DSCR Loans in Maine: Qualify on the Rent, Not Your Income

I'm based in Maine, and a lot of my DSCR work is here. A DSCR loan uses an investment property's rent to qualify, rather than your tax returns. I compare the monthly rent to the full payment: principal, interest, taxes, insurance and any association dues. In Maine, the local rules on renting matter as much as the rent itself, especially in Portland.

If you are deciding whether this loan fits, I cover the DSCR loan pros and cons and when a conventional loan for an investment property makes more sense. Owners who want equity from a rental without tax returns can read about the no doc HELOC, and the rest of my investor writing is on the mortgage blog. Want to keep your first mortgage and tap the equity instead? See my Maine DSCR HELOC.

Portland caps non owner occupied short term rentals on the mainland. The cap is reset every September 1 at 1.5 percent of the city's registered long term rentals, and for 2026 it's 293 units. Existing licenses carry over only if they renew by December 31. Anyone else goes on a waitlist.

So if you're buying in Portland to rent nightly, don't assume a license comes with the house. I usually underwrite Portland on long term rent, and treat short term income as upside only when a license is confirmed.

Portland also has a rent stabilization ordinance that limits yearly rent increases on covered units. The city sets the allowable increase every September for the next year. It is 2.2 percent for 2026 and 2.6 percent for 2027. If you're counting on raising rents after you buy, that changes the plan, and I'd rather you know before closing.

Bangor is the service center for northern and eastern Maine, with steady demand from the hospitals and the University of Maine nearby in Orono. Lewiston and Auburn have a large stock of older two to four family buildings at lower prices than greater Portland. Augusta has demand from state government. In all three, older buildings mean I look hard at heating systems, roofs and insurance.

Biddeford's mill district has brought new apartments and renters. Farther south in York County, many investors buy seasonal rentals near the beaches. A seasonal property can work, but the rent has to be realistic for a full year, not just July and August, and local short term rules vary by town.

When a Maine investment rental is meant to be a short term rental, I check how that income will be documented before I count it toward qualification. For 1 to 4 unit properties, some programs accept an AirDNA report. The other way to document that income is the current owner's previously reported rental income. I review the property and transaction before choosing the method.

An AirDNA report is not a short term rental license. I check the town's rules separately and review income across the full year, not just the busiest summer weeks. In Portland, if a license is not available, I underwrite on long term rent and treat short term income as upside only when a license is confirmed.

The same distinction matters when you compare a coastal rental with a property in Portland. Income documentation tells me what rent a program may accept, while local permission tells me whether the intended rental use is allowed. My short term rental loan guide explains the broader income review.

Transfer tax. Maine's real estate transfer tax is $2.20 per $500 of price, split evenly between buyer and seller. Above $1 million, the rate is higher.

Security deposits. Maine caps a deposit at two months' rent. The landlord returns it within the period in the lease, up to 30 days, or 21 days for a tenancy at will.

Heating and insurance. Winter heating costs and older roofs drive insurance and maintenance here. If the landlord pays heat, I want to see that in the numbers.

A lease or the appraiser's rent estimate, the tax bill, an insurance quote and the unit count. I finance 1 to 9 unit properties, including condos, but never mobile or manufactured homes. You can close in an LLC or in your personal name in Maine. Lenders still review credit, down payment and reserves, and requirements vary by lender. If you'll live in the property, that's a regular home loan, and I offer those in Maine too.

A 1 to 4 unit rental is the common standard DSCR path, including programs that can use an AirDNA report for short term rental income. That does not limit my Maine financing to four units. I also arrange DSCR loans for 5 to 9 unit properties, including investment properties operated as short term rentals.

I review income documentation for 5 to 9 unit properties separately rather than assuming the 1 to 4 unit approach carries over. My 5 to 9 unit short term rental guide covers that review. These loans are for investment and rental properties, not a primary home or personal second home. Not everyone will qualify.

This is an illustrative example, not a real client. An investor from Massachusetts wants a Portland two family and asks about renting one unit nightly. I check the city's short term rental registry and the cap first. With no license available, I run the ratio on long term rent for both units, factor in the rent stabilization cap on future increases, and add the transfer tax to the closing budget. The investor sees whether the deal works as a long term rental before making an offer.
