Population growth, job diversity, and low DOM (days on market) are significant indicators.

On the flip side the clients I fund in my land deals are doing very very well in the foothill subdivision 50 miles or so west of the springs.. but thats the land game buy low sell high.. cant wholesale that stuff it needs to go on MLS to marketed and turn around time is generally 90 to 180 days but nice margins for my clients ..
