I just stubbled upon mysmartmove, it charges the applicant $25 to $40 for an extensive screening which includes; credit score, criminal background, eviction history, and bankruptcy.

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.

The criminal background check came up clear but I found out that the male tenant had case against him that caused him to loose his job at the school due to inappropriate behavior.

Hello,I was wondering if anyone knew any trustful websites (preferrably free) which provide tenants background check report service including felony/criminal charges.

That increases cash flow comes with substantial more risk of tenants not paying, tenants causing significant damage, and potential criminal activity.

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.

As long as they don't have any evictions, major crimes on their record, and an acceptable credit score / history, I'll then do the next level digging.Zillow won't always give you the details you need about a criminal charge, so you'll either need them to provide documentation regarding what the charge is, or get a background check.I'll typically ask for copies of pay stubs or bank statements to verify income if they didn't already upload them to Zillow.

SEC 8 ONLY screens for criminal. 

For example, by making it clear that every adult will have to pay $30 and submit to a credit/criminal screening, you will probably eliminate 1/4 - 1/3 of these applicants.

Zillow may or may not be fine for that, but you never should stop with the credit report and criminal check.
