A duplex, triplex, or fourplex is a multi-unit, income-producing property that still falls within the residential mortgage framework rather than the commercial financing framework generally used for apartment buildings with five or more units. LendSure Home Loans’ DSCR program finances 1–4 unit investment properties up to $3,000,000, qualifying on the property’s rental income rather than personal income.
LendSure Home Loans offers DSCR financing for 1–4 unit investment properties with no tax returns, no W-2s, and no personal debt-to-income calculation. If you have a property in mind, our team can run a DSCR scenario based on the purchase price, unit-by-unit rent, and expected financing before you make an offer.
What Makes 2–4 Units Different From a Single-Family Rental
A single-family rental produces one income stream. A 2–4 unit property produces multiple, which changes the risk profile and the qualification logic in meaningful ways.
| Duplex | Triplex | Fourplex | |
| Units | 2 | 3 | 4 |
| One vacancy = share of units vacant | 50% | 33.3% | 25% |
| Rental income streams | 2 | 3 | 4 |
| Tenant and lease complexity | Lower | Moderate | Higher |
| Within 1–4 unit residential category | Yes | Yes | Yes |
| DSCR financing eligible | Yes | Yes | Yes |
More units can diversify vacancy risk — one empty unit affects a fourplex less than a duplex. More units also mean more tenants, more leases, more maintenance, and more operating complexity. Both sides of that equation matter before you make an offer.
DSCR vs. a Conventional Investment Loan
This is the question most buyers are actually asking when they search for multifamily DSCR financing. The difference is not just documentation — it is the fundamental structure of how you qualify.
| DSCR Investment Loan | Conventional Investment Loan | |
| Main qualification emphasis | Property rental cash flow | Borrower’s overall qualifying profile plus property |
| Personal income docs | Not required | Generally required |
| Personal DTI | Not the primary qualifier | Matters significantly |
| Rental income | Central to qualification | Can be used, subject to guidelines |
| Credit | Still matters | Matters |
| 2–4 units eligible | Yes | Yes, subject to guidelines |
With a conventional investment loan, the lender considers your income, debts, credit, assets, and the property together — rental income can factor in, but it’s one piece of a broader personal-finance qualification.
With a DSCR loan, the central question is whether the property’s rental cash flow supports its debt obligation under the lender’s specific program. That is why an investor with strong assets but complex or limited income documentation investigates DSCR financing in the first place.
Three Calculations Buyers Need to Understand
Most DSCR articles treat qualification and profitability as the same thing. They are not. There are three separate calculations, and confusing them is one of the most common mistakes first-time multifamily investors make.
1. Lender DSCR (Qualification)
LendSure Home Loans calculates DSCR by dividing the property’s gross rental income by its monthly PITIA: principal, interest, taxes, insurance, and association fees. A ratio of 1.0 means rent exactly covers the full housing obligation. LendSure Home Loans commonly works with ratios at or above 1.0, and lower ratios can be considered on a case-by-case basis, down to 0.75 with exceptions to 0.25. This calculation determines whether the loan qualifies — it does not determine whether the investment is profitable.
2. Property Operating Cash Flow (Reality)
The IRS publication on rental income and expenses identifies common rental expenses including maintenance, insurance, taxes, management fees, repairs, utilities, and depreciation. A fourplex generating $8,000 per month in gross scheduled rent does not net $8,000 per month. The operating picture after vacancy allowance, management fees, repairs, and owner-paid expenses looks materially different. Passing the lender’s DSCR test does not mean the property cash flows the way you expect.
3. Investor Return (Your Actual Result)
Return is what you earn relative to the capital you put in. Two properties can pass the same DSCR threshold and produce very different investor returns depending on purchase price, renovation needs, financing terms, and ongoing operating costs. A property that qualifies at 1.15 DSCR on a well-priced acquisition with stable long-term tenants is a different investment from one qualifying at 1.15 DSCR on an inflated purchase price with month-to-month tenants.
What Rental Income Does the Lender Actually Use?
This is one of the most practical questions a buyer can ask before making an offer, and the answer depends on the property’s circumstances.
Consider a fourplex with mixed occupancy:
| Unit | Current Rent | Market Estimate |
| A | $1,450 | $1,800 |
| B | $1,500 | $1,800 |
| C | $1,750 | $1,850 |
| D | Vacant | $1,850 |
LendSure Home Loans uses the lesser of the existing lease or the appraiser’s market rent estimate for occupied units, and the appraiser’s Form 1007 market rent schedule for any vacant units. All units are assumed rented at market rate for qualification purposes. The income figure used for DSCR is not simply what the current owner collects — it reflects the property’s market rental potential as documented by an independent appraiser.
Can You Live in One Unit With a DSCR Loan?
This question comes up immediately when buyers see “multifamily.” The answer with LendSure Home Loans’s DSCR program is no. DSCR loans are investment-property loans for non-owner-occupied rentals. A buyer who plans to occupy one unit while renting the others needs owner-occupied financing, not an investor DSCR loan. Buyers in that scenario should discuss appropriate financing options based on their intended occupancy.
Short-term rental income from platforms like Airbnb and Vrbo is accepted under LendSure Home Loans’s DSCR program for qualification purposes when documented with a 12-month earnings history. That flexibility matters for investors targeting vacation rental markets or urban short-term rental strategies.
Don’t Underwrite at 100% Occupancy
The national rental vacancy rate was 7.3% in Q2 2026, according to the U.S. Census Bureau’s Housing Vacancy Survey, but that national figure tells you very little about a specific property in a specific market. Local vacancy rates vary widely: Innago’s analysis of Census data shows state-level vacancy ranging from 2.5% in Maine to 12%+ in South Carolina.
The practical implication for a multifamily buyer is straightforward. A fourplex underwritten at four occupied units generating $7,400 per month needs a realistic occupancy assumption, not a permanent full-house projection. Research the local rental market before making an offer — not after you own the building.
What Cash Do You Actually Need at Closing?
Down payment is one number. The total cash requirement to close is a larger one.
- Equity contribution: For 1–4 unit investment properties, LendSure Home Loans finances up to 85% LTV on a purchase, meaning the equity contribution is at least 15%
- Closing costs: Title, escrow, appraisal, and lender fees
- Reserves: LendSure Home Loans requires verified liquid or near-liquid assets beyond closing; retirement accounts are acceptable
- Vacancy buffer: Funds to cover the mortgage obligation during any lease-up period or tenant turnover
- Immediate repairs: Any work required before the units can be rented at target rents
An investor who budgets for the equity contribution but not the full cash stack is frequently surprised at the closing table. Building the complete picture before making an offer is what separates a smooth close from a scramble.

Frequently Asked Questions
What is a multifamily DSCR loan and how does it work?
A DSCR loan for a 2–4 unit property qualifies on the property’s rental income rather than the borrower’s personal income. LendSure Home Loans calculates DSCR by dividing gross rental income by the property’s monthly PITIA — principal, interest, taxes, insurance, and HOA fees. A ratio at or above 1.0 means the rent covers the full housing obligation. No tax returns, W-2s, or personal debt-to-income calculation are required.
Do I need landlord experience to qualify for a 2–4 unit DSCR loan?
No. LendSure Home Loans’s DSCR program does not require prior landlord or investment property experience. Qualification is based on the property’s rental performance, the borrower’s credit profile, and available liquidity — not a track record of property management.
What if one or more units are vacant at the time of purchase?
Vacant units are qualified at the appraiser’s market rent estimate using Form 1007, the rent schedule included in the appraisal. All units are assumed rented at market rate for qualification purposes. An existing lease at below-market rent may result in the lesser of the lease amount or market rent being used for that unit.
Is a duplex, triplex, or fourplex considered commercial real estate?
No. Properties with 1 to 4 units fall within the residential mortgage framework, not commercial real estate financing. LendSure Home Loans’s DSCR program finances 1–4 unit properties up to $3,000,000, with purchase LTVs up to 85%. A five-unit-or-more property crosses into commercial multifamily territory, which falls outside LendSure’s 1–4 unit DSCR parameters — 5–10 unit properties are financed under separate terms, up to 75% LTV.
Can I use short-term rental income (Airbnb, Vrbo) to qualify?
Yes. LendSure Home Loans accepts short-term rental income for DSCR qualification when documented with a 12-month earnings history from the platform. This matters for buyers targeting vacation markets or urban short-term rental strategies.
What DSCR ratio does LendSure require?
LendSure Home Loans commonly works with DSCR ratios at or above 1.0. Ratios as low as 0.75 are considered, with exceptions down to 0.25 on a case-by-case basis. Lower ratios result in lower leverage and different pricing — the ratio drives both approval and loan structure.
