I think you should try to advertise this domain in Sweden. "Bo" means "live"(as in 'i live in my house') in Swedish and Bo + .net = BoNet wich should be a great name for a realestate site. For instance there is another realestate site in sweden called "HemNet"(HomeNet). Dont know if anyone would like to pay $80k in sweden though. But it sure would make a nice name
