Best places for market research…

[Rich Emery]

I’m looking to aggressively grow my portfolio. I’m pretty mobile and able to travel (if necessary) to different markets as needed.  I’m interested in locations / markets that have a lot of upside and are trending towards property values being much higher over the next 3-5 years.  

what are the best resources to dig up data to see trends and where market values are looking to appreciate considerably?  My other properties are cash flowing nicely but I’d like to invest in an area where I can bet on equity going up considerably.  

Looking fir any and all advice!
