If you own this as a rental then there is not homestead exemption and you'll pay much higher tax rate than a resident/owner occupant in SC. 

There is no seasoning requirement involved since the property isn't a short sale and it isn't someone buying REO from a bank with a seasoning requirement.

This way if there’s physical damage by residents the company pays the first $500 to fix it.

The most important rule is to have the cash flow of the new property be able to pay all its expenses, mortgage, AND the line of credit back.

And they won’t do it quick just because you want to buy so you would need to close with some estimates on the sale bill.  

It takes that long to pay off your closing costs, rent-ready costs, early turnovers, etc. 

  ( i have owned 3 brokerages over the years and will stand behind those numbers).in the RE training space my thoughts are :5 to 10% of folks that pay for training do anything with it.

The biggest challenge we faced is the property's proximity to a railroad, which has proven to be an impediment to the sale.

If the tenant is claiming to be living in a hotel, she may try to get you to reimburse for that cost unless section 8 has a new process to reimburse them for this... which sounds absurd but I'll let you deduce whether or not you're dealing with someone who is used to paying for things out of their own pocket. 

Namely, that if a tenant (in this case accompanied by a whole family) ends up stop paying rent and I would be on the hook for both covering the mortgage and dealing with open ended legal costs and time.
