I feel there is some value (like mid XXX), but there are lot of alternatives to the name, so that makes probability of resale lower. You can have names like:
bestescrow.com
goodescrow.com
fastescrow.com
superescrow.com
onlineescrow.com
etc etc
so this is the competition to your name (not speaking about new gTLDs names, where domais like flatescrow.zone, flatescrow.space or flatescrow.online, flatescrow.site are possible..)
