Common questions

How much do I need to make to buy a $400,000 house in California?

About $101,958 a year at the 28% front-end ratio, with 20% down and a 6.65% thirty-year fixed. That covers a $2,379 monthly payment: $2,054 principal and interest, $233 property tax and $91 insurance. Lenders who stretch to a 31% ratio would accept roughly $92,091.

What is the monthly payment on a $400,000 house in California?

Roughly $2,379 a month with 20% down and no HOA. With 5% down the payment rises to about $2,986, because the loan is larger and PMI adds around $222 until the balance reaches 80% of value.

How much are property taxes on a $400,000 house in California?

About $233 a month, or $2,800 a year, at the 0.70% effective rate this state averages. County rates vary around that figure, and assessed value here cannot rise more than 2% a year, so a long-held home is taxed on far less than it would sell for.

How much cash do I need up front for a $400,000 house in California?

$80,000 for a 20% down payment, or $20,000 at 5% down. Closing costs typically add 2–5% of the price on top, and lenders will want a couple of months of the $2,379 payment in reserves.

This is a price point, not a house. Put in an actual California address, the date it closed and the price paid, and the calculator works out that home's payment, its mortgage-insurance dates and the equity behind it.
