DSCR Loan Calculator — FAQ

DSCR stands for Debt Service Coverage Ratio. It measures whether a property's income covers its debt payments. The formula is: DSCR = Net Operating Income (NOI) ÷ Annual Debt Service. A DSCR of 1.25 means the property generates 25% more income than needed to cover the mortgage. A DSCR below 1.0 means the property doesn't generate enough income to cover its own debt.
Most DSCR lenders require a minimum ratio of 1.0–1.25. Conservative or portfolio lenders often require 1.25+. Some lenders offer "no ratio" DSCR loans that ignore the income and simply require a large down payment (30–35%). The higher your DSCR, the better your rate and terms will be. A ratio of 1.35+ typically qualifies for the best available DSCR rates.
A conventional mortgage qualifies borrowers based on personal income (W-2, tax returns, and debt-to-income ratio). A DSCR loan qualifies based on the property's income relative to its debt service — no W-2 or personal income verification required. This makes DSCR loans ideal for self-employed investors, those with multiple properties, or anyone whose personal income doesn't reflect their investment capacity.
Yes — DSCR lenders for STR properties typically accept projected or documented Airbnb income. Lenders may use a CPA letter, 12 months of Airbnb payout history, a market analysis from AirDNA, or a lease agreement equivalent. Some lenders use a "market rent" methodology rather than STR income projections, so it's important to find a DSCR lender specifically familiar with short-term rental underwriting.
Most DSCR lenders require a minimum 660–680 credit score, with the best rates available at 720+. Some lenders may offer DSCR programs at 640+ with larger down payments. Unlike conventional loans, your debt-to-income ratio is not the primary qualifying factor — the property's DSCR is. However, credit score still significantly impacts your interest rate offer.
DSCR loans for investment properties typically require 20–25% down payment. Some lenders offer 15% down for very strong DSCR ratios (1.35+). Cash-out refinance DSCR loans may allow up to 75% LTV. The down payment requirement is higher than owner-occupied mortgages because investment properties carry higher default risk — lenders price this in through both down payment requirements and interest rates.
Yes, typically by 0.5–1.5% above a comparable conventional 30-year fixed rate. As of 2026, DSCR rates for STR properties typically range from 7.0–8.5% depending on credit score, LTV, property type, and lender. This rate premium reflects the higher risk profile of investment properties versus owner-occupied homes. You can reduce the rate premium with a higher credit score, larger down payment, or by paying origination points.
DSCR loans are available for condos, cabins, vacation homes, and most single-family investment properties. However, condos in unapproved or non-warrantable condo projects may face restrictions. Short-term rental restrictions in HOA documents can also complicate DSCR financing — always verify the HOA allows STR before applying. Rural properties and cabins are generally eligible, though some lenders have minimum property value requirements.
Lenders may use: (1) 12 months of Airbnb/VRBO payout statements, (2) CPA-prepared profit and loss statement, (3) Airbnb's own income verification letter, (4) a third-party market analysis from AirDNA or Mashvisor showing comparable properties, or (5) a lease or management agreement for future bookings. Requirements vary by lender. First-time STR investors without operating history may need to use projected income supported by market data.
A DSCR below 1.0 means the property's income doesn't cover its debt service. Lenders will typically not approve a purchase with sub-1.0 DSCR. If an existing property's DSCR drops below 1.0 after closing (due to lower occupancy or rising expenses), it doesn't trigger a loan default — but it does mean you're funding the gap from personal reserves. Strategies to restore positive DSCR include: increasing ADR, improving occupancy, refinancing to lower debt service, or reducing operating expenses.

DSCR Loans: The STR Investor's Financing Advantage

How DSCR Loans Differ From Conventional Investment Loans

Conventional investment property loans qualify borrowers based on personal income, debt-to-income ratio, employment history, and credit score. For investors with multiple rental properties or non-traditional income sources such as self-employment or business income, these requirements create a hard ceiling on how many properties they can finance through conventional lending. DSCR loans break through this ceiling by qualifying based on the property's income, not the borrower's.

DSCR stands for Debt Service Coverage Ratio: the ratio of the property's net operating income to its annual mortgage payments. A DSCR of 1.25 means the property generates 25% more income than it costs to service the debt. Most DSCR lenders require a minimum DSCR of 1.0 to 1.25 depending on the loan type, property type, and lender. The critical difference from conventional loans is that your personal W-2 income, employment status, and debt-to-income ratio are not qualifying factors.

For short-term rental investors, DSCR loans are particularly valuable because STR income is inherently variable and not easily documented through traditional means. Many STR investors are self-employed or derive income from multiple properties, making conventional qualification difficult or impossible at scale. DSCR lenders typically use a blended income calculation based on actual rental history or market rent estimates, with most requiring at least 12 to 24 months of rental history or a third-party market rent analysis from an approved appraiser.

DSCR = Net Operating Income / Annual Debt Service

What DSCR Ratio Do You Need to Qualify?

Most DSCR lenders require a minimum ratio of 1.0, meaning the property's income must cover its debt payments. However, a 1.0 DSCR is typically the floor for qualification, not the target. At exactly 1.0, any reduction in income or increase in expenses pushes the property into negative coverage, creating default risk. Lenders price this risk accordingly: loans with DSCR ratios of 1.0 to 1.10 typically carry higher interest rates (often 0.25 to 0.50% higher) and may require larger down payments than loans with ratios of 1.25 or higher.

For short-term rental properties, the income calculation method matters enormously. Some lenders use the actual STR income from your tax returns or bank statements. Others use only 75% of projected STR income as a conservative stress test. A small number use long-term rental comparable market rents (often lower than actual STR income), which can severely penalize STR investors relative to their actual property performance. Before applying for a DSCR loan, ask the lender exactly how they calculate income for short-term rental properties.

A property at the margin of qualification (DSCR of 1.0 to 1.15) creates ongoing risk beyond just the initial qualification. If market conditions deteriorate and occupancy drops, the property can fall below the DSCR floor, creating a technical default or triggering covenant requirements. Strong STR investors target a DSCR of 1.25 to 1.5 as their investment threshold, which provides sufficient cushion against revenue volatility while still qualifying for competitive loan terms.

How to Improve Your DSCR Before Applying

Increasing your DSCR before applying for financing can reduce your interest rate, increase your borrowing capacity, and expand your pool of eligible lenders. There are two ways to improve DSCR: increase income or reduce debt service. Increasing income means optimizing ADR through dynamic pricing tools, improving occupancy through listing quality and review management, or adding amenities that command a booking premium. Each percentage point improvement in occupancy directly improves your DSCR.

Reducing debt service requires a lower interest rate, a lower loan amount (larger down payment), or a longer amortization period. A larger down payment is the most direct lever: moving from 25% to 30% down on a $500,000 property reduces the loan amount by $25,000, reducing annual debt service by roughly $2,000 at current rates. That improvement in debt service directly improves DSCR. Comparing quotes from multiple DSCR lenders is particularly valuable because DSCR pricing varies more than conventional loan pricing.

Timing your application to coincide with peak rental history is a practical strategy for properties with strong seasonal performance. If your property generates 70% of annual revenue in summer months, applying in September when the previous 12 months of bank statements show the strongest income period gives lenders the most favorable income picture. Keep clean, organized financial records from the first day of operation because documentation quality directly affects what lenders will count toward qualifying income.
