The subject property at 67 Walnut St is a classic two-family home with a total of 5 beds and 2 baths across 2,400 sqft, well above the Watertown average unit size. Based on nearby comps and current market data, the estimated rent potential is between $6,150 and $7,435/month for both units combined, depending on finish quality and unit configuration. Payback period (gross) lands around 12–15 years given the asking price and projected revenue. The Watertown rental market is tight—vacancy is below 1%, and rents are expected to trend upward through the end of 2025. The property’s updated systems, two-car garage, bonus sunrooms, and proximity to Arsenal Yards provide strong appeal for renters, but older layouts may limit top-dollar rents unless further modernized.

To maximize rent, consider cosmetic upgrades to kitchens and baths, and possibly reconfiguring layouts to add an additional bedroom or bath per unit if feasible. Adding washers/dryers in-unit, enhancing curb appeal, and highlighting the garage and bonus rooms in listings could further boost desirability. If selling, market the property’s value-add potential and its location near transit, shopping, and top-rated schools, as investors are keen on Watertown’s low vacancy and rising rent trajectory.
