VA Refinance Question

[Brenden Scott]

Hello BP community! I am a military member and will be moving in about 15 months. I own a townhouse financed through the VA at 3.25% 30yr fixed. I have the opportunity to refi to 2.75% fixed 30yr, will no out of pocket costs. Cost will be $3890 to refi and rolled into new loan. Monthly savings will be $128. I understand the recoup period calculation (loan cost/monthly savings) for a refi. My calculation tells me it will take 2.5 years to recoup and since I would like to ideally sell in 15 months, it seems better to stick with what I have at the moment.

But should I be considering the cash flow I will save by not paying the interest on my mortgage for two months while a refi is being completed? My broker says we can skip two months of payments (P&I). I don't think I should count the missed principal payments as cash flow because that is in effect reducing my equity in my property, but what about the interest I would not be paying for those two months? Two months interest I don't have to pay, plus the monthly savings of $128 over 15 months will be more than the costs to refi. Am I thinking about this right?
