Investment property refinance following a low appraisal?
The new payment on $172,500 3.5% 15yr would be $1233/mo compared to $1614/mo now (26 bi-weekly payments, but 12 months.) Assuming the difference is nearly all interest, the savings is closer to $285/mo than 381.  Note, actual savings are different, the actual savings is based on the difference in interest over the year. Since the term will be changing, I'm looking at cash flow, which is the larger concern, in my opinion.    $17,000/285 is 60 months. This is your break even time to payoff the $17000, higher actually since the $17K will be accruing interest.  I didn't see any mention of closing costs or other expenses. Obviously, that has to be factored in as well.  I think the trade off isn't worth it. As the other answers suggest, the rental is too close to break-even now. The cost of repairs on two houses is an issue. In my opinion, it's less about the expenses being huge than being random. You don't get billed $35/mo to paint the house. You wake up, see too many spots showing wear, and get a $3000 bill. Same for all high cost items, Roof, HVAC, etc.  You are permitted to borrow 50% of your 401(k) balance, so you have $64K in the account. I don't know your age, this might be great or a bit low. I'd keep saving, not putting any extra toward either mortgage until I had an emergency fund that was more than sufficient. The fund needs to handle the unexpected expenses as well as the months of unemployment. In general, 6-9 months of these expenses is recommended.  To be clear, there are times a 401(k) loan can make sense. I just don't see that it does now.  (Disclaimer - when analyzing refis there are two approaches. The first is to look at interest saved. After all, interest is the expense, principal payments go right to your balance sheet. The second is purely cash flow, in which case one might justify a higher rate, and going from 15 to 30 years, but freeing up cash that can be better deployed. Even though the rate goes up say 1/2%, the payment drops due to the term. Take that savings and deposit to a matched 401(k) and the numbers may work out very well.  I offer this to explain why the math above may not be consistent with other answers of mine.)
