Why two-families are Watertown's most contested listings
Watertown was built as a streetcar suburb, and its housing stock shows it: blocks of early-1900s two-families within walking distance of Coolidge Square, Watertown Square, and the Cambridge line. Almost none have been built since, so the supply only shrinks — every year a few more are converted to condos and leave the rental stock for good.
That scarcity puts two buyer pools in direct competition. Investors underwrite them on rents that benefit from Watertown's biotech corridor and proximity to Cambridge. Owner-occupants — often first-time buyers using an FHA or conventional owner-occupied loan — bid on them as a house-hack, letting the second unit carry a chunk of the mortgage. When both pools show up at the same open house, well-priced two-families outperform the broader market.
Value is driven by more than square footage: separated utilities, de-leaded units, off-street parking, and condo-conversion potential (unit layouts that map cleanly to two condos) can each move the price meaningfully. Two otherwise similar buildings a block apart can close six figures apart for exactly these reasons.
