Investing in Waltham, MA — Market Analysis
Waltham is a high-basis market by Massachusetts standards, with a median home price around $800,000. Waltham is a college-town market. Student and faculty demand creates reliable occupancy, but leasing is seasonal — most of the year's placements happen in a narrow summer window, and per-bedroom leasing often produces more gross rent than a single whole-house lease.
Buying a rental property in Waltham on a DSCR loan means putting a minimum of $160,000 down (20% of purchase price), leaving a loan amount of $640,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $4,475 per month. Add Middlesex County property taxes of roughly $760/month and landlord insurance of about $320/month, and your all-in PITIA lands near $5,555/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Waltham should generate roughly $4,525/month in gross rent. Against a PITIA of $5,555, that produces an estimated DSCR ratio of 0.81x. 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 has strong tenant protections and a judicial eviction process that routinely runs several months, so vacancy and legal reserves matter more here than in most states. The Cape and Islands operate on a compressed summer season that concentrates most of the year's short-term revenue into roughly fourteen weeks. In Waltham specifically, effective property tax on investment property runs around 1.14% of value annually — about $9,120 a year at the median price — and landlord insurance near $3,840 a year.
On return metrics, Waltham pencils to an estimated cap rate of 4.21% using a 62% NOI margin, and a gross rent multiplier of 14.7. Monthly cash flow on a long-term lease at 20% down is estimated at $1,030 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.
