So if somebody committed a felony but they completed whatever restitution was required of them 6 years ago and they have been clean since and otherwise meet your criteria,  is probably pretty safe to consider them.When I still screened and self managed what I found  (small but >1 sample size)  was that applicants who had ONE criminal event in their past but otherwise met criteria were generally no worse of tenant than otherwise equivalent applicants with no criminal history.   

@Ned CareyI was able to upload the title pdf file to my file place for viewing https://www.biggerpockets.com/files/user/Dominik/f...As far as the contract is concerned there is not much info on the website, the files they posted there are samples so I cannot go by them, here are the details:"Transaction Details: Buyer will not be charged a Buyer's Premium for this property.If you are the Winning Bidder, an Earnest Money Deposit of 5% of the total purchase price or $2,500 (whichever is greater) is required.Buyer may receive a Special Warranty Deed or equivalent if Buyer is able to purchase title insurance without delaying the closing (title fees typically cost between $500 and $1500 and are based on the purchase price of the property).

@Anthony Hill That rent is equivalent to the rent she is paying now, she lives a few doors down with the same floor plan.

If you use FHA you can do 3.5% but you have to move in for a year. most likely scenario is the house is not in move-in condition if it's foreclosed and you'll need to purchase it with cash or equivalent. 

It got me thinking of doing something equivalent to a house hack but with a local multifamily property using the SBA instead of the FHA.

@Sam Singh Sam that is the REI equivalent of the Nigerian email scam.

Would you say all three of those are equivalent, or should I choose one over the other here?

Since you don't have any equivalent (AFAIK) that distinction may not exist.

I was able to owner finance a half duplex with very good terms equivalent to what I would receive from a bank directly.

If its empty two weeks a year, that's $4500/2 or $2250 you don't get, or the equivalent of about $200/month over a year..
