re: Buy a house rite now or wait a bit longer?

I had purchased a lot a couple years back with the intention of building last year. Now it feels like I need a PHD in order to time the market right when I have to consider our current home sales price, mortgage rates, construction materials, appraisal values, etc.

I'm ready to get out of my current home so I'm just thinking about biting the bullet if I can get a halfway decent construction bid. Appraisals seem to have caught up at least and hopefully I can sell my house higher than I had initially anticipated.
