There are many Real Estate practitioners in US. Just don't be like Everest Realty in Boston. I went to see apartment with them and they treat you with contempt if you don't get the apartment they show you. If you are non Nepali they will be extra nice but if you are Nepali they give 3rd class treatment specially if you don't get the apartment they show you. I heard bad things from people who bought real estate from them too.
