What a difference a year makes. In August 2011, I did a mortgage comparison of a 15-year at 3.75% vs. 30-year at 4.75%. Now I’m redoing that same comparison at current market rates of 30 yr @ 3.25% vs. 15 yr @ 2.625%! To be fair, the numbers I used in 2011 were somewhat high.
In any case, the purpose of this comparison to compare the numbers if you wanted to pay down a 30-year mortgage in a 15-year accelerated timeframe, as opposed to just going with the lower interest rate and mandatory higher payment. I’ll be using the mortgage calculators at Dinkytown.
The 30-year at 3.25% would have a monthly payment of $1,305, while the 15-year would have a monthly payment of $2,018. Now, what would happen if we simply paid the $2,018 towards the 30-year mortgage? Using the calculator, we would enter an additional monthly payment of $713. That tells us the 30-year-plus-extra mortgage would be paid off in 15 years and 11 months, requiring 11 additional payments of roughly $2,000 and thus an extra $22,000 of interest in the end. However, the 30-year does allow me the flexibility to reduce my payment by about $700 a month if things get tight. Is the higher cost worth the extra flexibility?
I thought so when I got my first mortgage, but changed my mind once I figured that if I were to hit so hard that I couldn’t make the 15-year mortgage, I probably wouldn’t want to keep paying the 30-year either and would just sell the house and move somewhere cheaper and smaller. I viewed the potential payoff of going with the 15-year mortgage as being to retire one full year earlier.
Lots of people see the low interest rate for the 30-year mortgage and want to use that money to invest in the stock market. That may work out well if you actually invest your money as planned, I don’t know. I personally have enough invested in the stock market as it is, I don’t really want the extra leverage of essentially investing on margin with borrowed money. There is also a chance that the mortgage interest deduction may get capped or phased out over the next several years. That’s a lot of unknowns. I do know a top rate for a long-term certificate of deposit is the 10-year CD from Discover Bank with a yield of 1.90% APY. Meanwhile, the yield on a 30-year Treasury is 2.79%.
In the end, I don’t think there necessarily is a right or wrong answer. There are even more small nuances that went into my decision process, I’ll try and gather those thoughts for next week.
