you should definitely write a list of domains that are the subject of your offer. also the age of the domain and your expected price. also, which registrar takes care of them.
in this case, escrow is mandatory due to the long period in which you can claim the domain back.
I also hope that you are not guided by the projected value of the domain assessed by Godaddy or a similar service. that usually has nothing to do with reality
100% agree.
Some people might get mistake and think that worthless domains are "premium" and are worth a lot of money, just because some website calculates it price.
Listing all domain names you are willing to sell is important @BenCodie.
