Maine Rental Portfolio Guide
What you need to know before building or growing a rental portfolio in Maine — 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 Maine rentals
Property tax
1.24%
effective rate on median home value
At 1.24% effective, the property tax burden is above the national median (rank 36 of 51). Bake the full annual tax bill into every underwrite; a 2% effective rate on a $400K home is $8,000 a year that has to come out of rent before mortgage.
State income tax
7.15%
top marginal rate
A top marginal rate of 7.15% is high nationally. Rental portfolio income at scale takes a significant state hit on top of federal, so serious operators lean hard on depreciation, cost segregation and 1031 deferral. Long-term hold economics reward staying under the top bracket where possible.
Security deposit rule
State law caps security deposits at 2 months' rent. Charging above the cap exposes the landlord to statutory damages in most states, so build lease templates that respect this ceiling from day one.
Deposit rules change; verify current statute before drafting a lease.
