California is progressive. A married couple with 100K combined income and $1500/month in mortgage interest payments will pay $3500 in state income tax. A married couple with 60K combined income and $1500/month in interest payments will pay $1000. If they were fortunate to buy in 1980’s or 1990’s, their property tax can be as low as $1000/year.
Texas is regressive. There’s no state income tax, but every homeowner, regardless of income (unless he lives in a condo or a trailer park), will pay 5K+/year in property taxes, and many will pay 8-10K.
