Since I have been through 3 refinances on the same home, I pretty much know the ins and outs of refinancing a mortgage. I have had fixed rate, adjustable rate, and even a second mortgage at one time to pay off debt.
With my second refinance I had gotten the house in the divorce, and had to refinance to keep it. Naturally, a quitclaim from my ex was required, and all the paperwork for refinance was my biggest headache. Thankfully, I had a very good broker helping me along the way.
The only costs I incurred was the appraiser. Other than that I had a no closing cost refinance.
If you are thinking of refinancing your home, beware of closing costs that can cause more added expense than necessary.
If at all possible, ask about a no closing cost refinance. If you do not qualify for that, ask if the costs can be rolled into your payment, or at very least get the best prices on the loan application, attorney fees, land survey fees, title search and insurance fees, home inspector fees, and appraisal fees.
Drawing from my own experience, the one fee that must be paid out of pocket at the time of service for refinance is the appraisal fee.
