Quote from @Juliet Silver: It may be an investment, the buyer is working on a variety of scenarios now.

Those are tiny, tiny obstacles compared to where this process succeeds or fails, and that is with the contracting. 

for double closing you would need your funds to buy then sell it to end buyer at premium. there are transactional funding companies that can lend the cash for a fee.

Again, ive done some research and only look at the areas that are most desirable to renters, which typically lines up well with the areas most desired by buyers.

I would pay for a buyers agent who did the paperwork.  

More frequently these tax sales are overturned on the grounds of failed or improper notice procedures.

Because that is still your property that you found, you can find a buyer.

They seemed really intent on buyers creating a criteria before getting properties sent to them.
