Should You Refinance?
When I purchased my home two, nearly three, years ago, I had a great interest rate of 5.75%. With the recent Fed rate cut of 0.75%, a question that has been swirling around the heads of my friends has been whether or not they should be refinancing. Some of them have loans at higher rates or HELOC’s and 2nd mortgages at higher rates - for them the analysis is worth performing. As for us, with the Bankrate quoted rates at around 5.40% for a thirty year mortgage (under 5% for a 15 year mortgage), the answer for us is unclear… this calls for an analysis!
Comparing Total Interest Payments
The current outstanding balance for our mortgage loan is approximately $224k and, given minimum payments for the remainder of the loan, puts us on pace for paying out a total of $217k in interest and $224k in principal. The $224k in principal is given, what interest rate do I need in order to pay less than the $217k in interest? According to the calculators at Dinkytown.net, the answer is approximately 5.16% on a 30 year mortgage. This analysis does not include closing costs, some of which I would be responsible for even if the lender paid for the closing costs (at the very least, I’d have to pay the scam that is title insurance). In actuality, on a 30 year mortgage, I would need something that’s slightly less than 5.16%.
Lower Monthly Payment
Another consideration, if I were to get the break even mark of 5.16%, my payments would be $1,200 for 360 months - approximately $200 less than our current payment. If I felt that the extra cashflow was necessary, I would definitely go for a refinance if the numbers were right. As it were, we are currently paying extra each month (approximately $300) so that the 30 year mortgage is closer to a 15 year mortgage. Having a lower payment but paying more gives us the flexibility to treat it like a 15 year mortgage but only be obligated for a 30 year, should our cash flow situation tighten up.
What If? The 15 Year Mortgage
What if we went with a 15 year mortgage? Let’s say we could get a 15 year mortgage at 4.875% (Nickel just locked in this rate) on my balance of $217k. The monthly payments would increase to $1750 each month (or $150 less than our current actual payment) but the total interest paid would plummet from $190k (the amount given the $300 extra paid) to $92k, nearly a hundred thousand dollars. Am I willing to save $100k (it’s really only a $75k savings given taxes) and lock in the $1700 per month payment? That’s a much harder question to answer.
Summary
Refinancing to a fixed 30 year mortgage doesn’t appear to be make much sense but refinancing to a fixed 15 year mortgage, given our extra principal payments, looks to save us $75k over the loan period. These all assume that there will be no closing costs but would I be willing to pay a little extra in front in order to get some savings in the long run… perhaps. I have to think about this some more, please share your thoughts in the comments and please tell me if I’ve done my math wrong!
Next Steps
I think the next step for me is to take a look at Lending Tree, where I like to go to get a quick snapshot of what’s available. When I bought the first time, I used Lending Tree to get a pre-approval letter and to help me get a better handle on what rates would actually be for me. They gave me a good snapshot, so I’m going to use them again to get a feel for what’s out there.
