A gym chain might want to own this one or a gym enthusiast.
There are no close sales to base the research upon but then, since buyer has made an offer, play along.
I'd have appraised it for low-mid xxx but if you have an end user offer, negotiate and get the best out of the deal.
Research your buyer thoroughly and then negotiate.
If the other party is desperate and/or needs the domain name, and have deep pockets, just negotiate and play along.
