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.
