Also, any best practices for room rentals that you recommend for screening and keeping tenants.

This is too important and also sort of a personal question depending on your state and specific circumstance and I suspect not a one size fits all answer would suffice. 

As far as property type, for flips I like middle sized houses, 3/2 around 1500/3000 sq ft but not married to that.

They filled out the application through apartments.com (used to be Cozy.co before it was acquired) where my screening criteria is posted and the application is hosted, and their annual income listed in the application is 1.25x rent.

- Tenant Screening for Pet Owners: What criteria should I use when screening potential tenants who have pets?

He enjoys the cash flow, has a good tenant screening process, and is OK with the tenant headaches that are going to occur.I would put it higher on the reward side of the profile, but it also is a higher amount of work and harder to scale endeavor.

A nice but rental quality unit gets 1500-1650 regularly in that area depending on the size and finishes.

Last questions, can't a voucher holder apply to any home of any size in their approved area? 

Apologize if these questions are vague, I am quite new to this.Happy to provide some of the data I have found thus far (though data online is scarce given the size of the town).Thanks!

You should screen everyone the same, but still, it's a bit of a comfort knowing FF is mostly all working professionals.
