@Jaz Patel Grant street group is one company that that runs sales for counties across the country. 

HI @Daniela Craig  Find out why the property is for sale so that the offer answers to the Seller's needs.  

I buy a lot in the Pittsburgh sale so here is what we do and I hope this helps.

If you're parents are going go receive any money from that then they will have to take depreciation then on that property and it will appear on their schedule E as well (upon sale they have to recapture any depreciation they took or could have taken so watch out for that).If you go further the route @Corby Goade suggests with a deeding you'll want your accountant to advise on gift tax consequences or use of the one time limitation. 

A property of that price is going to be a tougher sale for a flipper since they typically stay on the market longer once completed and it's a lot of capital to tie up.  

TIAWaterfallUpon sale, proceeds will be distributed in order as follows.

It is for sale by owner. 

Just like any other business its all about sales and most importantly MARKETING!!!!! 

It also reinforced my thoughts that a clean sweep sale and a 1031 into better performance would be a good plan. 

Can I remove them once the sale is complete, do I have to evict them, can they be forced out due to the living conditions?
