So my wife and I live in Northern Virginia (NOVA), and we are looking at moving out of the area in the near future. Due to the nature of our professions, we will very likely be back sometime in the future, and the way houses tend to appreciate in this area, it seems like a mistake to sell. We're committed to holding onto the house, so we'd like to rent it out after we move. The problem is that rental estimates show that we could expect to get $2400 a month for our place, and our monthly expenses on the house come to around $2500. We've been making payments on it for 5 years, and by now I have enough equity in the house to refinance and bring the monthly rate down to $1700. Considering that we're against selling it, it seems like a good move to me to turn the house into a cash-flowing asset by refinancing it rather than putting money into it every month just to hold onto it and build equity.
Is this a good idea in principle, or is there something that I'm not taking into consideration?
