They most certainly could have to comply with Dodd-Frankenstein but if the lender is not in the business of lending, if this is a one off situation, there may not be much reason to be concerned.

Others will comply but will require a ridiculous deposit (I do not recall the city but the deposit they required was ~ equivalent to a year of normal usage).

They complied.

My property started to get destroyed - I raised the rent and asked for a larger security deposit - he complied.

I would advise you look up the tenant laws in the state to ensure you are complying with the law.

Tenant shall not permit any person in or about the premises to deface damage or remove any part of the structure of the premises or the facilities, equipment or appurtenances thereto, nor personally do such things.Tenant shall be responsible for all expenses in connection with any repairs caused by tenant’s failure to comply with the foregoing conditions.

So far she is complying but I also found out why is she complaining as well: her adult son is visiting during the day her quite often bringing his drinking buddies and are making a scene in front of the other tenants cursing and giving everyone dual hand 3 finger salutes.

Just find a contract that complies with Ohio laws.

You run background checks on all adults unless it is a pointless case (example of that is somebody who just moved to the  USA from another country and has SSN - so you could run a credit check with the SSN but it would show you nothing).When you decline an applicant after having pulled a credit report, you have to comply with the FCRA in the rejection letter.

If so, the tenant must comply or be in violation of the lease.
