When trying to grow, cash flow isn't your concern. 

My concern is if you don't know the lease goes with the property, what other important legal details are you missing.

When I get a colleague request from someone, most of the time, its accompanied with a message so I know first who they are, and second why they are reaching out specifically.But sometimes, I get a colleague request from a name I know nothing about... not sure if they reached out related to a forum post, or if they want to pitch me on something that I may or may not be interested in.Kind of reminds me of LinkedIn, where my approach has always been I don't connect with any random person, only those that I have either met in person, or have interacted with in some business sense.

I have my property manager dealing with him and going over my concerns and I'm supposed to hear something back today.

There isn't anything structurally wrong with them where I'm concerned about the foundation.

Yes, but we are concerned about ESA dogs, and if a homeowner of a single family house who rented without help of a realtor can refuse ESA dogs. 

However what the bank would be concerned with is your cash flow and debt to income ratios.

@Buyan ThyagarajanI would be more concerned with the size of the renter population for 2-bedroom homes versus 3-bed properties.  

Has anyone done this and what should I be concerned about with this?

Try section 8 tenants for rental guarantee if you are concerned about the rougher areas.
