing and restriction attached to the home. It does not identify one nationwide benefit. A city may use BMR housing as part of an inclusionary housing program, an affordable homeownership program, a public-land agreement, or another local housing policy. Our national guide to Inclusionary Housing in the United States explains the broader system that often produces these units.
Other official listings may use related terms such as:
- Income-restricted housing: Occupancy is limited to households within stated income limits.
- Deed-restricted affordable housing: A recorded document limits rent, sale price, occupancy, or resale.
- Price-restricted home: The purchase and future resale price are controlled by a program formula.
- Affordable dwelling unit: A local term for a regulated rental or ownership unit.
- Inclusionary unit: A home created through an inclusionary housing or zoning requirement.
These terms can overlap, but they are not automatically interchangeable. The property listing and controlling program documents determine the actual rules.
How a BMR Unit Differs From a Market-Rate Unit
A market-rate home is generally offered at a price negotiated in the open rental or sales market, subject to applicable housing law. A BMR home has an additional affordability restriction that limits price and usually limits who may occupy or purchase it.
- Rent or sale price: Market-rate pricing responds primarily to market conditions. BMR pricing follows a program rule, affordability schedule, or approved formula.
- Applicant income: A market-rate property may screen whether a household can afford the home, but a BMR program also applies a maximum income limit and may apply a minimum-income rule.
- Household eligibility: BMR programs may regulate household size, primary-residence use, property ownership, assets, or buyer status.
- Ongoing restrictions: A BMR rental may remain subject to rent and tenant-certification controls. A BMR ownership home may remain subject to resale, refinancing, and owner-occupancy restrictions.
- Future price growth: An unrestricted owner may generally sell at the market price. A BMR owner normally must use the resale process and maximum price permitted by the recorded agreement.
The physical apartment or condominium may be similar to a market-rate unit in the same development. The major difference is the legal and financial restriction attached to the home, not necessarily its appearance.
Below-Market-Rate Rental Housing
A BMR rental is an apartment with a maximum rent or rent-setting method established by the local program. The unit is leased to a household that meets the required income and occupancy standards. Depending on the jurisdiction and property documents, the tenant may need to complete income certification before moving in and recertification during the tenancy.
Common features of below-market rentals include:
- Restricted rent: The landlord cannot simply charge the same unrestricted rent as a comparable market-rate apartment.
- Income qualification: The household must fit the income tier assigned to the unit.
- Occupancy requirement: The apartment must usually be the household’s primary residence.
- Household-size rules: The household may need to fit the permitted occupancy range for the bedroom size.
- Tenant certification: The owner, marketing agent, or housing agency may verify wages, benefits, assets, household members, and other required information.
- Program monitoring: The housing agency may monitor rent, tenant eligibility, leases, and compliance records.
A restricted rent is not necessarily based on the tenant’s exact monthly income. Some BMR rentals use a rent established for the unit’s AMI tier, while other affordable programs use different rent methods. Always read the property-specific listing rather than assuming that every affordable tenant pays the same percentage of income.
Below-Market-Rate Homeownership
A BMR ownership unit is sold at a restricted price to an eligible buyer. The lower initial price is paired with long-term controls designed to preserve the home as an affordable ownership opportunity for future buyers.
Common buyer requirements may include:
- Income eligibility: Household income must remain within the program’s limit for the property.
- Homebuyer education: The buyer may need to complete an approved course.
- Mortgage qualification: The buyer must obtain financing that complies with the program and lender requirements.
- Buyer funds: The household may need verified funds for a down payment, closing costs, reserves, inspections, or other expenses.
- Primary residence: The approved household must occupy the home as required by the BMR agreement.
- Property-ownership limits: Some programs require first-time homebuyer status or restrict ownership of another residence.

How BMR Rents and Purchase Prices Are Restricted
There is no single national BMR rent or sales-price formula. Local rules may consider the unit’s AMI tier, bedroom size, assumed household size, utility allowance, mortgage costs, interest rates, association dues, taxes, insurance, or other program factors.
For rentals, the program may publish a maximum allowable rent or require the owner to obtain approval before setting or changing the rent. Tenant-paid utilities may reduce the maximum amount charged as base rent when the local method includes a utility allowance.
For ownership homes, the initial affordable price may be established when the unit enters the program. A future maximum resale price may then be calculated under a recorded formula rather than the unrestricted market value. The permitted price can depend on the original price, an index, approved improvements, depreciation, transaction costs, or another locally adopted method.
Because the controlling formulas differ, a price described as “below market” should not be evaluated by comparing it only with nearby online listings. The buyer must review the official price, association costs, property condition, financing terms, and recorded restrictions together.
Income Certification and AMI Requirements
Most Below-Market-Rate Housing Units are assigned to households within one or more income bands. Programs commonly express those bands as a percentage of Area Median Income, or AMI. The applicable dollar limit changes by location, household size, effective year, and sometimes the specific funding or program layer.
Use our detailed guide to how Area Median Income affects affordable housing eligibility when reading percentages such as 50%, 80%, 100%, or 120% AMI. This BMR definition page does not publish one national income table because no single table controls every property.
Income certification may require the program to review:
- Employment income: Wages, salaries, overtime, bonuses, commissions, and tips when required.
- Self-employment: Business income, tax records, statements, and supporting evidence.
- Benefits and support: Social Security, pensions, unemployment benefits, support payments, or other recurring income.
- Assets: Bank accounts, investments, real estate interests, and income produced by assets under the applicable rules.
- Household members: The people who will occupy the unit and whose income must be counted.
A household may be over the maximum income limit or, for some units, below the minimum income needed to support the rent or mortgage. A voucher or other approved subsidy may change how a minimum-income requirement is applied, but the project rules control.
Occupancy and Primary-Residence Rules
BMR housing is generally intended for the eligible household’s actual residence, not as an investment, vacation property, or unrestricted rental business. The lease, deed restriction, or program agreement may require the approved household to occupy the home for a stated portion of the year.
Occupancy rules may address:
- Bedroom size: A program may set minimum or maximum household sizes for a studio, one-bedroom, two-bedroom, or larger home.
- Household changes: Birth, marriage, separation, departure, or another change may need to be reported.
- Subleasing: Renting out all or part of a BMR home may be restricted or prohibited without approval.
- Owner occupancy: A BMR buyer may need to occupy the home continuously as a primary residence.
- Other property ownership: The household may be restricted from owning or occupying another residence.

Resale Restrictions and Shared-Equity Rules
The most important difference between BMR ownership and unrestricted ownership often appears when the home is sold. A BMR owner usually cannot place the property on the open market at any price and sell it to any buyer.
The recorded restrictions may require the owner to:
- Notify the administering agency: The city or program may need advance notice before marketing begins.
- Use an approved resale price: The maximum price is calculated under the program’s formula.
- Sell to an eligible buyer: The next household may need income, asset, occupancy, and first-time-buyer approval.
- Follow an approved marketing process: A lottery, agent process, waiting list, or agency review may apply.
- Obtain approval before closing: The agency may review the buyer, financing, contract, and closing documents.
Some affordable ownership programs are described as shared-equity housing because the homeowner receives part of the home’s appreciation while the affordability mechanism preserves value for the next buyer. The exact equity split or resale formula is not universal. It must be taken from the deed restriction or program agreement for that home.
How Long a BMR Restriction Lasts
An affordability period is the length of time that the rent, sale price, occupancy, or resale controls remain effective. The period can vary widely. Some restrictions last for a stated number of years, while others are designed to remain for the life of the project or continue through repeated resales.
A restriction does not disappear merely because the original tenant moves or the first owner sells. The agreement may bind later owners and occupants until the stated affordability term ends. Buyers should review the recorded covenant and closing documents before assuming that the home will ever convert to unrestricted market-rate ownership.
Why BMR Does Not Mean Free Housing
Below-Market-Rate Housing Units reduce rent or purchase price under a program, but they still carry real housing costs and obligations.
- Renters: May pay monthly rent, a lawful security deposit, tenant-paid utilities, insurance, and optional charges.
- Buyers: May pay a down payment, mortgage, closing costs, property taxes, homeowners insurance, association dues, repairs, assessments, and maintenance.
- Both renters and buyers: Must comply with the lease, occupancy rules, certifications, notices, and other program requirements.
“Below market” means restricted below an unrestricted market level under the applicable program. It does not mean that the unit is free, deeply subsidized, affordable to every income level, or exempt from ordinary tenant or homeowner responsibilities.
Are BMR Units the Same as Section 8?
No. A BMR unit is a price-restricted or income-restricted home. Section 8 generally refers to rental assistance that helps an eligible household pay rent. The two mechanisms can sometimes interact, but they are not the same program and do not use the same rent or application rules.

How to Recognize a BMR Listing
A legitimate BMR listing should identify the administering program, the property, and the restrictions that apply. Before submitting personal information, check for:
- Official program name: The city, county, housing agency, or approved affordable housing program.
- Exact address and unit: The building, bedroom size, and whether the opportunity is rental or ownership.
- Restricted cost: The monthly rent or purchase price and any listed utility or association costs.
- Income tier: The AMI level and household-size limits.
- Application status: Open, closed, waitlist, first come, or another official status.
- Application route: The approved portal, paper process, or marketing agent.
- Restrictions: Occupancy, certification, resale, or other continuing requirements.
Do not assume that an advertisement using the words “affordable” or “below market” is part of an official BMR program. Verify the opportunity through the named public agency or approved portal.
Where to Find Current BMR Opportunities
This definition page does not list live projects because availability, prices, and deadlines change. Current opportunities belong on city hubs and permanent property pages.
San Francisco commonly uses the BMR label for income-restricted rentals and affordable ownership homes. Buyers can review open San Francisco BMR homes for sale on DAHLIA for verified current ownership listings. Other cities may use different terms and application systems.
Common BMR Misunderstandings
- “BMR means anyone can apply.” The applicant must meet the listing’s income, household, occupancy, and other eligibility rules.
- “Every BMR rent is based on 30% of my income.” The unit may use a published restricted rent rather than a tenant-specific rent formula.
- “A BMR buyer can later sell at full market value.” Recorded resale restrictions commonly limit the future price and eligible buyer.
- “Below market means poor quality.” BMR describes pricing and legal restrictions, not a universal construction or condition standard.
- “A low purchase price guarantees affordable ownership.” Mortgage costs, association dues, taxes, insurance, repairs, and assessments still matter.
- “A BMR unit is automatically Section 8 housing.” A restricted unit and rental assistance are separate mechanisms.
- “Rules are the same nationwide.” Local ordinances and property agreements control the actual requirements.
Understand the Restriction Before You Apply
Below-Market-Rate Housing Units are legally or contractually restricted rental and ownership homes offered below unrestricted market pricing to qualified households. Renters should confirm rent, utilities, income certification, occupancy, and recertification rules. Buyers should confirm financing, owner occupancy, resale price, shared-equity terms, and the affordability period. The safest next step is to read the official property listing and controlling program documents rather than relying on the BMR label alone.
