With budget being the driving force of new construction these days, more than once have I been asked the question "What kind of quality will I get for the budget?"
The answer is quite simple and always the same –
The level of finish is a direct reflection of the budget; the quality is a direct reflection of the builder, regardless of the budget. Your budget will dictate the level or type of finishes your home will have: tile vs. granite, carpet vs. wood, drywall vs. plaster, etc. The quality will be dictated by the builder, his or her selection of subcontractors and protocol for managing the project and materials installation.
Do your homework and qualify your bidders, ask for references, and always ask to view a couple of completed homes with difference levels of finish – the quality should be the same.
