The Quick Read: Each beach condo is underwritten as its own loan: the lender confirms the building allows nightly rentals, builds a discounted rental income figure for that one unit, and divides it by that unit’s full payment, dues included, while a second or third unit in the same complex adds a building-level concentration question rather than a blended ratio. A DSCR (debt service coverage ratio) loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The building review is where several units in one complex change the file.
- Every unit gets its own ratio. Strong units do not rescue weak ones on a single-property loan.
- Association dues sit in the payment, and beach buildings often carry heavy ones.
- The lender counts a discounted share of projected or reported gross rent, not the full booking number.
- The building’s rental rules and ownership mix are reviewed before income matters.
- Clearing 1.00 is not the same as positive cash flow.
Key Terms Defined
DSCR is the ratio of a property’s qualifying monthly rent to its monthly housing payment. Above 1.00, the rent covers the payment on paper.
PITIA is principal, interest, taxes, insurance, and association dues. It is the payment the rent is measured against.
Qualifying income is the figure the lender actually counts. For short-term rentals, it is a discounted portion of gross bookings.
Warrantable condo is a building that meets standard project-level tests. A non-warrantable condo misses one or more, which is a financing label and not a defect in the building.
Condotel is a building run like a hotel, with a front desk, nightly stays, or a rental program. These are the hardest condo type to place.
Rental pool is an arrangement where owners put units into a shared management and revenue program. A mandatory pool is a major red flag for lenders.
How Does a Lender Walk Through One Beach Condo?
A lender works through six checks in a fixed order: legal use, income figure, discount, per-unit ratio, building review, and exposure. Failing an early check ends the file before the math matters. The order is the part most investors get backwards, because they start with the income number.
Short-term rentals also have their own program terms. Across our wholesale network, a short-term-rental purchase typically reaches up to 75% LTV (loan-to-value, the loan as a share of the property’s value). A short-term-rental refinance or cash-out typically tops out around 70%. A standard long-term rental cash-out is typically held to 75%, so the short-term version is lower. Most programs want a credit score of 640 or higher and about 12 months of hosting or landlord experience. The coverage floor is 1.00 on a purchase and 1.00 on a refinance. All of this is subject to lender guidelines and varies by borrower and property.
Step 1: Is Nightly Renting Allowed in This Building?
Legal use is a gate, not a pricing factor. If the building does not permit nightly stays, the income figure is irrelevant. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
The HOA layer is the one that trips up beach buyers. A building’s declaration is a private contract. It can ban nightly rentals, set minimum stays, cap how many units may be rented, require registration, or force units into a rental pool, even where the city allows short-term rentals. A building that allowed nightly stays in one season may have amended its rules by the next.
Read the declaration before you go under contract, not after the appraisal comes back.
Step 2: How the Income Figure Gets Built
There are three common routes to a short-term rental income figure, and the right one depends on whether the unit has history.
| Income route | Best fit | What the lender leans on |
|---|---|---|
| Trailing 12 months of platform history | Refinance, or a purchase with seller records | Platform statements tied to bank deposits |
| Third-party market projection | Purchase with no history | A revenue report built from comparable listings |
| Appraiser’s short-term rent analysis | Purchase with no history | Appraisal comps and the appraiser’s conclusion |
Refinances usually lean on documented history. Purchases lean on a projection or the appraisal analysis, because the new owner has no statements yet. Lenders differ on which route they prefer, and a few will accept a blend.
The comps matter more than most investors realize. AirDNA’s help center explains that its Rentalizer tool searches comparable listings within a 10-mile radius. It picks them by proximity and by bedroom, bathroom, and guest-count similarity, then uses a weighted average. In a beach complex, that means the best comps are often units in your own building. If the comp set is thin or mismatched, the projection is weak, and a lender will notice.
The revenue basis has limits too. AirDNA’s methodology page says revenue is nightly rates plus cleaning fees, minus discounts and service fees, and that host fees and other additional fees are not included. The headline number you see is not the number a lender will count.
For a deeper look at what lenders accept as proof, see Lendmire’s piece What Counts As Short Term Rental Income For A Lender?.
Step 3: The Discount Between Gross and Qualifying
Lenders do not count gross bookings at face value. They apply a qualifying factor, which is a discount to gross income. The factor varies by program and by file, and it is one of the main places lenders differ from each other.
The reason is simple. The payment excludes operating costs such as cleaning, management, supplies, and platform fees, yet short-term rentals carry all of them. The discount is a rough stand-in for that gap.
Projections tend to run optimistic too. One short-term-rental data vendor reports that its own tests find Rentalizer landing 15% to 30% off actual results, usually on the high side. That is vendor commentary, not an underwriting rule. Still, it explains why lenders prefer history and why a projection built on peak-season comps gets trimmed.
Step 4: The Ratio, Run Unit by Unit
The ratio is qualifying monthly income divided by that unit’s PITIA. Dues go in the denominator. So do insurance and taxes.
This is where beach condos get squeezed. Coastal buildings often carry high association dues and heavy master-policy costs. A unit that looks strong on gross revenue can sag once the full payment is counted. The reverse is rare.
A ratio at or above 1.00 does not mean the unit makes money. DSCR measures rent against the payment only. Vacancy, repairs, furniture replacement, utilities, management, and special assessments all sit outside it. Build your own operating pro forma next to the lender’s ratio.
Step 5: The Building Review (Where “One Complex” Matters)
The lender reviews the project, not just the unit. That usually means a condo questionnaire, the HOA budget and reserves, any litigation, the share of commercial space, the ownership mix, the master insurance, and the rental rules and any pool.
The questionnaire, not the HOA, is how a lender settles the building’s status. HOA managers often cannot say whether a project is warrantable, so lenders ask the specific questions themselves. Ask for the questionnaire early in the contract period.
Non-warrantable does not mean unfinanceable. Many wholesale DSCR programs finance these buildings, usually with tighter leverage or loan-size limits. The causes split into survivable and blocking ones:
| Building issue | Typical lender view |
|---|---|
| Many investor-owned units | Often survivable on DSCR files |
| Thin reserves or high dues | Can limit leverage or require more review |
| Pending structural or safety litigation | Often blocking |
| Deed restrictions on rentals | Often blocking |
| Mandatory rental pool or hotel-style operation | Hard to place, sometimes disqualifying |
Agency rules do not govern these files, but they shape how buildings get labeled. Fannie Mae’s lender letter retired the 50% investment-property concentration limit for established projects under full review, while leaving the presale requirement for new projects in place. That does not settle a DSCR file. As a Michigan community-association law blog notes, individual lenders remain free to keep their own investor-concentration rules. Trade press also reports that agency reserve minimums are rising, from 10% to 15% of budgeted assessment income for full-review applications. Buildings with thin reserves feel that pressure first, and older beach buildings often fit that description.
What Changes When You Own Several Units in One Complex?
Owning several units does not blend them into one ratio. On single-property loans, each unit is its own loan, with its own rent against its own payment. A strong ocean-view unit does not lift a weak garden-level unit sitting in the same building.
What changes is everything around the ratio:
- Investor count. Each unit you buy adds to the building’s share of investor-owned units, which can matter at the project review.
- Leverage and conditions. As your footprint grows, some lenders reduce leverage or add conditions. This varies by lender, and the first unit’s approval does not predict the third’s.
- Lender exposure. Many lenders set their own ceiling on how much they will hold per borrower or per building. That is why investors sometimes split units in one tower across lenders.
- Liquidity. Each loan needs its own down payment, closing costs, and reserves. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA per loan.
- Sequencing. Closing one unit before the next can change the building’s investor mix mid-strategy. Ask each lender about concentration before you contract on another unit.
If you hold units on different bases, one on short-term rent and one on a long-term lease, each is treated on its own basis. Files with every unit on the same basis tend to be cleaner.
A single note instead of several loans
There is one structure that treats units together. A portfolio DSCR loan, also called a blanket or cross-collateralized loan, puts several rentals under one note. The 30-year portfolio DSCR loan covers 2 to 20 properties, and condos are an eligible property type. Coverage is measured on the pool, so stronger properties can offset weaker ones. A unit below 1.00 can sit in the pool only if underwriting tests the pooled coverage, the leverage, and the terms. Building review still applies to each condo, and how short-term income is counted inside a pool varies by lender. Pooled files are reviewed individually, subject to lender guidelines.
A Beach Seasonality Example, in Ratios
These figures are modeled assumptions, not market data. Say a beach unit’s trailing statement shows a strong summer and a soft winter. After the lender’s discount, the annualized monthly income covers the full payment at about 1.20x.
Now stress it. If a weak winter pulls the annualized figure down by roughly a tenth, coverage slides to about 1.08x. If association dues and insurance then push the total payment up by about 10%, coverage drops to roughly 0.98x. Nothing about the building changed. The cushion was just thin.
That is why lenders annualize income rather than qualify on peak months. It is also why a projection built on a summer-weighted comp set deserves suspicion. Run both the base case and the weak-winter case before you offer. For how reserves behave when income swings like this, see Lendmire’s piece How a DSCR Lender Counts Reserves When Short-Term Rental Income Is Seasonal.
If a unit lands under 1.00, programs below that line are available through select lenders in the network, with leverage and terms adjusted. Eligibility depends on the property, the credit profile, and the building.
Where the General Rule Breaks
- Condotel or mandatory rental pool. Hotel-style operations are far harder to place, even in non-QM, and are sometimes disqualifying.
- Investor-heavy but clean building. Often workable, since ownership mix is rarely the deciding factor on a DSCR file. Pending safety litigation and deed restrictions are much harder.
- No operating history on purchase. The file rests on the appraisal analysis or a projection. Weak comps and peak-season assumptions are the usual failure points.
- Special assessments. The ratio never sees them. Thin reserves in an older beach building can trigger a large one after closing.
- Same-building comps. If the only comps are neighboring units, one unusual unit, such as a renovated penthouse, can skew the whole set.
- Insurance shifts. Coastal master-policy costs flow into dues. A renewal after your ratio was run can change the picture.
A closing note on cash flow: tax treatment varies, and investors should consult a qualified professional before relying on any deduction.
What the Investor Decision Looks Like
The practical order runs like this:
1. Read the declaration and confirm nightly rentals are allowed for that unit.
2. Request the condo questionnaire and the HOA budget and reserve figures.
3. Decide the income route: history, projection, or appraisal analysis.
4. Test the ratio with the full payment, dues included, in a base case and a weak-season case.
5. Before a second unit, ask the lender how many units it will hold in that building.
6. Build a separate operating pro forma, because the ratio is not a profit measure.
Across our wholesale network, files that stall tend to stall at steps one and two, not at the math. Lenders vary widely on building concentration, so a no from one lender is not always a no from another.

Frequently Asked Questions
Does owning three units in one complex combine them into one DSCR?
No. On single-property loans, each unit has its own ratio against its own payment. The combined exposure shows up at the building review and in each lender’s own limits. A portfolio loan is the exception, since it measures coverage on the pool.
Can the HOA tell me if the building is warrantable?
Usually not. The lender’s condo questionnaire answers that question, so ask for it early. The HOA can still tell you the rental rules, which you must confirm separately.
Does my city allowing short-term rentals mean the building allows them?
Not necessarily. HOA declarations are private contracts that operate separately from city rules. A building can ban or limit nightly stays even where the city permits them.
Does lender qualifying income match the number on a market report?
Usually not. Lenders count a discounted share of projected or reported gross income, and the discount varies by program. The report’s own revenue basis also leaves out some fees.
What leverage can a short-term-rental condo reach?
On a short-term-rental purchase, programs typically go up to 75% LTV, and a short-term-rental refinance or cash-out typically tops out around 70%. A building that is non-warrantable may see tighter leverage, subject to lender guidelines.
