Do the math
What would you pay each month for a home in San Carlos?
A typical home costs more than the typical income allows
We start with a typical home in San Carlos, worth $2,000,001, an FHA loan with 3.5% down and the latest average rate (7.18%). That payment would take 82% of the typical household income in San Carlos, which is $237,470 a year. For that payment to be 28% of income, a household would need to earn about $693,267 a year. Note: at that price the loan is above the FHA limit for San Mateo County ($1,249,125), so FHA would not insure it; the payment is only a reference.
The calculator's FHA and conventional loan limits are those of all of San Mateo County.
Change the price, the down payment or the loan: the payment updates right away.
