High DTI - how to scale rentals?

[Andrew T.]

Buying the first rental is easy, second one is a little tougher, how do you get beyond?

For example, if you've saved for 20% down, bought your first home, rented it out and refinanced, used the refi $ to purchase another property, how do you get to the third if your income can only withstand a certain DTI ratio. Or, if you are able get to the third, how do you get to the fourth? Your DTI would be maxed out even if lenders are taking into 50-80% of rental income with offset. What's the process to secure mortgages without private, creative lending?
