Investing in Belmont, MA — Market Analysis
Belmont is a high-basis market by Massachusetts standards, with a median home price around $1,200,000. Belmont is a suburban growth market, which typically means single-family stock, longer average tenancies, school-district-driven demand, and lower turnover cost than urban infill. Suburban DSCR deals tend to underwrite cleanly because the rent comps are homogeneous.
Buying a rental property in Belmont on a DSCR loan means putting a minimum of $240,000 down (20% of purchase price), leaving a loan amount of $960,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $6,712 per month. Add Middlesex County property taxes of roughly $1,140/month and landlord insurance of about $480/month, and your all-in PITIA lands near $8,332/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Belmont should generate roughly $4,875/month in gross rent. Against a PITIA of $8,332, that produces an estimated DSCR ratio of 0.59x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
Two Massachusetts-specific items to build into your model: Massachusetts applies a state lodging excise plus local option tax to short-term rentals and requires registration with the state registry; many Greater Boston municipalities also set a separate, higher commercial tax rate that can apply to certain multifamily parcels. In Belmont specifically, effective property tax on investment property runs around 1.14% of value annually — about $13,680 a year at the median price — and landlord insurance near $5,760 a year.
On return metrics, Belmont pencils to an estimated cap rate of 3.02% using a 62% NOI margin, and a gross rent multiplier of 20.5. Monthly cash flow on a long-term lease at 20% down is estimated at $3,457 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
