As you may or may not know, over 98% of Bellevue in general is already built out. The usual 'plats' are rare to find and go at pretty high figures. The Camwest and DR Horton communities are realy the only ones that I know of at the present time, other than single builder spec homes. If your budget allows, there are some 'tear-downs' owned by builders and ready for a custom buyer. At my office, we have many connections to the builders who do just such construction.
If you have not yet found what you want and if 98004 is your only location, you may want to find good quality remodels or re-builds in the neigboring zip codes.
If you need some expert advice from a local lagent, I'm your woman with a back ground both in new construction and interiors.
If the price points in the 'Gold Coast' dont work for you, there are several good quality areas just outside the zip code with some new construction and many remodels.
Feel free to contact me at: firstname.lastname@example.org. I'll be happy to converse with you online and see how I can help you. Yours, Lindy Hisatomi, CRS, Broker.
