Conventional financing and the DTI ratio

[Nick Walters]

My wife and I are having a discussion about the ability/inability to acquire 10-12 single family properties in 5 years. Her strategy is to pay down our first property considerably before buying another one, and my strategy is to buy as many as possible and use our current income to leverage more properties.

We have a combined gross income of 250K and FICO scores north of 700 and are looking at properties in the 200-350K range in MA.

I am not clear on the debt to income ratio and the role rental income plays in acquiring more properties.

With the above figures (and provided my and my wife's risk tolerance reaches a middle ground), are there challenges with us acquiring multiple properties/year with conventional financing?

Thanks in advance for all your feedback.
