DSCR Loan Case Study: Cash-Flowing Duplex in Atlanta

This walkthrough shows how a DSCR loan works in practice for a rental property acquisition. The numbers are drawn from a real deal profile in the Atlanta metro area, anonymized to protect borrower privacy.

Property: Side-by-side duplex in a suburban Atlanta neighborhood. Each unit is 2 bedrooms, 1 bath, approximately 900 square feet per side. Built in 1995, the property was in good condition with minor cosmetic updates needed (paint, appliances, landscaping).

Purchase price: $285,000 Appraised value: $290,000 Loan amount: $213,750 (75% LTV) Down payment: $71,250 (25%) Interest rate: 7.25% (30-year fixed) Monthly gross rent: $2,800 ($1,400 per unit) Monthly PITIA: $1,958 DSCR ratio: 1.36x Monthly cash flow after PITIA: $485 (after 5% vacancy factor)

The borrower was a self-employed business owner who had been investing in real estate on the side for three years. He already owned two single-family rentals and wanted to add a duplex to his portfolio. His challenge was that his tax returns showed minimal adjusted gross income because of business deductions, write-offs, and depreciation. On paper, his income looked too low to qualify for a conventional investment property mortgage.

A DSCR loan solved this problem because qualification is based entirely on the property's rental income relative to its debt obligations. The lender does not look at the borrower's personal income, W-2s, or tax returns. Instead, the underwriting focuses on one question: does the property generate enough rent to cover the monthly payment?

In this case, the duplex generated $2,800 in gross monthly rent. After a 5% vacancy factor ($140), the effective gross income was $2,660. The total monthly PITIA (principal, interest, taxes, insurance, and no HOA) was $1,958. That produces a DSCR of 1.36x, meaning the property generates 36% more income than needed to cover the payment. Most DSCR lenders require a minimum of 1.0x to 1.25x, so this deal cleared the threshold comfortably.

The loan was a 30-year fixed-rate DSCR product at 75% LTV. Here are the key terms.

Loan amount: $213,750 Interest rate: 7.25% fixed for 30 years Monthly P&I: $1,458 Monthly taxes: $270 Monthly insurance: $230 Monthly PITIA: $1,958 Prepayment penalty: 3-year stepdown (3%, 2%, 1%) Reserves required: 6 months PITIA ($11,748)

The borrower brought $71,250 for the down payment, approximately $6,200 in closing costs, and $11,748 in reserve verification, for a total capital commitment of roughly $89,200. The reserves were not deposited with the lender but had to be verified in a bank account at closing.

One important nuance: the borrower elected a 75% LTV option rather than the maximum 80% available because the lower LTV came with a 0.375% rate reduction. On a $213,750 loan over 30 years, that rate difference saves approximately $16,200 in total interest over the life of the loan. For buy-and-hold investors planning to keep the property long term, the extra 5% down payment can be well worth the rate improvement.

Here is the monthly cash flow breakdown for this duplex.

Gross monthly rent: $2,800 Less vacancy (5%): -$140 Effective gross income: $2,660 Less PITIA: -$1,958 Less maintenance reserve (5%): -$140 Less property management (0% -- self-managed): $0 Net monthly cash flow: $562

If the borrower hired a property manager at 8% of collected rent, the cash flow drops to $338/month. Both scenarios are positive, which is the key qualifier for DSCR lending.

On an annual basis, the property generates $6,744 in net cash flow (self-managed) on $89,200 of invested capital, producing a 7.6% cash-on-cash return. That does not include principal paydown (approximately $3,400 in year one) or potential appreciation. Including principal paydown, the total return on capital is closer to 11.4% in year one.

The borrower plans to hold this property for at least 5 years. If Atlanta rents continue growing at 3-4% annually and the property appreciates at a similar rate, the projected equity position at year 5 is approximately $115,000-$130,000, including principal paydown and appreciation.

The DSCR loan process was straightforward compared to a conventional mortgage. Here is what the borrower provided.

Required documents: - Loan application - Entity documents (LLC operating agreement and articles of organization) - Two months of bank statements (for reserve verification only) - Current lease agreements for both units - Property insurance quote - Appraisal (ordered by lender) - Rent survey or comparable rent analysis

Not required: - Tax returns - W-2s or pay stubs - Profit and loss statements - Personal income verification of any kind

The lender ordered a full appraisal with a rent survey to verify that the $1,400/unit rent was supported by the market. The appraiser confirmed comparable duplexes in the area were renting between $1,350 and $1,500 per unit, validating the income assumption.

From application to closing, the process took 21 days. The borrower submitted documents on day 1, the appraisal was completed by day 10, underwriting cleared by day 16, and the loan closed on day 21. For an investor accustomed to the 45-60 day conventional mortgage process, this was significantly faster.

Several lessons from this deal apply broadly to DSCR rental investors.

The DSCR ratio is the deal. Everything flows from whether the rent covers the payment. Before you make an offer, run the DSCR math. If the ratio is below 1.0x, you either need a larger down payment, a lower purchase price, or higher rent to make the deal work. Use a DSCR calculator to model different scenarios before committing.

Lower LTV can save real money. Putting 25% down instead of 20% saved this borrower 0.375% on rate. Over 30 years, that adds up to over $16,000 in interest savings and $57/month in lower payments. If you have the capital, compare pricing at different LTV tiers before choosing your down payment amount.

Reserves matter more than income. DSCR lenders do not verify your income, but they care deeply about your liquidity. Having 6 months of PITIA in reserves shows the lender you can weather vacancy or unexpected repairs without defaulting. If your reserves are thin, consider waiting to buy until you have a stronger cash position.

Entity ownership is standard. Most DSCR borrowers hold properties in an LLC for liability protection. Unlike conventional mortgages, DSCR loans are designed for entity borrowers. Set up your LLC before applying to avoid delays at closing.
