PayPal or Escrow for outbound sales?

I would avoid PayPal as they could try and reverse the payment after they have the domain...

I normally do direct payment if you are trusted well and know in the industry it works well.. but if your not best stick with escrow

Yes, Escrow, If the buyer doesn't want to pay up-front. Only consider trust when the purchaser has a reputation to lose.

As for selling on first offer. I've done it many a time in my 20 years in domains, Particularly if they have offered to send the funds direct and in advance and I consider it a reasonable offer. I can honestly say I've very rarely lost a sale but, likewise I don't try to over capitalize on what I consider a fair market value
