HOA Fees Explained: Dues, Reserves and Special Assessments

HOA dues are the monthly or annual charge you pay a homeowners or condominium association to run and maintain shared property. They’re a real housing cost: lenders add them to your monthly housing expense when deciding how much you can borrow, so $300 a month in dues can reduce your price range about as much as $300 of extra mortgage payment. Before buying, check two things beyond the dues amount: whether the association is saving enough for future repairs, and whether a special assessment is coming.

What HOA dues pay for

Every association sets its own budget, so what’s covered varies. A single-family subdivision might charge modest dues for a pool, landscaping and common-area insurance. A condo building’s dues often cover far more.

The master policy matters. If it covers only the building’s shell, you need a policy that covers interior walls, fixtures and improvements as well as your belongings. Our guide to what homeowners insurance covers explains the coverage parts. HOA dues are usually paid directly to the association, not through your mortgage escrow account.

Reserves and reserve studies

A healthy association budget has two parts: operating expenses for this year, and contributions to a reserve fund for big, predictable replacements such as roofs, paving, elevators, boilers and siding.

A reserve study is the planning document behind that fund. A specialist inventories the shared components, estimates their remaining life and replacement cost, and sets out a long-term funding plan, usually looking 20 to 30 years ahead. It’s the association-sized version of the sinking fund approach to home maintenance.

Two signs of underfunding:

• Low annual contributions. Fannie Mae’s project standards include a budget test: for condo projects that get a full lender review, the association’s budget should set aside at least 10% of its assessment income for replacement reserves, unless a qualifying reserve study shows the project is adequately funded. A lower figure doesn’t prove trouble, but it’s a reason to ask questions.
• An old or missing study. A study done a decade ago may not reflect today’s construction costs.

Some states now require reserve studies. After the 2021 condominium collapse in Surfside, Florida passed a law requiring structural integrity reserve studies for condo and co-op buildings three stories or taller, repeated at least every 10 years, and ended associations’ ability to waive reserves for those structural items. It has adjusted the details and deadlines since. Rules vary by state, so ask what applies where you’re buying.

Special assessments

A special assessment is a one-time charge billed to owners when the association needs money it doesn’t have, usually because reserves fall short of a major repair or because of an uninsured loss or lawsuit. It can be due as a lump sum or spread over months or years, and how it’s approved and allocated depends on state law and the association’s governing documents.

Special assessments are a major reason to read the financials before you buy. If one has been approved but not yet billed, the purchase contract should spell out whether the seller or the buyer pays it.

How HOA dues affect your mortgage

Fannie Mae’s Selling Guide counts owners’ association dues as part of the monthly housing expense used to calculate your debt-to-income ratio, alongside principal, interest, taxes and insurance. Lenders convert annual or quarterly dues into a monthly figure. Special assessments you’re paying can also count.

That means every dollar of dues uses up borrowing capacity. At an illustrative 6.5% rate on a 30-year loan, $300 a month is roughly the principal-and-interest payment on a $47,500 loan. Our how much house can I afford guide walks through the ratios.

For condos, the lender also reviews the project itself, often with a questionnaire the association completes. Fannie Mae’s and Freddie Mac’s forms ask about reserves, special assessments, pending litigation and the condition of the building. A project with problems can be ineligible for a conventional loan, even if you qualify personally.

Worked example: two condos at the same price

A buyer earning $90,000 a year ($7,500 a month) with a $400 car payment compares two $300,000 condos. Both are bought with 20% down and a $240,000 loan at 6.5% for 30 years (rates are illustrative). Property tax is 1.1% a year and the condo insurance policy is $600 a year.

Condo A sits comfortably under the traditional 28% and 36% benchmarks. Condo B is over 28% on housing and just under 36% in total. Many loan programs allow higher ratios, but the $300 difference in dues shrinks the buyer’s margin.

Now suppose Condo B’s 80-unit association collects $480,000 a year in assessments and budgets $36,000 for reserves. That’s 7.5% of assessment income, below the 10% budget test. Its reserve study calls for a $1.2 million roof and facade project, and the reserve fund holds $450,000. If the $750,000 shortfall were split evenly, each owner would owe a special assessment of $9,375. (Actual shares follow the governing documents, often by unit size or ownership percentage.) The higher dues don’t guarantee a well-funded association.

Documents to request before you buy

Ask the seller, the association or the management company for these, and read them during your contract’s review period:

• Current budget and most recent financial statements, including the reserve balance.
• Reserve study, with its date and the recommended contribution compared with what’s actually budgeted.
• Disclosure of any approved or proposed special assessments.
• Board meeting minutes for the last 12 to 24 months. Planned repairs and disputes show up here first.
• Governing documents: declaration (CC&Rs), bylaws, and rules, including rental and pet limits.
• Master insurance policy summary, showing what the association insures and the deductible.
• Pending litigation involving the association.
• Resale certificate or estoppel letter, which many states require, confirming the seller’s account is current.
• Recent building inspection reports, especially for older high-rise condos.

If dues have risen sharply, reserves look thin, or minutes mention a big repair without a funding plan, ask your agent and lender before you go further. Confirm current dues and any assessments in writing before closing, and make sure they appear in your loan file.
