The Quick Read: A DSCR loan is reviewed for the property’s rent against its full monthly housing payment, not your personal paycheck. In the U.P., the harder question is usually whether the short-term rental is allowed at that address, not whether the income number clears. Marquette, the Pictured Rocks gateway towns, and Mackinac Island each answer that question differently. Check it before you write an offer.
Key Takeaways
- DSCR (debt service coverage ratio) is rental income divided by the full monthly payment. It says nothing about repairs, vacancy, or profit.
- On short-term rental (STR) collateral, purchase leverage tops out at 75% LTV on the strongest files. Cash-out and refinance top out around 70%.
- STR files typically expect a 640+ credit score and about 12 months of host or landlord experience.
- Lenders use the lower of two income figures when both exist, and they discount market-data projections.
- Permit rules decide whether STR income counts at all. They differ between Marquette, Munising, and Mackinac Island.
How DSCR Loans Work in Michigan’s Upper Peninsula
A DSCR loan treats the property as the borrower. The lender asks one question: does the rent cover the payment? The ratio is gross rental income divided by PITIA, which is principal, interest, taxes, insurance, and any HOA dues.

As of Oct 1, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Rent, nightly rate, occupancy, taxes, and insurance are editable estimates. 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.
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. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. You still document the property, the entity, and your reserves. What drops away is the personal-income paperwork.
Lendmire is a mortgage broker. It arranges these loans through a wholesale network of DSCR lenders across 41 markets, including Washington, D.C. The lenders review eligibility and approve. The broker’s job is matching your file to the program that fits.
One thing trips up first-timers. A ratio above 1.00 is not “positive cash flow.” DSCR compares rent to PITIA and nothing else. Repairs, vacancy, snow removal, management, utilities, and capital reserves all sit outside it. A cabin can clear coverage and still lose money in a slow shoulder season.
For the full mechanics, see Lendmire’s complete DSCR loans guide. This article covers what changes when the property is a vacation rental in a small, seasonal, permit-sensitive region.
Why the U.P. Is a Real STR Test Case
The U.P. Has genuine visitor demand. The National Park Service reports that 910,939 visitors to Pictured Rocks spent $45,770,000 in nearby communities, supporting 544 local jobs. An earlier NPS release put annual visitation at 575,451. That is strong growth. It is also a reminder that visitor-driven markets move unevenly.
Demand is the easy half. The hard half is that three markets can sit a short drive apart and carry three different rule sets. Here is how each one shapes a loan file.
| Market | Main underwriting question | Likely income basis |
|---|---|---|
| Marquette | Does the property hold a transferable permit? | STR if permitted, else long-term rent |
| Munising / Pictured Rocks | Which jurisdiction is the parcel in? | STR if permitted, else long-term rent |
| Mackinac Island | Are nightly stays allowed at all? | Likely long-term or 30-day-plus rent until confirmed |
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. That one sentence carries a lot of weight in this region.
Step by Step: How an STR File Gets Underwritten
The sequence is the same across most lenders. The details are where files live or die.
Step 1: Pick the income basis. For a short-term rental, programs in the network qualify on market-data projections, such as AirDNA revenue estimates, or on historical STR income. For a long-term rental (LTR), they use a lease or an appraiser’s market-rent opinion.
Step 2: Choose the appraisal form. Form 1007 is the appraiser’s rent schedule for single-family homes. Form 1025 covers 2-4 units and gives a separate rent opinion for each unit. Here is the catch: Form 1007 was built for monthly leases. It does not measure Airbnb income. Turning a nightly price into a monthly figure and dropping it into that form is the wrong method. An STR normally needs its own income analysis, often delivered as an addendum to the appraisal.
Step 3: Apply the lower-of convention. If a lease-style appraisal figure and a market-data projection both exist, most programs use the smaller one. A glowing projection does not automatically win.
Step 4: Apply the discount. Most programs haircut market-data projections before using them. The lender is protecting itself from optimistic modeling.
Step 5: Compute the ratio. Gross qualifying income divided by PITIA gives the DSCR. On STR collateral, the purchase floor is 1.00, and the refinance floor is also 1.00. Stronger ratios open better pricing and leverage.
Step 6: Match, appraise, underwrite. The broker shops the scenario across the network, matches lender, product, and tier to your profile, and the deal works to appraisal and underwriting.
Where U.P. Income Numbers Get Shaky
Three things make U.P. Files harder than a big-metro vacation market.
Thin comps. Towns like Munising, Grand Marais, and Mackinac Island have few comparable rentals. Fewer comps mean a wider range of estimates. Two data providers can land far apart on the same cabin.
Seasonality. In the U.P., demand concentrates in summer and fall. Market-data models tend to average the year. A property that earns most of its money in a few months can look better on paper than it feels in a January bank balance.
Illustrative market data. AirDNA’s Marquette page shows Airbnb and Vrbo listings averaging 57% occupancy and a $248 average daily rate. Treat that as a sample of what an income report is built from, not a forecast for your address.
An operator-level observation: in markets like this one, the files that run smoothly tend to carry two numbers from day one. One is the STR projection. The other is the long-term-rent fallback. Because of the lower-of convention, the fallback is often the binding figure. Investors who only modeled the exciting number get surprised at appraisal.
Marquette: Capped Permits, Real Premiums
Marquette is the clearest case of legality driving financeability. WLUC reported that the city’s permits are all accounted for and that a waitlist exists. Marquette Township, by contrast, has no cap, with fewer than 20 permits issued.
The practical consequence for a buyer is simple. A house that already holds a valid permit may carry a premium. A house with no permit may not be able to operate as an STR at all. An AirDNA projection for an unpermitted house is not defensible income.
Whether a permit transfers on sale is something to confirm with the city before you go under contract. Do not assume it. Getting that answer in writing early can save a file.
Picture a buyer eyeing a Marquette house with a transferable permit. Run the numbers on modeled assumptions: the discounted STR projection covers the payment at roughly 1.3x, while long-term rent alone covers it at about 0.95x. The lender takes the lower figure. That puts the file in sub-1.00 territory. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. A larger down payment helps the ratio, but it does not erase credit floors, reserve rules, or property eligibility.
The same file in the township, where an operator can hold a permit, might be a cleaner STR story. Different jurisdiction, different file.
Munising and Pictured Rocks: Know Which Jurisdiction You’re In
Pictured Rocks drives the demand. The jurisdiction drives the loan. Two neighboring governments can treat the same view very differently.
The City of Munising’s ordinance makes STRs a conditional use by permit in certain districts. It prohibits signs advertising a property as an STR, and it ties violations to possible permit revocation. Munising Township is a separate jurisdiction with its own zoning, including a buffer zone tied to the park. Gateway towns around Pictured Rocks have also changed their permit rules over time.
So the parcel’s exact municipality matters more than the mailing address. Ask the zoning office which body governs the property, then ask what permit it needs.
A permit that can be revoked is a risk on the income side of the ratio. Lenders know this. Expect them to look hard at permit status and to lean on the long-term-rent fallback when the paper trail is thin.
A property-type note for Pictured Rocks buyers: cabins are everywhere in the U.P. Log homes, manufactured homes (single- and double-wide), and barndominiums are not offered in the network’s DSCR programs. They fall outside these programs. A “log cabin” listing that looked perfect on a trail map may never reach an underwriter.
Mackinac Island: Verify Legality First
Mackinac Island is the market where investors assume the most and can confirm the least. Sources conflict. Some local planning materials point toward restricting short-term rentals under the island’s hotel definition, and some rental-management sites cite 30-day minimum stays. I have not found verified, adopted ordinance text.
So don’t assert an island rule, and don’t let a seller’s listing do it for you. If nightly rentals are barred or minimum stays apply, an AirDNA-style nightly income basis does not fit. The file becomes a long-term or 30-day-plus rental, underwritten on rent.
Mackinac is also a small, seasonal market with thin comps. Many island rentals are inn-style or room rentals, which are a different asset from a whole-house STR. Treat nightly income as unproven until the municipality confirms it in writing. Then model the fallback.
Michigan state law adds uncertainty. Proposals to limit local STR bans have surfaced over the years, as the Mackinac Center has described. This is an advocacy source, and I could not confirm what became law. Don’t plan around statewide preemption.
What the Network Lets You Borrow on STR Collateral
These are typical ranges from select lenders in Lendmire’s wholesale network. They are not commitments to lend, and every file is underwritten individually.
DSCR vs. conventional financing
There are two common ways to finance an investment property in this market, 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.
- Purchase: up to 75% LTV on the strongest files, with LTV (loan-to-value) meaning the loan as a percentage of the property’s value.
- Refinance and cash-out: on STR collateral, the ceiling is around 70%, while standard long-term rentals reach 75% on cash-out.
- Credit score: typically 640 or higher for STRs. The strongest tiers want more.
- Experience: about 12 months of landlord or host experience is usually expected.
- Loan size: up to $3,000,000 on standard programs. Smaller balances route through select lenders.
- Reserves: commonly around 6 months of PITIA, meaning cash left in the bank after closing. Lender, leverage, loan size, and transaction type move that number. Larger loans typically step up.
- Terms: the 30-year fixed is the spine. Extended terms and interest-only periods are available through select lenders, and ARMs exist for investors who want them.
Michigan carries no state-specific LTV overlay in these programs. An U.P. buyer sees the same purchase tiers as an investor anywhere else. The strongest files clear two tests: enough equity and enough rental coverage.
If you’re weighing this against a traditional loan, STR DSCR versus a conventional loan lays out the trade-offs. If your income is documented through deposits, a comparison of STR DSCR and bank-statement financing is worth reading.
Key Terms Defined
DSCR (debt service coverage ratio): Gross rental income divided by the full monthly housing payment. It measures whether rent covers the payment, nothing more.
PITIA: Principal, interest, taxes, insurance, and any HOA dues. It is the payment figure in the DSCR formula.
STR (short-term rental): A rental booked for stays of weeks or less, usually through platforms like Airbnb or Vrbo.
LTV (loan-to-value): The loan balance as a percentage of the property’s value. Lower LTV means more equity from you.
AirDNA: A market-data provider whose revenue projections are often used to estimate STR income when a property lacks history.
Form 1007 / Form 1025: Appraisal forms for rent. Form 1007 covers single-family rent schedules. Form 1025 covers 2-4 unit operating income.
Reserves: Liquid cash left after closing, often counted in months of PITIA.
Seasoning: The waiting period between buying a property and refinancing it. About 6 months is the common expectation for cash-out.
When the General Rule Breaks
The rules above hold most of the time. A handful of cases bend them.
- No STR history. A recent purchase has no trailing income. The file then leans on a market-data projection, subject to the discount and the lower-of convention.
- Permit without a clear transfer path. Underwrite it as long-term rent until the city says otherwise in writing.
- Summer-heavy cabins. Annualized coverage can clear while winter months run negative. Reserves are what carry you through, so budget for them.
- Sub-1.00 coverage. This is available through select lenders in the network, with leverage and terms adjusted. Expect lower leverage and different terms than a file that clears 1.00.
- Ineligible property types. Log homes, manufactured homes, and barndominiums are not offered.
- Blended or multi-unit buildings. A 2-4 unit property is appraised on Form 1025, which gives each unit its own rent opinion. Confirm how a lender treats a mix of STR and long-term units.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
What the Decision Looks Like in Practice
Start with legality, not with the listing. Get written confirmation of permit status for the exact parcel. Then run both income numbers: the discounted STR projection and the long-term-rent fallback.
Next, see which ratio each number produces. If the lower one clears 1.00, your options widen. If it doesn’t, ask whether more down payment, a different property, or a sub-1.00 structure fits your plan.
Then check the non-ratio items: credit score, hosting experience, reserves, and property type. A strong ratio doesn’t rescue a weak file in those areas.
(Honestly, this is a toss-up for many buyers: a permitted Marquette house costs more but gives you cleaner income, while a cabin near Pictured Rocks costs less and carries more permit risk.) Neither is wrong. The right pick depends on your reserves and how much uncertainty you can carry through a slow season.
Frequently Asked Questions
Can I use DSCR financing on a cabin near Pictured Rocks?
Often yes, if the structure is an eligible property type and the local permit situation supports your income plan. Confirm which municipality governs the parcel before relying on STR income.
What happens if my property sits empty in winter?
Lenders review the file on annualized income, not month by month, so a quiet winter doesn’t automatically sink the file. It does stress your cash. Reserves, commonly around 6 months of PITIA, exist for exactly that gap. Plan for slow months even when the ratio clears.
Does a high AirDNA projection qualify the loan?
No. Programs discount projections, and the lower-of convention can cap your number at the long-term-rent estimate. Model both figures before you bid.
Can I buy in Mackinac Island and count nightly income?
Not until you’ve confirmed nightly stays are allowed at that address. Sources conflict, and comps are thin. If nightly rentals aren’t allowed, underwrite the property as a long-term or 30-day-plus rental.
Does Michigan have special leverage limits for DSCR loans?
No state-specific LTV overlay applies in these programs. Purchase leverage on STR collateral still tops out at 75% on the strongest files, and refinance and cash-out tops out around 70%. Credit, reserves, and property review still apply.
