Debt to income ratios

[Account Closed]

Need advice from the mortgage lenders out there. I've been looking online but am still having trouble understanding how my current mortgage on my rental will affect buying more properties. The property cashflows approx $600 a month. Will the banks still count my $1300 a month mortgage as debt? Even though I'm not really paying it out of my own pocket. We make about $80,000 a year combined, and no debt except for her $500 a month student loan. We pay $1,100 a month in rent.
