The only cost associated with using the software is a $45 fee that is paid by the tenant to cover the cost of the background check, credit report, criminal history, rental history, and income verification.Using Turbo Tenant is simple and user-friendly.

No offense but the lesson you need to learn from this is that you had the order wrong. 

@Sabrina MaplesIn most cities MF is considered a less offensive and higher and better use than commercial / hotel, so while it will take an architect, surveyors, and the rezoning process it could be possible.

For background/criminal/credit checks I recommend TransUnion Smart Move.

If you do not have a permissible use, you will not be given access to the personal information.In addition to complying with these privacy acts, you should understand that, under the Fair Credit Reporting Act (FCRA) (15 U.S.C. sec 1681), the data provided to you by using the LexisNexis® products may not be used as a factor in establishing a consumer’s eligibility for credit, insurance, employment or other purposes by that act.There are criminal fines and civil liabilities for knowingly violating the provisions and restrictions of these acts.

And that there are criminal penalties involved.

No offense intended here, but central PA just does not seem to have expansion that you see elsewhere.

They provide you with an application credit score, eviction history, and criminal background check. 

Considering the fact that they are otherwise great tenants, I would not evict, but I would word the letter in such a way that they are aware that this is their one and only allowable offense.

If you are unfamiliar with the Landlord Tenant law here are a few examples..Landlord can only charge up to one month rent for a security deposit or “advanced deposit” If tenant with a criminal history is denied the law assumes the Landlord denied this tenant because of their criminal history and can be finedIf tenant leaves the unit before their lease is up the landlord has to make good faith effort to fill the vacancy.
