Seller taking a loss and tax implications

[Account Closed]

Working on an unfortunate situation with a seller who paid more for the property 12 years ago than I'm able to offer today - they bought in 2006 and probably overpaid, then did not maintain the property, and then got behind on property taxes so there are a lot of penalties/interest. Seller is concerned with any taxes they may have to pay by selling the home, since they are already taking a loss. My guess is that there will not be any tax due, given the loss, but I wanted to confirm - obviously every situation is different but just looking for general advice. Also I know there are creative tax strategies but these folks are low income and are not going to have a fancy accountant working with them when tax time comes - so just looking for some realistic advice/general info I can pass on to point them in the right direction.

For the sake of having numbers let's say they bought for 40k, property is paid off, and after the sale they will walk away with only 30k. Given they are selling at 30k there would be no tax due correct, and really they could claim a 10k loss? Also is there any type of agency or other place I could point them for help filing their taxes and accounting for this at EOY besides a typical tax preparation place?
