Consider implementing the Happy Clause.

Long term plans along with the Marion County Landlord registration is to implement Occupancy Inspections and those are waived if Section 8 performs the Inspection. 

The USPS making envelope is an excellent idea that I will start implementing, thanks for the advice again -See You At The Top

@Ehsan Rishat excellent information, will definitely be implementing it right away!
