Maxed on on my 10 fannie / freddie, putting next in wifes name?

[Asher Anthes]

I have my full 10 fannie freddie properties in my name.  I put 1 in my wifes name a few years ago when she had full time income as a nurse.  So, we have a few years tax returns now showing that one rental as hers.  But now, she's not working anymore.  Would I be able to pay her a salary as my property manager, and would the bank look at that as full time income along with the one rental to qualify us for 9 more fannie / freddie loans in her name?

I talked with a commercial loan broker, but all the options have balloons.  My goal is to lock in as much low fixed rate debt for 30 years on good cash flowing real esate.  Would like to have 20 total mortgages in 3 years.

Let me know your guys thoughts, or if you have found other solutuions!
