Financing strategy for BRRR

[Steve Swanson]

I currently have 4 conventional loans in my name (3 Cash flowing SFR, and 1 personal home). I have a new property that I bought for cash, have held for 4 months, and am starting to look for my next mortgage that I'd like to close shortly after I hit the 6 month mark. Since I'm at 4 loans, I wanted to see what terms I'd be looking at (LTV, rates, etc). I have excellent credit, and DTI <30%.

I also wanted to see if it made more sense for me to pursue getting my 5'th mortgage, or having my wife get her 1'st mortgage?  My wife also has excellent credit, but she's self employeed & only shows $2-3k of income on her own, but we file a joint Tax return, so I think we can include my income on her application, but this is where I need some guidance. Would it be better for me to get my 5'th loan, or her getting her 1'st if she could get approved.
