Delaware is small, but its rental market splits three ways: Wilmington rowhomes and converted houses, Newark student rentals near the University of Delaware, and Dover workforce and military housing.
In short: You can finance a Delaware duplex, triplex or fourplex with a LendingStreet DSCR loan that qualifies on the building's combined rent, with no tax returns. Loans start at $150,000 with no stated maximum, leverage goes up to 80% LTV on purchases and 75% on cash-out, and the standard minimum is a 1.0x ratio with 620 credit. The Delaware items to plan for are the realty transfer tax at closing and new assessments from the recent statewide reassessment.
Wilmington has brick rowhomes and larger houses converted to two or three units in neighborhoods such as Trolley Square, the Highlands, Cool Spring and Little Italy, plus lower-priced buildings on the east side and in the Hilltop area. Many conversions are a century old, so condition varies a lot.
Newark's rental market revolves around the University of Delaware, with duplexes and small buildings rented to students. Dover has duplexes leased to state workers and Dover Air Force Base personnel. Sussex County beach towns have higher prices and seasonal demand, which works better for short-term rental programs than long-term 2-4 unit loans.
Wilmington's prices are generally lower than nearby Philadelphia suburbs, while rents are supported by the city's banking, legal and health care employers.
| Area | Typical 2-4 unit stock | What to check |
|---|---|---|
| Wilmington | Rowhomes and converted houses with 2-3 units | City rental license; older systems |
| Newark | Student duplexes and small buildings | City rental permits and occupancy limits |
| Dover | Duplexes for state and base workers | Steady demand; modest rents |
| Sussex County beaches | Higher-priced seasonal rentals | Flood zones; STR rules |
Every unit's rent counts. The underwriter adds up the leases or market rents for all units, then divides by the monthly payment: principal and interest plus taxes, insurance and any association dues. If the result is at least 1.0x, the building meets the standard minimum; sub-1.0 programs exist for files that fall short.
Your personal income is not part of the calculation. Instead of W-2s and tax returns, the file rests on the rent roll, the appraisal, a 620 or higher credit score, reserves and, if you use one, your LLC documents.
Because the payment drives the ratio, small cost changes matter. A Delaware building that clears 1.0x on the seller's tax bill and an old insurance renewal can fall short once the bill is reassessed and a new policy is written, so price both before you commit.
For decades Delaware counties taxed property on very old assessments, until a court case led to statewide reassessments that took effect in 2025. Many bills changed, some sharply, so use the new assessment and current rates rather than an older bill. Even after reassessment, Delaware's property taxes are relatively low.
The realty transfer tax is the bigger closing cost. Delaware's combined state and local transfer tax is among the highest in the country and is customarily split between buyer and seller. Plan for your share when you calculate cash to close.
This example is illustrative and not a quote. An investor buys a rowhome converted to a duplex in Wilmington for $340,000. Rent is $1,400 per unit, or $2,800 a month across both units. Taxes are budgeted from the new reassessed value.
At 80% LTV, the loan is $272,000, estimated principal and interest is about $1,810, taxes are $200 a month and insurance is $150, for a total payment of about $2,160 and a DSCR of about 1.30x. The duplex clears 1.0x with room to spare. Your share of the transfer tax is part of cash to close, not the payment, but it can be a significant number.
| Item | Amount |
|---|---|
| Purchase price | $340,000 |
| Combined monthly rent | $2,800 |
| Loan amount (80% LTV) | $272,000 |
| Estimated principal and interest | $1,810 |
| Property taxes (monthly) | $200 |
| Insurance (monthly) | $150 |
| Total monthly payment | $2,160 |
| DSCR | About 1.30x |
Inland Delaware properties generally have moderate insurance costs, though older Wilmington rowhomes may need updated electrical or roofing to get good quotes. Sussex County and areas along the Delaware Bay and rivers face coastal flooding, and flood insurance is required for buildings in mapped flood zones. Ask for the flood determination early on any coastal or low-lying property.
Wilmington requires a rental license for residential rental units, and the city inspects for code compliance. Newark requires rental permits and limits the number of unrelated occupants in many units, which affects how much rent a student property can support. Delaware's Residential Landlord-Tenant Code sets statewide rules on deposits and notices, and there is no rent control.
Check the permit status of each unit before closing, especially on converted buildings where the legal unit count may differ from what is being used.
Loan size, leverage and the 1.0x standard minimum DSCR do not change between a duplex and a fourplex. Loans start at $150,000 with no stated maximum, purchases go up to 80% LTV and cash-out refinances up to 75% LTV. More units simply mean more rent to cover the payment and less exposure to any single vacancy.
Small apartment buildings with five to eight units are financed under residential programs too, though leverage can be lower and review deeper, depending on the program. At nine units and up, the loan becomes commercial.

Delaware's combined realty transfer tax is among the highest in the country and is usually split between buyer and seller. Get the exact figure from your title company.
Yes, many bills changed after the statewide reassessment. Use the new assessed value and current rates in your numbers.
Yes, if the units are permitted. Newark's occupancy limits affect how many tenants each unit can have, so we use rent that fits the permit.
Yes. Dover duplexes leased to state employees and Air Force families are a good fit for a DSCR loan qualified on combined rent.
Yes, up to 75% LTV, as long as the combined rent covers the new payment at the program minimum. Seasoning rules vary by program.
No. The loan qualifies on the combined rent of the units. You need a credit score of 620 or higher, reserves and, if you borrow in an LLC, your entity documents.
Yes. An empty unit is typically counted at appraised market rent. Leasing it before closing, or showing it is rent-ready, helps the file.
Our investor loans are business-purpose loans on non-owner-occupied property, so these DSCR programs are not for a building you will live in.
