How to obtain a second mortgage

[Xu Som]

HI BG community,

I recently got married and me and my wife are searching for a house. We are currently living with my family and the house is under my name. 

Since I have a mortgage already, is there another way for me to obtain another mortgage if we do find a new house? Me and my wife plan to have our names under this new house when we find one. 

Would the family house have to be refinanced to take my name out and add in some of my family members instead? 

Can I list the family house as a rental?

Any other ways for me to qualify for a new house?

Thanks in advance!
