Reseller = Mid $xx to $1xx.
It seems that out of the few registered extensions, the only one developed is the .ca extension.
As an end-user they may be willing to pay $xxx to $1xxx with the right sales pitch.
Names like "Law Firm", and "Accounting Firm" make more sense and would profit much better.
The term "firm" is not commonly used with mortgage companies.
IMHO.
Good Luck
IMO, $500 is a good offer you should accept and more than it's value since its not a common keyword term.
A company like that would definitely love to get their hands on this domain name..
If they knew about and then they would have to change everything (branding, advertising, business cards, website etc etc)
It would cost to much when they may have been using this domain for years
