DSCR loans changed the investor financing market. Before DSCR existed as a mainstream product, real-estate investors had three bad options: conventional loans capped at 10 financed properties, hard-money loans at 11-13% rates, or commercial loans with 20-year amortizations and aggressive balloons. DSCR — Debt-Service Coverage Ratio — fixed that.

It’s a 30-year financing product priced near conventional rates that ignores the borrower’s personal income entirely and qualifies on the property’s projected rental income. That single mechanical change unlocked institutional-quality financing for individual investors at scale. This guide is the complete reference: how DSCR underwriting works mechanically, what the math actually looks like, what MBANC’s program parameters are, where DSCR wins vs. competing products, and the operational details that determine whether your file closes or stalls.

What is a DSCR loan

A DSCR loan is a Non-QM mortgage that qualifies a residential investment property based on its Debt-Service Coverage Ratio — a single number expressing whether the property’s rental income covers its mortgage payment. DSCR = Monthly Rent ÷ Monthly PITI DSCR of 1.00 = rent exactly covers the principal, interest, tax, and insurance payment DSCR of 1.25 = rent covers 125% of the payment (positive cash flow) DSCR of 0.85 = rent covers 85% of the payment (slight negative) Lenders set a minimum DSCR threshold for approval.

At MBANC, we underwrite down to 0.75 DSCR on qualifying properties — meaning we’ll lend on properties where the rent covers 75% of the payment, with the borrower expected to make up the gap from other resources. The borrower’s other resources are not verified. That last sentence is what makes DSCR loans unique. The lender does NOT pull the borrower’s tax returns, W-2s, or bank statements.

The borrower’s personal financial position is largely irrelevant. What matters is the property. The historical context Before 2020, DSCR loans existed mostly as commercial products with commercial pricing and 5-7 year balloon structures. The 2020-2022 institutional capital influx into Non-QM created the residential DSCR product: 30-year amortization, fixed-rate option, 75-80% LTV, residential-grade rates.

That shift democratized investment-property financing. An individual investor with a $50,000 down payment could now finance a $250,000 rental property with the same product structure that institutional buyers used. The “mom and pop” investor and the institutional fund effectively use the same loan today. The Fannie Mae 10-property cap was the other catalyst.

Fannie’s underwriting limits a borrower to 10 financed 1-4 unit properties combined. Real-estate investors who hit that cap had no path forward via conventional channels. DSCR has no equivalent cap — borrowers with 50, 100, or more properties routinely use DSCR loans for portfolio growth. How the DSCR calculation actually works The DSCR underwriter executes a specific calculation.

The inputs and weighting matter. Step 1: Determine the rental income (numerator) There are three accepted sources, in order of preference: 1. Existing lease — if the property is already rented, the lease rent is used (subject to a market-rent adjustment if it’s well below comparable rents — the underwriter won’t use an obviously below-market lease to game the DSCR) 2.

Market rent appraisal (Form 1007) — the appraiser provides an opinion of market rent based on comparable rentals in the area. This is the standard for vacant properties. 3. Borrower’s projected rent — only acceptable in some markets and only on a unanimous appraiser/lender agreement that the projection is reasonable. Most lenders won’t accept this alone.

For short-term-rental (STR) properties, the calculation differs: Long-term rent equivalent — what would the property rent for as a regular long-term rental? This is the conservative number, and the one most lenders default to. STR projection — using AirDNA, Mashvisor, or comparable STR analytics, the appraiser may provide a projected STR income.

MBANC accepts this for established STR markets with clear regulatory permission. Step 2: Determine the property payment (denominator) The PITI: principal, interest, taxes, insurance. Principal & interest — calculated from the loan amount, rate, and amortization. For interest-only loans, only the interest portion is used (which makes DSCR easier to hit, but only during the IO period).

Property taxes — from the appraisal or local tax records. The annual tax divided by 12. Insurance — from the homeowners insurance quote. Annual divided by 12. For condos and HOAs, the monthly HOA dues are also added. Step 3: Compute the ratio Divide. The result is the DSCR. Step 4: Apply the underwriting matrix The DSCR result lands the file in a specific pricing tier: DSCR Ratio MBANC Treatment ≥ 1.25 Best pricing tier — full LTV available (80% purchase, 75% cash-out refi) 1.10 – 1.24 Standard pricing — full LTV 1.00 – 1.09 Slight pricing adjustment — full LTV 0.85 – 0.99 Higher pricing or LTV reduction (often 75% instead of 80%) 0.75 – 0.84 Maximum LTV typically 70-75%, higher rate add-on Decline (or significant LTV reduction to make the math work) The investor adjusts the loan amount to land the DSCR in the tier they want.

Want best pricing

Drop the LTV until the PITI is low enough that the DSCR sits at 1.25+. MBANC DSCR program parameters Specifically, what MBANC underwrites: Property types Single-family residences (SFR) 2-4 unit residential properties Condos (warrantable and non-warrantable) Townhomes Planned Unit Developments (PUDs) Short-term rentals (where local regulations allow) Non-warrantable condos (one of our strengths — many lenders decline these) Loan parameters Loan size: $150,000 minimum, $3,000,000 maximum (some markets up to $5M case-by-case) LTV: Up to 80% purchase, 75% rate-and-term refinance, 75% cash-out refinance DSCR minimum: 0.75 (with adjustments) Credit minimum: 660 (best pricing at 740+) Reserves: 6 months PITI for purchase, 3 months for refinance Borrower types: Individuals, LLCs, partnerships, trusts (US-based) Cash-out: Allowed up to 75% LTV; no seasoning requirement on purchase-to-refi for properties owned 6+ months Amortization options 30-year fixed (most common) 30-year fixed with 10-year interest-only period 40-year fixed with 10-year IO 5/6 ARM (5-year fixed, then 6-month adjustments) 7/6 ARM 10/6 ARM Rates (relative) 0.50-1.50% above comparable conventional investment-property loans Improvement of ~0.25% if borrowing through an LLC vs. individual Pricing improves with credit score, lower LTV, higher DSCR Where DSCR clearly wins The product is built for specific scenarios.

These are the obvious DSCR cases: The 11th property Fannie Mae caps borrowers at 10 financed 1-4 unit properties combined. Hit the cap, and conventional is structurally unavailable for property #11 onward. DSCR has no cap. Portfolio investors routinely use DSCR for properties 11-100+. The self-employed investor with aggressive write-offs Conventional underwriting uses Schedule C / K-1 net income.

A self-employed investor writing off $200,000 against $260,000 in business gross might show $60,000 net — which mathematically can’t support an investment-property mortgage even with the projected rental income added back. DSCR ignores the personal income entirely. The property qualifies itself. The LLC structure investor Conventional loans require personal liability (and personal income documentation).

Investors who want the property to live in an LLC (for liability protection, partnership structure, or estate planning) often can’t get conventional financing in the entity’s name. DSCR loans can close directly in an LLC’s name with the individual(s) as personal guarantors. The property is the asset; the LLC is the borrower; the individual is the guarantor.

The short-term rental investor Many conventional lenders won’t lend on properties intended for short-term rental, even if the property qualifies physically. DSCR lenders specifically built to handle STRs evaluate the cash flow and lend accordingly. MBANC underwrites STRs with documented permissibility under local STR regulations.

The non-warrantable condo A “non-warrantable” condo is one that fails Fannie Mae’s complex eligibility tests (HOA litigation, commercial space ratio, owner-occupancy ratio, etc.). Conventional loans decline these. DSCR lenders evaluate the condo on the same merits as any property — the rental cash flow — and lend. The investor closing in 14 days Conventional investment-property closes take 30-45 days.

DSCR closes can run 14-21 days because there’s no borrower income documentation to underwrite. For competitive purchases (especially in tight investor markets), the speed alone justifies the rate premium. Where DSCR doesn’t win For balance, the cases where DSCR is the wrong product: Property under $150,000 Most DSCR lenders set a $150,000 minimum loan amount.

The fixed underwriting cost doesn’t make economic sense below that. Smaller properties usually finance via portfolio loans from local community banks. Borrower with strong W-2 income and ≤10 properties If your W-2 income easily supports the loan via conventional DTI math, and you’re below the 10-property cap, conventional is cheaper.

The DSCR rate premium isn’t worth paying. Properties with negative cash flow at any reasonable LTV If a property won’t hit 0.75 DSCR even at 70% LTV, the project itself probably doesn’t make sense as a long-term rental. Reconsider the buy. Owner-occupied scenarios DSCR is investment-only. Owner-occupied buyers should use bank statement, 1099, or conventional programs depending on their income profile.

Foreign nationals (use FN program instead) DSCR with a foreign national borrower is technically possible but the better product is MBANC’s dedicated Foreign National Loan program, which handles international asset documentation more efficiently. Real DSCR scenarios with the full math Scenario A: The straightforward purchase $385,000 SFR purchase in a Tier 2 market Existing tenant paying $2,950/month under a 12-month lease, 6 months remaining Borrower wants 25% down ($96,250), $288,750 loan, 30-year fixed at 7.5% Property taxes: $4,800/year ($400/month) Insurance: $1,200/year ($100/month) Monthly PITI: P&I: $2,019 Tax: $400 Insurance: $100 Total: $2,519/month DSCR: $2,950 ÷ $2,519 = 1.171 This DSCR lands in the 1.10-1.24 tier — standard pricing, full LTV available. Clean closure.

Scenario B: The marginal cash-out refi Borrower owns property, current loan balance $156,000, property value $295,000 Property rents for $2,300/month Wants to pull cash out — maximum $221,250 (75% LTV) New loan would have rate of 7.875% (cash-out adjustment) Property taxes: $3,200/year ($267/month) Insurance: $900/year ($75/month) Monthly PITI on the new $221,250 loan: P&I: $1,604 Tax: $267 Insurance: $75 Total: $1,946/month DSCR: $2,300 ÷ $1,946 = 1.182 DSCR clears 1.10. The cash-out delivers $65,250 to the borrower (the difference between the new loan balance and the old, minus closing costs). Clean closure.

Scenario C: The DSCR-below-1.00 purchase $625,000 SFR in a tight market Market rent appraisal at $3,750/month Borrower with 20% down, $500,000 loan at 7.75%, 30-year fixed Property taxes: $7,800/year ($650/month) Insurance: $2,400/year ($200/month) Monthly PITI: P&I: $3,581 Tax: $650 Insurance: $200 Total: $4,431/month DSCR: $3,750 ÷ $4,431 = 0.846 This DSCR lands in the 0.85-0.99 tier — slightly higher rate, possibly 75% LTV instead of 80%. If the borrower can put 25% down instead of 20%, the loan amount drops to $468,750, monthly P&I drops to $3,357, total PITI drops to $4,207, and DSCR rises to 0.891 — still below 1.00 but with a better LTV position for the lender. This is the typical “tight DSCR” scenario where investors adjust down payment to land the file where it needs to be.

Scenario D: The portfolio play Borrower owns 14 financed properties (all under DSCR loans, way past Fannie’s 10-property cap) Buying property #15: $475,000, 25% down, $356,250 loan at 7.5%, 30-year fixed Existing tenant paying $3,400/month Property taxes: $5,400/year ($450/month), insurance: $1,500/year ($125/month) Monthly PITI: P&I: $2,491 Tax + insurance: $575 Total: $3,066/month DSCR: $3,400 ÷ $3,066 = 1.109 DSCR clears 1.10. Standard pricing. No issue with the 14 existing properties — DSCR doesn’t care.

The 15th property qualifies on its own. This is the structural advantage that makes DSCR irreplaceable for portfolio investors. Operational gotchas 1. The HOA monthly fee Many investors forget to include HOA dues in the PITI calculation. The underwriter doesn’t. A $250/month HOA on a $3,000-rent property pulls 8% off your DSCR calculation.

Build it in from the start. 2. Insurance escrow Some lenders require escrowed taxes and insurance; others allow waiver. Escrowed payments may use a slightly higher reserve estimate than your actual policy. Confirm whether escrows are mandatory in your file. 3. Vacancy assumption The DSCR calculation uses *gross* monthly rent, not net-of-vacancy.

Conservative investors should run their own internal “DSCR-after-vacancy” calculation at 8-12% vacancy assumption to make sure the file works in reality, not just on paper. 4. The 6-month seasoning rule Most lenders require you to own the property for 6 months before a cash-out refinance. Buying and immediately cash-out refinancing isn’t possible (with exceptions for some delayed-financing programs that effectively reverse the order).

5. Prepayment penalty DSCR loans almost universally carry a prepayment penalty for the first 3-5 years. If you plan to flip the property or refinance within 3 years, factor in the prepay penalty cost. MBANC offers no-prepay options at slightly higher rates for investors who need flexibility. DSCR vs. competing products (quick reference) Product When to use DSCR loan Investment property, long-term hold, any borrower complexity, 11th+ property Conventional investment First 10 properties, clean W-2 borrower, lowest rate priority Hard money Fix-and-flip with under-12-month exit, property not currently rentable Commercial loan 5+ unit properties, mixed-use, $5M+ deals Portfolio loan Small local community bank relationship, sub-$150K properties HELOC on primary Equity tap from primary residence to fund investment down payment 1031 exchange Selling existing investment to buy new (defers capital gains; loan is separate) Frequently asked questions Can I use a DSCR loan for a primary residence?

No. DSCR loans are strictly investment-only. For primary-residence purchases where conventional doesn’t work, use bank statement, 1099, or asset utilization programs. Does a DSCR loan affect my personal credit? Yes — the loan reports on your personal credit report (because you’re the personal guarantor, even when borrowing in an LLC).

The monthly payment is also factored into your personal DTI by future lenders. What if I want to lend in my LLC’s name? MBANC supports LLC-borrower closings. The LLC is the borrower; the LLC’s members are personal guarantors. The LLC needs to be in good standing in its state of formation and have a clear operating agreement.

Can I refinance my DSCR loan

Yes — both rate-and-term and cash-out. Cash-out refinances are particularly common as a way to extract equity for the next property purchase (the “BRRRR” strategy). What if my property’s DSCR is below 0.75? MBANC’s hard floor is 0.75. Below that, you’ll need a larger down payment to bring the loan amount (and thus PITI) low enough to clear the threshold.

Can I get an interest-only DSCR loan

Yes. MBANC offers 10-year IO followed by 20-year amortization on 30-year terms, and 10-year IO followed by 30-year amortization on 40-year terms. The IO period reduces the PITI calculation (because there’s no principal payment), making DSCR easier to hit. Do DSCR loans require appraisals?

Yes — both a property value appraisal AND a Form 1007 market rent comparable appraisal. The 1007 produces the “market rent” that the lender uses in the DSCR calculation if there’s no existing lease. How long do DSCR loans take to close? Clean files close in 14-21 days. The longest pole is typically the appraisal (5-10 days).

Once that’s in, processing and funding can happen in 5-7 additional days. Can foreign nationals use DSCR? Technically yes, but the better product is MBANC’s Foreign National Loan program, which is specifically designed for non-US-person investors and handles international documentation more efficiently. Is there a minimum number of investment properties I need before getting a DSCR loan?

No. First-time investors can get DSCR loans. The product is structured around property qualification, not investor experience. Getting started If you’re considering a DSCR loan, the most efficient next step is a real underwriter review of your specific scenario. MBANC returns Clear Approvals within 24 hours, with no credit pull required for the initial assessment.
