https://www.trulia.com/for_sale/San_Mateo,CA/I think that's fair but the nonetheless the only houses on here in San Mateo for under 600k are about 600sq ft. Even 1200sqft homes are 1M+ Where do you think married mid-level engineers are going to live?
For 500k in Austin you can choose between brand new 1300 sqft homes or older 2500 sqft homes.
