Since February about half of the syndations marketed through these forums have serious issues that rise to the level of criminal fraud.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

I did 4 fundings in Janesville last year and my guy got through the first one on time and for profit we expected then he up and passed away from a Diabetic coma.. leaving me with 3 that I had to work out of .. two I sold right away for what I had in them one we made a small profit It happens.I do background checks  dont really care to much about credit but I dont want any criminals and then If they are married I want to meet the wife and take them to the nicest dinner in town.

Financially this deal makes sense; however, I am concerned with the safety aspect… I must live there for a year since I am looking for an FHA loan.There are areas close by that i know can have criminal activity but I am uncertain about this specific area (1-2 mile radius).

When it comes to criminal history, that is not a protected class... yet.
