@Aaron Zimmerman HubSpot is a great CRM to use at a low cost.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

On the flip side the clients I fund in my land deals are doing very very well in the foothill subdivision 50 miles or so west of the springs.. but thats the land game buy low sell high.. cant wholesale that stuff it needs to go on MLS to marketed and turn around time is generally 90 to 180 days but nice margins for my clients ..

The real estate prices are relatively low, compared to the cities & more touristy areas, but the rental returns are good, with a low vacancy rate.

I am betting you didn't put this (or the other ones) home on the market to then become the bank for someone who only has a couple thousand down and no credit instead of selling to a verified buyer, right?

There are a few others here on bigger pockets who have endeavored to do so and can attest to this  (but I will not name them).Basically AHP bought 1000s of low value non-performing loans, these require the most oversight mainly due to the condition of the properties. 

And Sec8 sounds great, but comes with it's own issues.Add it all up you get a low dollar, but high headache strategy, which is a challenge that gets amplified, especially when you are operating remote.

218K seems a little low for the area.

Population growth, job diversity, and low DOM (days on market) are significant indicators.

Look for properties with low taxes, separate utilities, strong demand, and potential for rent increases.
