Thinking about buying a duplex, triplex, or fourplex in North Hills? Small multifamily can help you offset your mortgage, build equity faster, and create steady cash flow if you buy and manage it well. The key is understanding how 2 to 4 unit properties work in Harford County and how to underwrite them with local data. This guide covers financing, zoning, rent comps, due diligence, and operations tailored to North Hills. Let’s dive in.
Why small multifamily in North Hills
Small multifamily attracts two types of buyers: owner-occupants who live in one unit and rent the others, and investors who want stable, local cash flow. Because these properties appeal to both groups, they often have a wider buyer pool than single-family rentals, which can help when you decide to sell.
North Hills benefits from proximity to major job centers across Harford County and the Baltimore metro area. Commuter access, shopping, parks, medical services, and neutral school considerations all help support rental demand. To size the opportunity, review county demographics like renter share, household income, and vacancy using the U.S. Census Bureau’s American Community Survey. Then localize your rent assumptions with on-market listings through MLS and feedback from area property managers. County-level rent benchmarks from the HUD Fair Market Rents for Harford County can serve as a starting point.
To price-check a target property, look at recent 2 to 4 unit sales in Bright MLS and track per-unit pricing or Gross Rent Multiplier. Combine this with a pro forma to see how the numbers work at today’s rents and realistic expenses.
Financing options for 2 to 4 units
Financing depends on occupancy and your profile. For owner-occupants, FHA financing for 2 to 4 units can allow lower down payment if you live in one unit. Review current rules and limits through HUD’s overview of FHA financing for 2 to 4 units. If the property needs work, the FHA 203(k) rehab program may help finance qualified renovations in one loan.
Conventional loans through Fannie Mae and Freddie Mac also support 2 to 4 units. Down payment requirements are often higher than single-family, and they vary based on occupancy and credit. Investors who will not occupy a unit typically use conventional investment mortgages, portfolio loans, or local bank products with larger down payments.
When you compare options, look at underwriting metrics:
- Net Operating Income, or NOI, which is rent minus operating expenses before debt
- Cap rate, which is NOI divided by price
- DSCR, which is NOI divided by annual debt service. Many investor lenders look for DSCR at or above 1.20 to 1.25
- Cash-on-cash return, which is annual pre-tax cash flow divided by cash invested
How to value and underwrite a deal
Start with a simple pro forma. Use the current rent roll, then test it against market rents. Subtract vacancy, management, utilities, maintenance, insurance, taxes, and reserves. Use conservative vacancy assumptions and realistic maintenance and capital expense allowances.
Then pressure-test the numbers:
- Can the property hit your target cash-on-cash return at the expected down payment and rate
- What happens if vacancy rises by 5 percent or if repairs cost more than expected
- Does DSCR stay within lender guidelines across these scenarios
Use three valuation checks to avoid overpaying:
- Sales comparison, using recent 2 to 4 unit comps and per-unit pricing
- Income capitalization, which is NOI divided by a market cap rate
- GRM, which is price divided by gross rent, then compare to similar local properties
Zoning, permits, and compliance in Harford County
Zoning determines what you can legally do on the lot. Before you write an offer, confirm the property’s zoning designation, parking requirements, and any overlay districts through the county. You can start with the Harford County Government site and contact Planning and Zoning for parcel-specific guidance.
If you plan renovations or unit conversions, budget for permits, inspections, and a certificate of occupancy if required. Install and test smoke and carbon monoxide detectors. If the building was built before 1978, follow federal lead disclosure rules, and plan for lead-safe work practices during renovations.
If the property is on septic or well, the local health department may require specific inspections or testing. Flood risk is also critical. Use the FEMA Flood Map Service Center to check whether the property is in a flood zone and whether flood insurance is required.
Finally, review landlord-tenant obligations under Maryland law and check whether any municipality-level rental licensing or inspections apply. Keep screening and advertising language neutral and consistent to comply with fair housing.
Taxes, assessments, and planning
Confirm assessed value and recent tax history early in your process. The Maryland SDAT real property search shows assessment data by parcel. For incentives, some buyers explore state or county programs for rehab or preservation. Visit the Maryland Department of Housing and Community Development for current Maryland housing programs and incentives.
For federal tax planning, residential rental property is depreciated over 27.5 years. Repairs are typically expensed, while capital improvements are depreciated. If you plan to trade up later, a 1031 exchange can defer capital gains when you reinvest into like-kind property. A Maryland-focused CPA can help tailor a plan.
Due diligence checklist for North Hills buyers
Do not skip documentation. Ask for:
- Current leases, rent roll, security deposit records, and lease start and end dates
- Profit and loss statements, bank statements for rental operations, and utility bills
- Property tax bills, insurance history, service contracts, warranties, and maintenance logs
- Title report, easements, HOA or covenant documents if applicable
Inspect what you expect. Line up:
- A general home inspection by an inspector who understands multifamily systems
- Unit-by-unit inspections, appliance checks, and moisture investigation
- Lead-based paint inspection or risk assessment if built before 1978
- Septic inspection or sewer confirmation, and well water testing if applicable
- Metering review to confirm how electricity, gas, and water are billed to each unit
Close legal and financial gaps:
- Full title search and survey if you plan exterior work
- Check for open permits or code violations
- Verify insurance quotes, including flood if needed
- Compare seller pro forma to your own conservative model. Stress-test vacancy and expenses
Operations and value-add strategies
Decide early whether to self-manage or hire a professional manager. Many small multifamily owners pay about 6 to 10 percent of collected rents for full-service management, plus leasing fees. If you self-manage, standardize your screening, documentation, and rent collection procedures to stay compliant.
For leases, many landlords prefer one-year terms for stability. Month-to-month can offer flexibility but may raise turnover risk. Check current Maryland notice rules for rent increases and any local requirements. If utilities are shared, spell out responsibilities in the lease. Where feasible, separate meters can improve cash flow, but plan for permits and installation costs.
Value-add improvements often include kitchen and bath refreshes, new flooring and lighting, and exterior landscaping. Systems upgrades like HVAC, roof, windows, and insulation can reduce operating costs and improve tenant retention. Any conversion or addition should align with zoning and building codes, with permits and inspections completed before leasing.
