. • Inclusion of tenants in the association website with "renter" level access. • Inclusion of tenants in the violation system, including sending notices to them when needed. • Regular monitoring of approved leases to ensure proper actions are taken at the leasing expiration and renewal dates. • Preparation of quarterly reports for the Board of Directors outlining the current status of the leasing program. • Coordination with the Association attorney as needed for enforcement of the leasing provisions. • Assessment and collection of costs for this program from the leased units by the authority of the Community Covenants, Conditions, and Restrictions (CCRs), $150/year.

I personally would rather not have my name or company associated with a contract like that if I wasn't the end buyer. 

Additionally, Parma's proximity to Cleveland enhances its appeal, offering easy access to urban amenities and employment opportunities without the higher living costs associated with larger cities.

There have been some other threads about the US Tax Lien Association here.
