But one of the PM that we spoke about told us that from his experience relatively cheap houses ( he was saying that single family house  whose rent is lower than 1000 dollars is in the category cheap) attract people with low salary, and that basically then are barely surviving, which means that if they have any serious problem in their life, child sickness, car being broken down, tooth problems, they will not be able to pay, which will lead to either slowing down of everything, or them not paying at all, or not even wanting to move out, an then he layer and just losing the money.  

A and B are confusing.

If you're barely paying P&I, I would suggest raising the rent, and decreasing landlord costs.

I’ve been pouring my extra money into my current mortgage and now that I’m ready to buy #2 I have barely any cash to put down.

No stairs, pink & yellow tile, shag carpet, floral wall paper padded toilet seats. 

If you are advertising in the right places (everyone seems to agree that Craigslist and Zillow are the bare minimum), you WILL get tenants.3) Screening still matters.

In the Denver metro to Boulder there is no limit on pricing houses sell at almost all price points,the average new construction house in the metro is around $500k last I read - there is just not a market for the price point it takes to make sense in the smaller/lower priced areas.It says a lot about an area when rents are going up quickly and prices are barely following - rent of $1,100 amount buys a nice house in the areas you mentioned in Southern CO.

So, even the applicants who barely meet your requirements may seek alternative means to live someplace else- even if it means being dishonest to do so.I think you're wise to go with a voucher program given your description of the place, but I would suggest modifying your requirements to obtain a better quality resident.

We have high taxes in CT, yet I'm satisfied with my ROI on houses that barely break the 1% rule.

So you can see we are basically barely meeting demand, if that, as prices continue to appreciate.
