Which one fits
On budget alone, San Mateo is the lower entry point (median $223K vs $240K). Buyers who want newer construction (fewer near-term roof, HVAC and re-plumb items, and easier insurance quotes in Florida) will find it in San Mateo; Sans Souci trades that for a more established street and, typically, larger lots. Sellers get a faster sale in Sans Souci (32 days on market on average); buyers get more negotiating room where homes sit longer.
Neither number set decides it: drive both on a weekday evening, check the HOA documents and the flood zone for the exact street, and price the insurance before you write an offer. A Momentum agent who works both communities can pull the comparable sales for any two specific homes.
