3 family under fiances name?

[Sherwin Vargas]

all of our properties have 3 partners (me and my two brothers). We make less but also invest less and also helps keep us grounded with plans. 

 we are thinking of having my fiance apply for financing with me and one of the brothers as a partner. She would get approved she has similar income as my brother who just got closed on a 3 family. We could be risking not having ownership of the house in the future but she also has 2 children with me so I would have her keep the multi if we split up anyways...... is this a bad idea?

It would be me my brother and her as partners so one brother(just bought a single family ) would be left out.  Me and my brothers agreed that if we split up and she kept the house we would manage it for her (make a Little money) but also I would fund the next 3 family on my own and they would be partners. 

Or should we go about it another way? weve been together 5 years and have 2 children but one never knows what could happen. 

we are just trying to get as many 3 families as possible for now and hopefully be able to have 1 or 2 of our wives not have to work full time then save up and try a flip or two with an 'expert' investor friend we have.
