What the delinquency rate measures
The delinquency rate is the proportion of units in a project whose owners are behind on what they owe the association. It is a plain figure with an unusually direct consequence, because it is one of the very few project characteristics that both government-sponsored enterprises test against a published number.
It matters for two independent reasons, and buyers tend to hear only the first. The obvious one is financing. The less obvious one is that delinquency shifts costs onto the owners who do pay. An association's expenses do not fall because some owners stop contributing; the shortfall is absorbed by a bad-debt allowance in the budget, by drawing on reserves, by deferring maintenance, or by raising assessments on everyone else. A high or rising delinquency rate is a leading indicator of both assessment increases and financing problems, and it usually shows up in the budget before it shows up anywhere else.
Some delinquency is normal. Every association of any size has owners in arrears at any moment, through job loss, probate, dispute, or simple disorganisation. A figure of a few percent is unremarkable and no lender treats it as a finding. What matters is the level relative to the tested line, the trend across several years, and whether the arrears are spread across many units or concentrated in a few.
The agency line: 15 percent, 60 days
The test is stated almost identically by both agencies. Fannie Mae's Full Review requirements, published 5 August 2026, provide that no more than 15 percent of the total units in a project are 60 days or more past due on common expense assessments. Freddie Mac's published guidance provides that no more than 15 percent of the total number of units are 60 or more days delinquent.
Three features of that test are worth reading carefully.
It counts units, not dollars. The measure is the number of units in arrears as a proportion of total units, not the value of the arrears as a proportion of the budget. One large delinquent unit does not move the ratio; a cluster of small ones does. An association reporting its delinquency as a dollar percentage has not answered the question the test asks.
The clock is 60 days. Units 30 days late do not count. A project with widespread short-term lateness and prompt collections can look worse in the ledger than it does under the test.
Special assessments are tested separately. Both agencies apply the same 15 percent, 60-day test to delinquent special assessments as a distinct calculation, not cumulatively with regular assessments. A project at 9 percent on regular assessments and 12 percent on a special assessment passes both tests; adding them to reach 21 percent would be the wrong arithmetic. Where several special assessments are outstanding, each is measured on its own.
One 2026 change alters who this test reaches. On 3 August 2026 Fannie Mae retired its Limited Review and Freddie Mac retired its Streamlined Review. Both abbreviated paths are gone for applications dated on or after that date, so projects that previously cleared without a full financial examination now have their delinquency computed. The requirement did not change; the population it is applied to did.
What delinquency does to the owners who pay
The mechanics are worth understanding, because they explain why lenders care and why a buyer should.
An association's remedies against a delinquent owner run through liens, collection action and ultimately foreclosure, and they are slow and imperfect. The recovery is also capped in a way many buyers do not expect: association assessment liens may have priority over the mortgage only within jurisdiction-specific limits, capped in most jurisdictions at no more than six months of regular common expense assessments. Where a lender forecloses, the association's recovery is bounded. Florida's framework illustrates the pattern: a first mortgagee that acquires title by foreclosure and joined the association in the action is liable for the lesser of the unpaid common expenses accrued in the twelve months before it acquired title, or one percent of the original mortgage debt.
The consequence is that arrears in a building with significant distress are only partly recoverable, and the unrecovered portion is a real cost carried by everyone else. In the budget it appears as a bad-debt or delinquency allowance, and that line is worth reading directly. An allowance that has grown year on year is describing a trend that no single-year delinquency figure captures.
The second-order effect is on reserves. Where cash is short, the reserve contribution is the easiest line to defer, because deferring it has no visible consequence in the year it is deferred. Delinquency is therefore one of the routes by which an association arrives at a low percent funded without ever taking a formal decision to underfund.
What a buyer inherits
Arrears attach to the unit, not only to the person who ran them up. This is the part of the topic where a buyer's exposure is real and where the rules differ most between states.
Assessments generally run with the land and are secured by a lien on the unit. Many state condominium acts make the buyer jointly and severally liable with the seller for assessments unpaid at transfer, and Florida is the explicit example: a unit owner is jointly and severally liable with the previous owner for all unpaid assessments that came due up to the time of transfer of title. The buyer takes the unit exposed to the seller's arrears, has a right of recovery against the previous owner, and cannot require the association to pursue the seller first. That liability does not apply where the association itself acquired title through foreclosure.
The instrument that discovers and caps the exposure is the estoppel or resale certificate. Under the Florida framework the certificate states the current assessment amount and payment status, itemises all outstanding charges and special assessments, and identifies upcoming assessments, and it is binding on the association for 30 days if hand-delivered or emailed and 35 days if mailed. Most states provide an equivalent under a name such as resale certificate or resale disclosure package, with different contents and different binding periods. The certificate is the reason a buyer is not obliged to take the seller's word for the account status, and obtaining it in time for its binding period to cover the closing date is a scheduling question worth raising early.
Whether a particular state imposes successor liability, and how the declaration modifies the default, is a question for a real estate attorney licensed in that state. It is not answerable from a national reference and it is not something a buyer should infer from how it worked in another state.
What people get wrong
Zero delinquency is not the benchmark. Buyers who hear that four percent of units are in arrears sometimes treat it as a finding. It is not. The tested line is 15 percent of units at 60 or more days, and most well-run associations sit far below it. A reference that treats every arrear as a warning gives a buyer no way to tell an ordinary condition from a serious one.
Dollars and units are not interchangeable. A delinquency figure quoted as a percentage of budgeted income is answering a different question from the one the agencies ask. Request the count of units 60 or more days past due, and the total number of units.
Regular and special assessment delinquency are not added together. They are separate calculations against the same 15 percent line. This cuts both ways: a project can pass on both while carrying real distress across two categories, and a project can fail on a special assessment alone while being entirely current on regular dues.
A figure from a questionnaire is a figure from a date. Delinquency moves month to month, and more sharply than most project characteristics. A questionnaire completed six months ago for another buyer's lender is useful evidence of the trend and no evidence at all of the current position. It is the one project test that can change materially between contract and closing.
The seller's arrears are not automatically the seller's problem. The contract allocates cost between buyer and seller; the statute decides who the association can pursue. Those are different questions with different answers, and the association is not bound by the parties' bargain.
What to ask for
Five requests, all answerable from records the association already keeps.
- The number of units 60 or more days past due and the total number of units, as of a stated date, rather than a dollar percentage.
- The same figure for each outstanding special assessment, calculated separately.
- The trend across the last three years, and the bad-debt or delinquency allowance in each of the last three budgets.
- The association's collection policy and whether it is actually being applied, which board minutes will show.
- The estoppel or resale certificate for the specific unit, obtained close enough to closing that its binding period still covers the transfer.
Where the figures sit near the line, the assessment belongs to the lender rather than the buyer, because only the lender computes the test and only the lender knows which review path applies. A buyer cannot check conventional project eligibility independently: Fannie Mae's project tool is restricted to lenders, its status tool is available to associations and their managers rather than to buyers, and Freddie Mac's equivalent is seller-facing. Where the question is what a buyer inherits at closing, that is legal advice, and it belongs to a real estate attorney in the state where the unit sits.
Common questions
What delinquency rate makes a condominium non-warrantable?
More than 15 percent of the total units being 60 or more days past due on common expense assessments. Both Fannie Mae and Freddie Mac apply that line, and both apply the same test separately to delinquent special assessments. The measure counts units rather than dollars.
Is some owner delinquency normal?
Yes. Every association of any size has owners in arrears at any given moment, and a low single-digit figure is unremarkable and not a finding for any lender. What matters is the level relative to the 15 percent line, the direction of travel across several years, and the size of the bad-debt allowance in the budget.
Am I liable for the previous owner's unpaid assessments?
In many states, yes, in part. Assessments generally run with the land and are secured by a lien on the unit, and several state condominium acts make the buyer jointly and severally liable with the seller for assessments unpaid at transfer. Florida does so explicitly, and the association is not required to pursue the seller first. The estoppel or resale certificate is how a buyer discovers and caps that exposure. Whether it applies in a particular state, and how the declaration modifies it, is a question for a real estate attorney there.
Are regular and special assessment delinquencies added together?
No. Both agencies calculate them separately against the same 15 percent, 60-day line, not cumulatively. A project at 9 percent on regular assessments and 12 percent on a special assessment passes both tests. Where more than one special assessment is outstanding, each is measured on its own.
How does a buyer find out the current delinquency rate?
Ask the association or the managing agent for the count of units 60 or more days past due against the total unit count, as of a stated date, and ask separately for each outstanding special assessment. A completed project questionnaire from another buyer's lender is also useful, but it is a snapshot from its own date; delinquency moves faster than most project characteristics and a figure from six months ago proves nothing about today.
Can an association fix a high delinquency rate before closing?
Rarely on a purchase timetable. Unlike a reserve allocation, which a board can change by adopting a revised budget, delinquency is reduced by collection action against individual owners, and lien enforcement and foreclosure take months or years. Recovery is also capped: assessment liens have priority over the mortgage only within jurisdiction-specific limits, in most places no more than six months of regular assessments.
