Anyone have a new house built by one of the more generic builders like Pulte and such and have the plan modified with flat threshold doors and similar wheelchair type stuff? Was that a headache or easy process? I'm kicking around the idea of going for a new tract subdivision build, because there are lots more to choose from, but between the unhappy online reviews, questionable warranty specs, and sales agents who just give a canned reply of 'when are you looking to buy' when emailing about a floor plan with room measurements...LOL. What experiences did you guys have with the big builders?
