Is this a real business? I assume so, and only because I can see the houses built or being built.
My wife and I have tried numerous times to set up an appointment with the sales people there. Not through a Real State Agent, directly with Sharbell. Result, numerous mails unanswered, an appointment set up with no follow up or cancellation notice ...nothing. Is this even a legit business? I can only imagine buying a home from them and having any trouble that needs a profesional and quick response.
Good luck to anyone searching or buying here.
