Maine tax sale investing: buy the property itself at the county sale

How it works in Maine

In Maine the county sells the property itself at a tax deed auction. Win the bid and the deed is yours — along with the due diligence burden, because sales are as-is and buyer beware.

Interest / penalty: n/a — no tax lien certificate is sold to investors, so no investor interest rate applies; delinquency interest is owed to the municipality at its voted rate, capped at the State Treasurer's maximum of 7% for 2026 (36 M.R.S. § 505)

Redemption: 18 months from filing of the tax lien certificate in the registry of deeds (36 M.R.S. § 943); if unpaid, the tax lien mortgage is deemed foreclosed automatically and redemption expires

When sales happen: No statewide investor sale and no county tax deed auction; municipalities sell tax-acquired property after foreclosure, as needed year-round

Where sales run: municipality-specific — tax-acquired property must generally be listed with a licensed real estate broker (36 M.R.S. § 943-C), mostly in-person / broker listings, no statewide online platform

Governing law: 36 M.R.S. §§ 505, 942–943, 943-C (tax lien mortgage and sale of tax-acquired property)

The investor's edge

Your edge is the max bid: value the property from county records and recent sales, subtract title-clearing and repair reality, and write the number down before the auction opens.

Maine sells no lien certificates: the municipality holds the tax lien mortgage itself, forecloses automatically after 18 months, and since Aug. 9, 2024 must generally sell the tax-acquired property through a licensed broker at the highest reasonable price, paying any excess proceeds to the former owner. The older tax-sale deed procedure at §§ 1071–1078 (2-year redemption at 8%) is not the main modern investor route.
