Starting out with 2 primary residences

[Shelby McKean]

My husband and I live in two different cities with 2 houses.  One has a low interest rate loan and the other does not.  If I am starting out as a real estate investor interested in being a rental landlord (still working out the main type of rental I want to work with), can I refinance the house with a higher rate and make it a rental to my husband as my first rental?  Also, what situation is the best thing for our taxes?  We file jointly, but I want the investing to be my business in my name.
