If I wanted you to buy and I thought it would motivate you to do it now by telling you that prices will be going up on the next phase, I’d do that (well, I personally wouldn’t, but not being a salesman, I’m thankfully not put into that position).
Heck, he might even believe what he’s told you or has been told that by the developer he works for. Too bad the market doesn’t appear to be supporting price increases.
I’ve been looking for a year or so myself and I’ve heard about summer incentives that would go away (and didn’t). Heck, early on and in a brand new development, the guy told a bunch of what turned out to be non-buyers that prices would be going up every phase around $8,000 (he was just responding to a question). Turns out, they haven’t sold many to date, and they’ve continued to lower their prices (i.e. more than once). And this is actually 4S Ranch that I’m talking about.
Don’t let a builder’s end-of-year sales drive push you into buying a house you will almost certainly be able to buy for less next year.
