The quick read: A DSCR loan on a Baltimore rowhouse rental is sized on the building's rent divided by the full monthly payment, not on the investor's personal income. NerdWallet's DSCR guide (updated July 17, 2026) says that payment includes principal, interest, taxes, insurance and HOA fees, and that lenders typically want a ratio of around 1.25 or higher. In Baltimore the tax line decides the answer. The city's Bureau of the Budget and Management Research lists the Fiscal 2027 real property rate at $2.248 per $100 of assessed value, and the state's fiscal 2026 table shows no Maryland jurisdiction with a higher total local rate. A DSCR built on a Baltimore County or Howard County tax assumption will overstate coverage on a Canton or Federal Hill rowhouse. Build the tax line from the city rate, then confirm the rental license before you count the rent.
How do you qualify for a DSCR loan on a Baltimore rowhouse rental?
You qualify for a DSCR loan on a Baltimore rowhouse rental by showing that the documented rent covers the full monthly payment, taxes and insurance included, by the lender's required ratio, which NerdWallet says is typically around 1.25 or higher, on a rent-ready property you will not live in, with good credit and at least 20% down.
NerdWallet writes the debt service coverage ratio as monthly rental income divided by the monthly loan payment, and its own example is $3,000 of rent against a $2,500 payment, a ratio of 1.2. A DSCR calculator runs the same math on your numbers. NerdWallet describes the typical terms this way; every lender sets its own sheet:
Typical minimum DSCR (NerdWallet, updated Jul 17, 2026): around 1.25 or higher Credit score (NerdWallet, updated Jul 17, 2026): at least 620 Down payment (NerdWallet, updated Jul 17, 2026): at least 20% Minimum loan amount (NerdWallet, updated Jul 17, 2026): around $100,000 Reserves (NerdWallet, updated Jul 17, 2026): three to six months of mortgage payments Property condition (NerdWallet, updated Jul 17, 2026): rent-ready, no fixer-uppers
Two of those lines bite on rowhouse stock. NerdWallet says a DSCR loan can't be used to buy a primary residence, so an investor who will live on the first floor of a Highlandtown two-unit conversion should price an owner-occupied mortgage instead. And the property must be rent-ready. In Baltimore, rent-ready means more than paint: the unit has to be legally licensed as a rental, which the sections below walk through.
Why do Baltimore property taxes dominate the DSCR?
Baltimore property taxes dominate the DSCR because the city's real property rate is $2.248 per $100 of assessed value for Fiscal 2027, about twice Baltimore County's $1.10 in the state's fiscal 2026 table, so on the same rowhouse value the tax line can be the largest expense after principal and interest.
The Department of Legislative Services publishes every county's local rate. Baltimore City's rate has been $2.248 in every year from fiscal 2022 through fiscal 2026, and in the department's fiscal 2026 table of every county and municipality, no jurisdiction shows a higher total local rate (our reading of the table). The state adds its own rate on top: the Board of Public Works set the fiscal 2026 state rate on most real property at 11.2 cents per $100 of full assessed value.
| Line (per $100 of assessed value) | Baltimore City | Baltimore County | Howard County | Anne Arundel County |
|---|---|---|---|---|
| Line (per $100 of assessed value) Local rate, fiscal 2026 (DLS) | Baltimore City $2.248 | Baltimore County $1.100 | Howard County $1.250 | Anne Arundel County $0.977 |
| Line (per $100 of assessed value) State rate, fiscal 2026 (Board of Public Works) | Baltimore City $0.112 | Baltimore County $0.112 | Howard County $0.112 | Anne Arundel County $0.112 |
| Line (per $100 of assessed value) Local plus state (our arithmetic) | Baltimore City $2.360 | Baltimore County $1.212 | Howard County $1.362 | Anne Arundel County $1.089 |
| Line (per $100 of assessed value) Annual tax per $100,000 assessed (our arithmetic) | Baltimore City $2,360 | Baltimore County $1,212 | Howard County $1,362 | Anne Arundel County $1,089 |
The city's own tax page confirms the $2.248 rate carries into Fiscal 2027. Some neighborhoods add a special benefits district surcharge on top, so pull the parcel's actual bill rather than assuming the base rate is the whole charge.
The timing of the bill matters too. The Maryland Department of Assessments and Taxation says it reassesses each group of properties once every three years, phases any increase in evenly over the next three years, and applies decreases at once. Its 2026 reassessment raised Group 2 values 12.7% statewide. So a rowhouse bought today may carry an assessment from an earlier cycle that steps up each year after the next reassessment. SDAT also says the Homestead Tax Credit, which caps annual assessment increases at 10% under state law, applies to a homeowner's principal residence. If the seller lived in the house, ask whether the current bill reflects a credit that will not carry over to a rental.
What does the DSCR math look like on an illustrative Canton two-unit rowhouse?
On an illustrative $400,000 Canton rowhouse converted to two units and renting for $3,400 a month, a $300,000 loan at the assumed rate in the table below produces a DSCR of about 1.13 with the city's $2.36 combined rate, while the same building on a Baltimore County tax assumption shows about 1.30, a gap worth roughly $56,000 of loan.
Every input below is an illustrative assumption, not a quote, a market rate, an appraisal or a rent survey. Both columns assume an assessment equal to the price. The tax lines apply the fiscal 2026 local and state rates from the table above.
| Illustrative line (our arithmetic) | City tax line (correct) | County tax line (wrong for a city parcel) |
|---|---|---|
| Illustrative line (our arithmetic) Value and assessment (assumption) | City tax line (correct) $400,000 | County tax line (wrong for a city parcel) $400,000 |
| Illustrative line (our arithmetic) Gross rent, two units (assumption) | City tax line (correct) $3,400.00 | County tax line (wrong for a city parcel) $3,400.00 |
| Illustrative line (our arithmetic) Loan at 75% of value | City tax line (correct) $300,000 | County tax line (wrong for a city parcel) $300,000 |
| Illustrative line (our arithmetic) Principal and interest, 7.25%, 30-year amortization | City tax line (correct) $2,046.53 | County tax line (wrong for a city parcel) $2,046.53 |
| Illustrative line (our arithmetic) Property tax, local plus state rate | City tax line (correct) $786.67 | County tax line (wrong for a city parcel) $404.00 |
| Illustrative line (our arithmetic) Insurance (assumption) | City tax line (correct) $175.00 | County tax line (wrong for a city parcel) $175.00 |
| Illustrative line (our arithmetic) Total payment | City tax line (correct) $3,008.20 | County tax line (wrong for a city parcel) $2,625.53 |
| Illustrative line (our arithmetic) DSCR | City tax line (correct) 1.13 | County tax line (wrong for a city parcel) 1.30 |
| Illustrative line (our arithmetic) Loan that reaches 1.25 | City tax line (correct) About $258,000 | County tax line (wrong for a city parcel) About $314,000 |
The left column is the one the lender will build, because it reads the city tax bill. At the city rate, the loan that reaches 1.25 is about $258,000, roughly 64% of value, so the buyer needs about $42,000 more cash at closing than a 75% plan assumed (our arithmetic). A Federal Hill or Pigtown purchase faces the same math: the rate is citywide, and only the price-to-rent relationship differs from block to block.
The fixes are the usual ones: a lower price, a larger down payment, more rent from a third unit where zoning and code allow it, or an assessment appeal if the city's value runs ahead of the building's.
What does Baltimore require before a rowhouse can be rented?
Baltimore requires every non-owner-occupied property to be registered each year and every rental to hold a license, and the license issues only after a passing third-party inspection, current lead certification for each unit, paid fees and no open code violations, so a lender's rent-ready test depends on that paperwork.
The city's Department of Housing and Community Development lists the steps on its registration and licensing page:
Registration (Baltimore DHCD): due by January 1 each year, and within 10 days of any transfer of the property License inspection (Baltimore DHCD): a passing report from a State licensed home inspector registered with the city, or a passing Section 8 inspection, submitted within 90 days of the inspection Lead (Baltimore DHCD): current lead certification information for each unit Violations (Baltimore DHCD): no open code violations License term (Baltimore City Code, Art. 13, sec. 5-9): new and renewal licenses expire 2 years from issuance Transfer (Baltimore City Code, Art. 13, sec. 5-12): a rental license cannot be transferred; a new owner applies within 60 days of taking title
The lead layer comes from the state too. The Maryland Department of the Environment says owners of rental homes built before 1978 must register with the state, renew annually by December 31 at $30 per unit, and provide a valid lead inspection certificate at each tenant turnover unless the property is certified lead-free. A change in ownership requires a new registration. On an older rowhouse, assume the rule applies until the records prove otherwise.
For a DSCR buyer, the practical point is section 5-12. The seller's license does not convey, so the purchase closes with rent that the new owner must re-license. Ask the seller for the current license, the last inspection report and every unit's lead certificate, and schedule your own inspection so the new license is in process at closing.
Which lenders finance Baltimore rowhouse rentals on DSCR?
DSCR and non-QM investor lenders are the core option for a non-owner-occupied Baltimore rowhouse or small conversion, portfolio banks and credit unions may underwrite the borrower alongside the building, and buildings of five or more units move into commercial multifamily programs that read the full operating statement.
DSCR and non-QM investor lenders. These lenders qualify the deal on the property's coverage. Compare the ratio, the leverage, the minimum loan amount, the reserve requirement and the prepayment schedule in writing.
Portfolio banks and credit unions. A lender that keeps the loan sets its own coverage inside the 85% supervisory ceiling for improved property in the interagency real estate lending guidelines (12 CFR Part 34, Subpart D, Appendix A). Those guidelines treat 1- to 4-family residential property that is not owner-occupied and residential property with five or more units as separate types of improved property.
Five units and up. A rowhouse block converted into five or more units is a commercial multifamily loan. Expect questions about operating expenses, vacancy and reserves.
Ask every lender three Baltimore questions: does it underwrite taxes from the current bill or a reassessed estimate; does it need the rental license in hand at closing; and how does it treat a unit that is vacant pending a lead certificate.
How do you get lenders competing for a Baltimore rowhouse DSCR loan?
You get lenders competing for a Baltimore rowhouse DSCR loan by sending each one the same complete package, with the leases, the city tax bill, the rental license and lead certificates, so every quote uses the city tax line. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors.
That is the brokerage case. YieldStack's software matches the deal against a catalog of 20,000+ loan programs, a count of programs rather than of lenders, so a two-unit Canton conversion reaches the programs sized for it. Human brokers then structure the request, negotiate for the borrower and carry the deal toward closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
What to send:
- Property address, SDAT account number and the current Baltimore City tax bill
- Current leases or a rent roll for every unit, with vacancy history
- The rental license, the last inspection report and each unit's lead certificate
- An insurance quote or the current declarations page
- Purchase contract or payoff statement, plus any repair scope
- Target loan amount, expected hold and the prepayment penalty you can accept
The Baltimore market hub collects our local material and the Maryland market hub covers the rest of the state. When the package is ready, send the deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The bottom line
A DSCR loan on a Baltimore rowhouse is one division: documented rent over the full payment. Build the tax line from the city's $2.248 rate plus the state rate, never a suburban one, plan for reassessment steps, and treat the rental license and every unit's lead certificate as part of rent-ready, because the seller's license does not transfer to you.
