Investing in Wilmington, DE — Market Analysis
Wilmington is one of the lower-basis entry points in Delaware, with a median home price around $275,000. As a primary metro, Wilmington gives you the deepest tenant pool in New Castle County — the kind of market where a vacancy is measured in days rather than months, and where lenders are most comfortable with appraiser rent schedules because there are hundreds of comparable leases to draw on.
Buying a rental property in Wilmington on a DSCR loan means putting a minimum of $55,000 down (20% of purchase price), leaving a loan amount of $220,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,538 per month. Add New Castle County property taxes of roughly $133/month and landlord insurance of about $110/month, and your all-in PITIA lands near $1,781/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Wilmington should generate roughly $1,750/month in gross rent. Against a PITIA of $1,781, that produces an estimated DSCR ratio of 0.98x. That falls just short of the 1.0 minimum. This is a very common outcome in Wilmington and it does not kill the deal: moving to 25% down ($68,750) cuts the payment enough to close most of the gap, and several shelves will fund down to 0.75 with a rate add-on.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in Wilmington is around $2,625/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $1,890/month, or a DSCR ratio of 1.06x. On a short-term rental basis the deal clears the threshold, though lenders will want twelve months of documented revenue or an AirDNA/market study to credit it.
Two Delaware-specific items to build into your model: Delaware has no sales tax and among the lowest effective property tax rates in the country, which is a meaningful DSCR advantage. The state does charge a realty transfer tax that typically runs 4% split between buyer and seller — budget for it, because it is far above the national norm. In Wilmington specifically, effective property tax on investment property runs around 0.58% of value annually — about $1,595 a year at the median price — and landlord insurance near $1,320 a year.
On return metrics, Wilmington pencils to an estimated cap rate of 4.73% using a 62% NOI margin, and a gross rent multiplier of 13.1. Monthly cash flow on a long-term lease at 20% down is estimated at $31 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
