Help with Escrow.com on Flippa Sale...

My flippa auction ended unsuccessfully and went to private sale. But, a person who did bid on it also PM'd me several times to discuss buying with a purchase agreement, presumably to avoid fraud on her part.

I actually thought it was a bit sketchy, because the example aggreement she sent me for review had an "indemnity" clause that essentially said I would hold her harmless if she violated terms of the sale. To that I politely said no, and if she wanted to revise, to contact me. I didn't think I would hear back...

Now, she had come back a week later, making me a decent offer (by PM which is off limits at Flippa) and stating that she is ready to go, but now is also saying she wants to use escrow.com. I told her fine, but to make the offer through Flippa as to comply with their terms.

I figure this is theoretically fine, because escrow.com is a reputable service that is commonly used with Flippa auctions - BUT, I am not sure how to integrate that into my auction listing and the purchase process at flippa.

MORE IMPORTANTLY - I have read that even with escrow.com, there is room for fraud to occur, and I can't afford to mess with this if I am being set up for fraud.

Not sure how to navigate this. A little help would be appreciated.
