In a recent article from HSH.com, a mortgage research website, reports that in order to afford a home in the Los Angeles area of $450,900, based on NAR (National Association of REALTORS®) median home price for 2014 fourth quarter, with 20% down payment, it would take a salary of nearly $90,000.
According to California Association of REALTORS, car.org, median home price for Los Angeles during that same period was $464,650. For the sake of simplicity, I’ll continue with the NAR median price. With a 30 year fix rate (including principal, interest, taxes and insurance, the latter two are variables) and 20% down, monthly mortgage payments would be approximately $2,100. Of course, you could choose to put less money down, but that would change things drastically as it would now include PMI (Private Mortgage Insurance), which would increase your mortgage payments substantially.
