mortgages in wife's name

[Mark Baldwin]

So I'm considering to refinance my home (I could comfortable afford the new payment) and pull out some cash in order to quickly scale in the SFR space. My wife and I file taxes jointly, though almost all of our income comes from me. Will she still be able to get 10 mortgages in her name, while I get 10 in mine? Or will she not show enough income to qualify for her 10? Thanks for the help!
