Looking for advice on how to finance to mortgages

[Christian Angel]

I currently own a home with my wife in Orlando, Fl. It's our first property financed through FHA under her name. We are looking to upgrade and buy a second home as our primary residence and convert the first home into a rental.
What is the best way to qualify for two mortgages? 
Can I qualify for an fha loan since the first home is only under my wives name?

Can I use the potential rental income form the first home to help with the debt to income ratio?

Thank you in advance.
