Refinancing in a partnership

[Ethan Ducharme]

My partner and I are in the processing of refinancing our 4plex and are wondering if there is benefit in just one of us being on the mortgage. We are going to continue to work together in the future and are wondering if it makes sense to just have one of us on the loan. If so can we still have both of us on the title, and just one on the loan, or only one on the title? Is there anything we should do to protect my interest if I were not to be on the loan or title outside the JV that we have in place? He has several properties by himself, and with another partner. This is our first together.

I also don't own a primary and currently rent, yet my buying power has increased due to the income of our 4plex. I would like to maintain that "on paper" buying power and am curious if that goes away if im not on the mortgage, title, etc. 

Thoughts!?
