Delaware Rental Portfolio Guide
What you need to know before building or growing a rental portfolio in Delaware — property tax burden, state income tax, security-deposit rule, source-of-income law, and the metros that actually cash-flow after accounting for local taxes.
Tax burden on Delaware rentals
Property tax
0.61%
effective rate on median home value
At 0.61% effective, this is one of the lowest property tax burdens in the country (rank 10 of 51). Portfolio holding costs stay low even in appreciating markets — a big structural advantage for long-term holds.
State income tax
6.60%
top marginal rate
A top marginal rate of 6.60% is moderate. Portfolio income above the federal deduction stack still faces this rate on top of federal, so tax-optimized holding structures (installment sales, 1031s, cost-segregation) matter more here than in no-tax states.
Security deposit rule
State law caps security deposits at 1 month' rent (with the qualifier noted below). Charging above the cap exposes the landlord to statutory damages in most states, so build lease templates that respect this ceiling from day one.
Note: unfurnished, non-mobile; furnished may exceed
Deposit rules change; verify current statute before drafting a lease.
