Refinance in my wife's name only or both our names?

[Trevor Carlson]

My wife and i are going to refinance our primary residence to take advantage of a lower interest rate. We are also going to be buying our first rental property in Columbus, OH in the next few months. We plan on building a portfolio of small multi-family properties over the next five years. I know that financing is easier to get for the first few properties, and I know that by having properties in each of our names we can extend the amount of properties we own collectively at better financing terms.

Is there any disadvantage to having our primary residence refinanced in only my wife's name?

Are there any considerations I am missing?

Other possibly useful information: My wife's W2 income will qualify no problem. I am self employed. We file our taxes jointly.
