San Francisco real estate buyers snap up bargain underwater lots for under $1000

May 24, 2026 - 06:51

A trio of vacant lots in San Francisco recently sold at auction for less than a thousand dollars apiece, a price that sounds like a steal until you realize the land is completely submerged. One of the parcels, a 5,000-square-foot plot near Candlestick Point, sits entirely underwater at high tide. The sales have raised eyebrows, but some real estate experts see them as more than just a quirky footnote.

The buyers are gambling on a long shot. Filling in the land to make it buildable would require a costly and legally complex permit process from the Bay Conservation and Development Commission, which tightly regulates any changes to the shoreline. Another possibility involves constructing floating homes or docks, though that also faces strict environmental review. For now, the lots are essentially underwater storage for mud and silt.

Critics call the purchases a waste of money, even at such a low price. Property taxes and liability concerns could quickly eat into any theoretical profit. Yet for a certain type of investor, the gamble is part of the appeal. If the city ever relaxes its waterfront rules, or if sea levels rise enough to change the legal definition of the land, those $1,000 lots could become prime real estate. Until then, the new owners hold title to a piece of the bay.
