Dear Dr. Don,

I can get a loan with 5% down, 0.5% private mortgage insurance, or PMI, and around a 5% mortgage interest rate on a $130,000 home. I have figured that I can comfortably make an extra $300 in additional principal payments monthly and pay down the house below 78% within five years, ending my PMI obligations after it has cost me around $5,000. Or I could save up and make a 20% down payment in about another two years. My questions to you are: Are my calculations correct? And, if so, is it worth waiting to increase the down payment and possibly run into rising home costs and higher interest rates two years from now? Or is the PMI cost minimal enough to make it OK to go ahead with paying the PMI and taking advantage of the low interest rate and current home prices?
Homeowners hate paying PMI premiums because the insurance protects the lender, not the homeowner. But PMI isn't forever, and it allows you to buy today versus waiting until you have a larger down payment.

Paying an extra 0.5% effectively makes the annual percentage rate, or APR, on your mortgage at least 5.5% (roughly). However, when I used a Web-based PMI calculator, I came up with a premium estimate that translated to an annualized rate of 0.78% instead of your 0.5%, so verify your PMI quote with your lender.
Meanwhile, a mortgage interest rate of 5% is more than a full percentage point above Bankrate's national average of 3.97% for a 30-year fixed-rate mortgage. If you have a good credit score, you shouldn't have to pay 5% on a mortgage, even with a low down payment. With the PMI policy, you're insuring the lender's risk from your low down payment. You don't need to pay twice for that risk by paying PMI plus an above-market interest rate.
I don't know your real estate market, but I'd say odds are you're better off buying now with a low down payment and PMI than waiting a couple of years to build up your down payment to 20% of the purchase price, so you don't have to pay PMI.
Again, you don't have to be stuck with PMI long-term. Making an additional principal payment of $300 a month will get you to well below the 78% loan-to-value level where the lender has to cancel the private mortgage insurance policy after five years.
If you apply to several mortgage lenders to try to get a better interest rate, do it over a very short period of time (two to three weeks) so your credit score isn't hurt by multiple inquiries. When you do that over a short period of time, it's viewed as comparison shopping, and your credit score doesn't take a big hit.
