I'm a licensed Real Estate agent and service REOs. We sign up for so many sites and fees to be able to perform REO. $600 is nothing ompared to what we pay out yearly. 1 out of teh 3 platforms costs 700 yearly. Another one is Yearly Certification of 500 PLUS $1 a month for every zip you service.
Boycott if you like, but if you ask me I would chalk it up to a marketing expense and pay the dang thing.
