I looked at namebio for Real Estate domains with .net extension.
There are several sales in mid xxxx. However, the sales are not recent and mainly the domains that have sold have City+Real Estate instead of Real Estate+ City.
However, RealEstateCalifornia.net is pretty good and I would be looking at low xxxx.
RealEstatesFlorida.com is a typo with an extra 'S'. There doesn't seem to be any reported sale with an extra S on namebio.
Not very valuable in my opinion. Maybe someone else could appraise this one better.
