The Quick Read: The two market types differ in how much legal risk sits on the income, not in how a DSCR loan is calculated. In a regulated market, you have to prove the permit before nightly revenue counts. In an open market, you mainly document the income and watch for rule changes after you buy.
- The DSCR formula is identical in both: qualifying income divided by PITIA, which is principal, interest, taxes, insurance, and any association dues.
- A regulated market tests whether the income is legal for you, as an investor and possibly as an entity, to earn.
- An open market tests whether the income is documented and durable, since rules can tighten later.
- On short-term rental collateral, select lenders in Lendmire’s wholesale network typically offer up to 75% LTV on a purchase and up to 70% on a refinance or cash-out, with a 640 minimum score and about 12 months of hosting history, subject to lender guidelines.
- Clearing a 1.00 coverage ratio is not the same as positive cash flow, in either market type.
Here is the honest answer on who each option suits. A regulated market fits an investor who can meet the local conditions, wants a permit that limits competition, and can live with a smaller revenue ceiling. An open market fits an investor who wants flexibility, wants to scale across several properties, and can absorb the risk that the rules change. Neither is safer by default. The regulated market puts the risk up front, where you can check it. The open market defers part of that risk to later, where you cannot.

Side-by-Side
The table below compares the two market types on the points a DSCR investor actually runs into. Program mechanics reflect select lenders in Lendmire’s wholesale network, which places files in both kinds of markets.
| Factor | Regulated Market | Open Market |
|---|---|---|
| Review basis | Property income that is legal at the address | Property income, documented |
| Documentation | Permit or registration plus income support | Income support plus a local rule check |
| Property types | Often narrowed by zoning or residency rules | Broader, but HOA and condo rules still apply |
| Entity vesting | Permit holder may need to be an individual | LLC vesting is common, per program terms |
| Timeline (qualitative) | Permit windows or caps can gate the purchase | Fewer permit gates before you offer |
| Reserve expectations | Vary by lender, leverage, and loan size | Same; commonly around 6 months of PITIA |
| Main risk | Permit denied, capped, or revoked | Rules tighten after you own the property |
| Fallback income | Long-term rent if STR income is not usable | Long-term rent if rules change later |
Notice what does not change from column to column: the leverage tiers, the credit minimum, and the coverage floor. Regulation changes which income the lender can use. It does not change the program.
What “Regulated” and “Open” Actually Mean
A regulated market is one where local rules limit who can host short stays, how many nights they can host, or whether a permit is required at all. An open market is one where those limits are light or absent. Most places fall between the two. 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 rule that matters most to investors is the primary-residence requirement. AirROI’s glossary explains that it limits permits to the owner’s actual home. In covered cities, that blocks non-owner-occupied investment properties from getting a short-term rental permit. The same page describes how cities check residency, using documents such as government ID, voter registration, and utility bills. It gives 270 or more days of residence as a typical standard, with some cities using 183.
Other common local conditions include caps on rental nights, limits on how many permits a host can hold, and permit lotteries. BiggerPockets’ short-term rental guide lists several of these, including rules that allow only part of a home, such as a basement or an accessory unit. It is older material, so treat it as general background.
Two points keep this from being a simple binary. First, a state allowing short-term rentals does not mean there are no rules, since registration and operating requirements can still apply. Second, condo and HOA bylaws can end short-term renting before the city ever gets involved.
Some places are as restricted as it gets. New York City is the textbook case, where the city’s Office of Special Enforcement hosting page is the official starting point for registration. For an absentee investor buying an entire unit, that kind of market generally cannot supply a legal short-term income basis.
When a Regulated Market Is the Better Fit
A regulated market is the better fit when you can satisfy the local conditions and you value a protected income stream over maximum upside. It rewards the buyer who does the homework first.
You want less competition. Permit caps and residency rules keep the supply of legal short-term rentals limited. A permit you hold can become a real asset, because a neighbor cannot simply list a competing unit tomorrow.
You will actually live there part of the time. If the local rule requires the host to occupy the home, a buyer who plans to do so is the intended user of that permit. That path usually runs through a different financing product than an investment loan, so confirm which one applies before you write an offer.
You prefer verifiable income. In a regulated market, the lender can ask for the permit or registration and see exactly what is allowed. That makes the income basis cleaner. A permitted property with a history of bookings gives the file two supports: legal status and trailing revenue.
You can wait on the permit. Caps, lotteries, and application windows can conflict with a purchase schedule. A buyer who can structure the offer around that gap, or who is buying a property that already holds a transferable permit, has an edge over one who cannot.
The tradeoffs are real. Entry barriers are higher, the revenue ceiling can be lower because of night caps, and paperwork is ongoing. There is also an entity wrinkle. Some local permits can be held only by an individual host. LLC vesting is common on investor loans, subject to program terms, so confirm who is allowed to hold the permit before you choose how to take title.
When an Open Market Is the Better Fit
An open market is the better fit when you want flexibility and room to grow, and you are comfortable carrying the risk that the rules shift. It rewards the buyer who plans for change.
You want to scale. With fewer permit gates, you can add properties without winning a lottery or finding another primary residence. The entry barrier is lower, so the question becomes whether each deal covers its payment.
You want to hold in an LLC. Where no residency-based permit applies, vesting in an entity is far simpler. Per lender program requirements, you will typically provide entity documents, and a personal guarantee is common.
You are building a record of hosting income. Since the program for short-term rentals expects about 12 months of hosting history, an open market lets a new operator build that record without a permit standing in the way.
Your thesis does not depend on scarcity. In an open market, anyone can add supply. If your numbers only work because competition is thin, that is a regulated-market thesis. If they work with more competition, an open market suits you.
The honest downside here gets skipped too often. Open does not mean safe. A market with few rules today can adopt rules later, and a new ordinance can cut the income you underwrote. Open markets can also fill with new listings, which pressures nightly rates and occupancy. For that reason, the stronger play is to underwrite an open-market deal so it still holds up if the income falls back to the long-term rent basis.
How a DSCR Loan Reads Either Market
The lender does not care whether a market is labeled regulated or open. It cares whether the income is legal, documented, and enough to cover the payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide walks through the basic mechanics.
The income basis. For a short-term rental, files commonly rely on trailing hosting history, a third-party projection when there is no history, or long-term market rent as a fallback. Which of these a lender accepts depends on the program and the property.
The appraisal piece. Form 1007 is the appraiser’s rent schedule for single-family homes, and Form 1025 covers two-to-four-unit properties. McKissock explains that the 1007 documents monthly rent rather than nightly revenue, and that how short-term income is used is ultimately the lender’s decision. Class Valuation warns that a 1007 used on a short-term rental can produce an artificially low coverage ratio. Fannie Mae’s appraiser update addresses the same questions for agency loans. DSCR loans do not follow agency rules, so treat that as contrast only.
This matters differently in each market. In a strong open market, a long-term-rent fallback understates what the property earns. In a weak or restricted market, that same fallback can be the number that rescues the file.
What the network offers on short-term rental collateral. Across the network, select lenders typically allow purchases up to 75% LTV. Refinances and cash-outs on short-term rental collateral generally top out around 70%. Most programs want a 640 minimum score and about 12 months of hosting history. The coverage floor is 1.00 on a purchase and 1.00 on a refinance. Standard programs reach up to $3,000,000 in loan size. Reserves vary by lender, leverage, and loan size, and about 6 months of PITIA is common.
A 1.00 floor is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Either way, approval depends on lender guidelines, credit review, and the property.
Manufactured homes, log homes, and barndominiums are not offered in these programs, in either market type.
A caution on the number. DSCR compares income to PITIA only. Cleaning, platform fees, utilities, repairs, vacancy, and management sit outside it. Short-term rentals usually carry heavier operating costs than long-term rentals, so a passing ratio is not a promise of positive cash flow.
In files like these, the stronger deals run the coverage ratio two ways before the offer goes in, once on projected short-term revenue and once on supported long-term rent. If both clear, the file has room. If only the short-term version clears, the buyer knows exactly how much the permit or the market is carrying.
A Worked Comparison
Run the numbers on one hypothetical property, modeled two ways. The ratios below are assumptions for illustration, not market data.
Picture a single-family home in a regulated market. An issued permit supports the short-term income, and projected short-term revenue produces coverage near 1.30x. Long-term rent on the same house lands below 1.00x.
Now picture the same house in an open market, where no ordinance limits how many nights it can be rented. Projected short-term revenue again produces coverage near 1.30x, while long-term rent again lands below 1.00x.
Both versions look workable on the short-term basis, and the ratios match. The difference is what holds that projection up. In the regulated case, a permit supports it. In the open case, only current market conditions do. If the permit is revoked in the first case, or an ordinance passes in the second, each file falls back to the long-term rent basis. At that point, coverage below 1.00 becomes a conversation about select lenders in the network, with leverage and terms adjusted, and eligibility stays subject to lender guidelines and property review.
A high coverage ratio is not the same as a durable one. A file that depends only on current market conditions can look stronger on paper while carrying thinner protection than a file supported by a permit.
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.
Pre-Offer Checklist
Verify in this order, because each step can end the deal before you spend more money on the next one.
1. Check zoning at the parcel. Confirm short-term use is allowed for that specific address, not just the city.
2. Confirm permit status. Find out whether a permit or registration is required, whether caps or a lottery apply, and whether an existing permit transfers to a new owner.
3. Read the HOA or condo documents. Association rules can bar short stays even where the city allows them.
4. Confirm who can hold the permit. Check whether an individual or an entity is permitted, and plan your vesting around the answer.
5. Ask the lender about eligibility. A broker can sort which programs fit the property, the income documentation, and your hosting history.
6. Run both income cases. Test projected short-term revenue and long-term rent, and know which one you are relying on.
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.
When the Rules Change After You Close
Rules can move in either direction. A market that opened up can close, and a restricted market can ease. This is why the long-term-rent fallback matters in both columns.
In a regulated market, watch for permit renewal terms and enforcement changes. In an open market, watch for proposed ordinances before they pass, since a new rule can cut usable income overnight. At refinance time, a lender will look at what income is legal and supported then, not what it was at purchase. A loss of permit or a new ordinance can push the usable income back to the long-term basis. That is a practical inference rather than a published rule, but it is how the math tends to work.
The Verdict
Choose the regulated market if you can meet the local conditions and want legal clarity and protected supply, and accept a lower revenue ceiling and more paperwork. Choose the open market if you want flexibility and scale and can absorb rule-change risk. In either case, the file should still make sense on the long-term-rent basis, because that is the number you fall back to if the short-term income stops being usable.
The two tests a strong file clears are the same in both markets: enough equity for the leverage tier, and enough rental coverage for the payment. A larger down payment can lift the ratio, but it does not erase leverage caps, credit floors, reserve rules, or property eligibility.

Frequently Asked Questions
Does regulated mean restricted?
Not necessarily. Regulated means rules exist, such as permits, night limits, or residency conditions. Restricted usually means short-term use is banned or blocked for investors. Many regulated markets remain workable for a buyer who meets the conditions.
Can I get a DSCR loan in a regulated market?
Often yes, when the short-term income is legal at the address and supported by documents. Eligibility depends on lender guidelines, the permit situation, and the property. On short-term rental collateral, purchases typically reach up to 75% LTV, with a 640 minimum score and about 12 months of hosting history.
What if an ordinance passes after I close?
The loan stays in place, but the income the property can legally earn may fall. That is why the long-term-rent fallback matters. If coverage drops below 1.00 at refinance, select lenders in the network have a path for it, with leverage and terms adjusted.
Does a permit transfer when I buy?
It depends on the local rules. Some permits stay with the owner, some stay with the property, and some must be reapplied for. Confirm this before you make an offer, since a purchase can close on a home that cannot get a permit.
Are open markets riskier?
They carry a different risk. You skip the permit hurdle, but you take on the chance that rules change and that new supply pressures income. An open market can be the stronger choice, provided the deal still covers its payment on the long-term basis.
Investors focused on short-term rentals can review DSCR loans for Airbnb and short-term rentals.
