I specialize in new homes, and just recently sold homes in two different communities in Cypress. Check out Meritage Homes in Cypress Park (ask for Terence), and Centex Homes in Cypress Landing (ask for Rich). Both communities offer 100% financing with the USDA guaranteed loan program! Check it out!
Hope this helps...
