Help with creative refinancing

[Jacki O]

I bought my townhouse 4 years ago with a 5 year arm/interest only, in hopes of flipping it within that period. Over the last 4 years, I met my husband, got married and moved into his house. Selling the property has been a challenge, but I've been successful in renting it out for the last 2 years. I never let my mortgage company know about the rental. The arm expires this June. I looked into refinancing it to a 30 year fixed, however, the mortgage company gave me a really hard time as to why the property address does not match mailing address. I don't want to refinance it as a rental property, as the APR is at a higher rate. What would be the best way to approach the refi with the mortgage company to allow them to do it at an APR for a primary residence?
