The Quick Read: Usually, yes, on the income test. A Nantucket rental qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and your personal income is not the deciding factor. Credit, reserves, an appraisal, legal rental use, and carrying costs still apply, so rent alone clears one test, not the whole file.
- DSCR compares documented rent to the full monthly housing payment (PITIA).
- For select programs, a 1.00 ratio is the floor, and stronger ratios open better terms.
- Short-term rental (STR) income needs proof: history, a market projection, or appraisal rent.
- Island insurance and flood costs sit in the payment and can pull the ratio down.
- Local registration must be in order before a lender will lean on STR income.
What Does “Rent Alone” Actually Mean?
The lender asks whether the property’s documented rent covers its own payment. It does not ask for your traditional personal-income documentation to prove you can afford it.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
The rest of the file still counts. Most programs we place files with want a credit score around 660, though a 620 floor exists in parts of the network and 700+ unlocks the strongest leverage. You also need reserves, commonly around 6 months of PITIA, stepping up to about 9 months above $1,500,000. On Nantucket, many purchases cross that line.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. A house you plan to live in all summer is a poor fit. A house you buy to rent is the fit.
For the full program picture, see the complete DSCR loans guide.
How Is the Ratio Calculated?
Divide qualifying monthly rent by the full monthly housing payment. That payment is PITIA: principal, interest, taxes, insurance, and any association dues. A result above 1.00 means rent covers the payment on paper.
Here is the catch. Clearing 1.00 is not the same as positive cash flow. The ratio ignores repairs, vacancy, management, utilities, and capital costs. A Nantucket house can clear 1.00 and still lose money in a bad season.
Purchase leverage on most files lands at 75%–80% LTV on an investment-property purchase, so you put roughly 20%–25% down. LTV means loan-to-value, the loan as a share of the property’s value. A larger down payment lowers the payment and can lift the ratio. It never erases credit floors, reserve rules, or property eligibility.
Why Does Nantucket Math Look Different?
Nantucket is a seasonal, high-priced, high-carry market. Strong summer income has to be spread across twelve months, and weak shoulder-season months pull the annual average down. A high nightly rate times 30 is never the coverage figure.
High prices matter too. When the price is large and rent is merely good, the payment can outrun the income, and coverage lands thin even in a busy resort. Insurance adds to it. The MV Times quotes a state official saying Islanders and Cape Codders pay about 40% more for home insurance than the state average. Because insurance is in PITIA, higher premiums lower the ratio directly. Flood coverage is separate, since standard homeowners policies exclude flood, and a flood-zone property needs its own policy.
(Run the ratio before you bid, not after. Island carrying costs have a way of surprising people.)
Which Rent Figure Counts?
The lender, not you, decides which rent figure counts. Treatment varies from lender to lender, and no agency governs how DSCR lenders count STR income. Across our network, the evidence usually comes in three forms:
| Income route | Best for | What supports it |
|---|---|---|
| Actual platform history | Refinance, or a purchase with hosting record | About 12 months of statements, matched to deposits |
| Market-data projection | Purchase with no history | Third-party rental analysis |
| Appraisal rent | Conservative fallback | Market rent schedule |
The appraisal form matters. The 1007 is the single-family rent schedule, and the 1025 covers 2–4 unit small income properties. Appraisal rent reflects long-term market rent, so it usually understates a resort STR. That is why STR files lean on history or a projection instead.
Lenders also trim gross STR income before dividing. A trim of roughly 20%–25% is a common range, and that range is a habit, not a rule. A gross ratio that looks like 2.0x can drop to about 1.60x after a 20% trim. Treat that as an illustration of the effect only.
STR program terms in our network run differently from long-term-rental terms. On a purchase, STR leverage tops out at 75% LTV. Refinances sit around 70%, and cash-out on STR collateral is 70%. Expect a 640+ score and about 12 months of hosting history. Coverage floors start at 1.00 on purchases and refinances. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Is the Rental Legal? A Nantucket Checklist
A lender wants the STR use to be lawful, and Nantucket shows what that looks like. 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. Nantucket is the example, not a national rule.
The Town of Nantucket requires STR certificates to be renewed annually. Renewal calls for an attestation of prior-year compliance and proof of a liability insurance policy. The Town’s FAQ adds that each dwelling unit needs its own certificate, and stays of more than 31 days are not treated as STRs.
On the state side, the Massachusetts Department of Revenue applies a 5.7% room occupancy excise to stays of 31 days or fewer. Towns may add a community impact fee of up to 3% for multi-property operators. The town’s Chapter 338 regulation also requires operators to keep income records and proof of remitted occupancy tax. That page is several years old, so confirm the current text.
A quick pre-application checklist:
- Confirm the town and state registration is current for this exact unit.
- Confirm the income records match what you plan to submit.
- Confirm insurance, including flood where required.
- Check any association rules.
An owner who rents 14 days or fewer a year falls outside the Nantucket STR definition. That is a personal-use pattern, not an income pattern, so it will not support DSCR income.
What About Guest Cottages and Duplexes?
A second unit can add real rent. A duplex or a main house plus a legal cottage may carry a payment more comfortably than a single house, because two rents share one payment. Whether an accessory unit counts depends on whether it is legally separate and rentable, and on how the appraiser treats it.
Each dwelling needs its own certificate for STR use. An unpermitted cottage adds risk, not income. Documented, legal units are what a lender can count.
Some property types are simply out. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs.
What Happens When Rent Falls Short?
Rent that does not cover the payment does not end the conversation. It changes the structure. Consider the options in rough order:
1. Lower the leverage. More down shrinks the payment and lifts the ratio.
2. Re-run the income route. A documented STR history or projection may beat appraisal rent, or the reverse, depending on the lender.
3. Add a legal unit. A second rentable unit adds income to the same payment.
4. Look at sub-1.00 options. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
5. Look at structure. Extended terms (40-year) and interest-only periods are available through select lenders in the network. The spine is the 30-year fixed, and above $2,500,000 the network generally holds to 30-year fixed structures.
6. Consider a different path. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Loan sizes run up to $3,000,000 on standard programs. Many island purchases exceed that, and those files may not fit a standard program at all.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What Else Does the Lender Review?
Beyond rent, expect a review of credit, reserves, the appraisal, the borrower’s entity, and the property’s eligibility. An LLC can hold title, subject to lender program eligibility. Each file is underwritten individually, and programs change.
Refinances work a little differently. With a hosting record, the history route applies, and platform statements are reconciled against deposits. Cash-out on a standard rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Tax treatment varies; consult a qualified professional.

LTV: loan-to-value, the loan amount as a percentage of the property’s value.
1007 / 1025: the appraisal forms for market rent on a single-family home and on a 2–4 unit property.
Seasoning: the waiting period a lender wants after you acquire a property before certain refinances.
Frequently Asked Questions
Do I need tax returns or W-2s for a Nantucket DSCR loan?
Usually not as the deciding factor. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. You still provide credit, assets for reserves, and entity documents.
Can I use the house myself during the summer?
Not as an owner-occupied home. DSCR loans are for investment property, so personal-use patterns do not support the income. Light personal use is something to raise with the lender before you apply.
Can I qualify on a purchase with no rental history?
Often, yes, through an appraisal rent figure or a market-data projection. Lenders differ on how much weight they give a projection. Select STR programs in the network expect about 12 months of hosting history, so confirm which route applies.
Does high insurance and flood cost really matter if rent is strong?
Yes. Insurance and taxes are in the payment, so higher premiums lower the ratio directly. A flood policy adds to it where required.
What if the ratio comes out below 1.00?
Select lenders in the network offer coverage below 1.00, with leverage and terms adjusted. Lower leverage or a second rentable unit may also bring the ratio up.
