No tenant would ideal for me.

In my opinion, the ideal is to be the second owner (2-5 years old).

One for Tennessee would be ideal.

@Dimple Khurana there are also other factors outside of liens that could be problematic if you're bidding sight unseen such as a leaking oil tank, foundation issues, etc

I know gaining trust is a key factor in making them feel comfortable with their investment, but again it is more difficult for someone to feel comfortable with you when you have only met via video chat. 

A downstairs unit and an owner open to having 2 cats would be ideal.  

I have it described as this:"Split floor plan is ideal for roommates with a master suite on each end or privacy for a new family."

You may also want to factor in the education from investing versus not.Thoughts @Michael Lee @Andrew R.

They ruin roofs left and right and your insurance is higher.You can use a turnkey provider or find a local agent/ pm and go that route if you go out of state.I have done both and think a combination is ideal.

I am always watching rents in the area though, frequently looking at trulia/padmapper/apartments.com/zumper/craigslist ads and snap a photo of every "for rent" sign I see to call up and find out.There is a lot more variation than simply how many bedrooms a place has and where in the city it is located in, property condition, layout, density, and the environment around it factors into the price a lot, and rentometer doesn't give you much insight into that.
