A plain-English guide from How Big a House Can I Buy?
Los Angeles affordability is a study in opposites: thanks to Prop 13, LA County's effective property tax is low (~0.7%), but California's income tax is the nation's highest and SoCal home prices demand big loans. The result: your after-tax income and down payment drive the answer far more than property tax.
A worked example: a couple earning $350,000 on the Westside with $300,000 invested, keeping a $60,000 cushion, on a 30-year fixed at 6.5%, models out to roughly a $1.1M home with about $110,000 down and a payment near $7,000/month — and a wide range around it: about $590k if they protect their full $1.5M wealth goal, up to about $1.6M stretching. In much of LA, Orange County, and greater Southern California, that stretch scenario is what it takes to buy in the neighborhoods people actually want.
