When the first two companies will say that they would hire you if you asked a bit less, and you refuse, and the third company gives you as much as you asked, then you know you are working for a market salary. Until then you are probably too cheap.
Sorry, I am not from USA, so I am unable to give specific numbers. I guess you should ask for 140k now, and be willing to get down to 125k (prepare some excuse, such as “normally I would insist on 140k, but since this is the work I always wanted to have, and [insert all the benefits your interviewer mentioned], I’d say we have a deal”).
