Kumiko just did a blog post on this that I read on The Budget Mom Facebook page about whether or not to refinance! If you’re planning on staying in the house, then refinancing is probably a great decision. When you refinance, like you said, there are closing costs all over again so it usually puts your loan back at a higher starting point. But with lower interest, over time it’ll be totally worth it! We had the opportunity to refinance, but due to relocating have to sell our house within the next year so we said, NO. because it’s bump our loan back up like 8, 000, so when we went to sell, we’d possibly not even break even. Lol so it just depends on your circumstances. But If the loan is only going up 4500 and you plan on staying in the home for the long haul, a lower interest rate and refinancing will eventually save you so much money!
