What the numbers say about South Portland
A DSCR lender in South Portland is comparing a rent against a payment, and the citywide benchmarks are a median gross rent of $1,812 and a median home value of $441,200. The rent figure is well above the Maine median of $1,139. Dividing a year of median rent by the median home value gives a gross rent-to-value ratio of 4.9%, on the low side, so the payment, not the rent, usually decides whether a file clears. It mixes apartments and houses, so treat it as a compass and not as the number for any one property.

Rules a South Portland landlord should check
For South Portland, treat local rental rules as an open question to close before you offer. Ask the city and Cumberland County about landlord registration, inspections and short-term rental permits, and check association documents too. For South Portland short-term hosts, one state-level point stands out. Maine applies its sales tax to rentals of living quarters, including short-term vacation rentals, and a single unit rented fewer than 15 days in a calendar year is generally exempt unless a professional manager collects the rent.
Maine gives a landlord 30 days after the tenancy ends to return a deposit, an easy deadline to miss without a checklist. Maine rent regulation summary: No statewide cap on the amount of rent; state law regulates notice and bars increases while the unit is uninhabitable.
