Refinance when going to sell?
When evaluating a refinance, it all comes down to the payback. Refinancing costs money in closing costs. There are different reasons for refinancing, and they all have different methods for calculating payback.  One reason to finance is to get a lower interest rate. When determining the payback time, you calculate how long it would take to recover your closing costs with the amount you save in interest. For example, if the closing costs are $2,000, your payback time is 2 years if it takes 2 years to save that amount in interest with the new interest rate vs. the old one. The longer you hold the mortgage after you refinance, the more money you save in interest with the new rate. Generally, it doesn't pay to refinance to a lower rate right before you sell, because you aren't holding the mortgage long enough to see the interest savings. You seem to be 3 years away from selling, so you might be able to see some savings here in the next three years.  A second reason people refinance is to lower their monthly payment if they are having trouble paying it. I see you are considering switching from a 15 year to a 30 year; is one of your goals to reduce your monthly payment? By refinancing to a 30 year, you'll be paying a lot of interest in your first few years of payments, extending the payback time of your lower interest rate.  A third reason people refinance is to pull cash out of their equity. This applies to you as well. Since you are planning on using it to remodel the home you are trying to sell, you have to ask yourself if the renovations you are planning will payoff in the increased sale price of your home. Often, renovations don't increase the value of their home as much as they cost. You do renovations because you will enjoy living in the renovated home, and you get some of your money back when you sell. But sometimes you can increase the value of your home by enough to cover the cost of the renovation. Talk to a real estate agent in your area to get their advice on how much the renovations you are talking about will increase the value of your home.
