If it stays level for a while then falls in a steepening decline over 6 months, ok. IMHO, you're jumping the gun on this one. Two equal months of short sales in a slow market at peak season indicate much to nothing. Short sales come from people who feel the heat but haven't felt the fire. Owners had their hopes invested in the spring selling season (which was flat) so they held off hoping. Lets see where the short sales stats go over the next few months, my bet is they'll head upward. Foreclosure rates over the last few months might be interesting to look at as well, those folks didn't have the choice of waiting. I see those climbing.
I'm also interested in sales vs. inventory trends over the last five months. Walton County shows flat sales for the last two months, and the MLS shows massive increases in inventory in the areas I'm watching over the same period. That doesn't spell a bottom to me. Plus we still have the lingering subprimers who aren't out of the picture yet, the alt-a resets starting next year, the economy, steadily increasing rates on 30 year fixed loans, shadow inventory we can't see, the climbing national foreclosure rate, bank failures on the horizon, etc. etc..
All of these factors affect people who buy here. My take is this isn't a local market, we are driven by other markets like Atlanta (dismal), Texas (heading into decline), Alabama (dismal), Southern Florida (cratering), Mississippi (down), Ohio, Indiana, Virginia (all in decline), New Jersey (steep declines just starting), and on and on and on. It aint pretty out there for people interested in property down here that's for sure and my guess is it wont get any better for quite some time.
