Married or not married?

[Virgilio Garcia]

Hello BP i have a question. on finance...

i am single by the law but a spouse at home. 

My spouse and i both have excellent credit and have no personal debt. We will be looking forward to closing on a multifamily property that we will live in while it brings in cash flow to pay down the loan for the property and in time, pull out the equity and invest it again. 

 My question is, I've heard things that people are allowed a certain amount of loans in a lifetime, whether it be a conventional, Freddie mac or Fanine mae, types of loans. so, 

How does not being married or being married affects ones eligibility to qualify for theses or any types of loans? 

P.S. i am in the process of educating my self on REI. Please don't hesitate to correct me where or if i am wrong. I am open to all replies.

Thank you BP.
