I have never thought much of Pulte's work. Yes, they have had shoddy construction in the past. Today? I don't know.
Can't you buy a house that a homeowner is selling instead? Usually by then, all the kinks are worked out. The first homeowner has gone to the mat with the homebuilder to make them address the punch list and fix any problems, especially in the critical first year. If you are looking at a house in a neighborhood where a homebuilder is still building, the houses sold by homeowners are competing against the builder, so they have to price competitvely.
You can't go by just what you see at the builder's show home. When it gets down to it, EVERYTHING you see in those homes is an add-on. Big money add-on too. What you'll get is cheap, cheap, cheap.
I bought 3 new houses in my time. After the third, I decided that I would never buy new home construction again. Too many fights with the homebuilder to get promises honored, sick and tired of no trees in the yard, having to start over with turf that requires so much work (and the homebuilders scrape all of the topsoil off and SELL IT. You're stuck with the dirt underneath that grass hates, and weeds love.) And you have no idea what the neighborhood is going to be like as they fill it up. At least you have an idea with a neighborhood that's more established.
I don't know that his has helped you much. I know it's hard when they give you incentives, but I found after three of these houses (not Pulte - I was smart enough not to buy theirs) that the incentives didn't save me the money that I thought they would when it was all said and done.
Do lots and lots of looking and really educate yourself. Talk to people in the neighborhood who are willing to tell you about their problems, if you really want to buy new construction. At least you'll know what to expect.
