A customer of mine mentioned she is selling off all of her properties as she is 80 and looking to enjoy the rest of her life task free. 

In this day of housing shortages and rising rents, you mentioned you don’t want to deal with all the “Covid19 no eviction garbage,” yet you’re ok creating a facility specifically designed to encourage others to congregate during a pandemic?
