Go through all the popular websites but this task is daunting.

My advice is check where the jobs are - aside from the Front Range popular cities. 

There are a lot of neighborhoods here that are transitioning or are becoming considered "more popular" than they were before so its great to be up to date on the local trends.For my first purchase, I am not looking to have to make too many upgrades within the first year, so I look for ones that are turn key and hopefully have renters in them.  

You could probably make it look really nice and all shades of grey are popular right now.

livonia is super popular tonight... lol this is the second thread that talks about my city! 

Probably the most popular in Hawaii, at least within REI circles.

As for Windsor @Matt Geerts and @Samuel Sedore - i would guess similar to any areas, there are Dumps and there are hidden opportunities (Gems), we all like to target the growing, popular areas - as with Stocks, but best time to buy is when the markets are struggling or ready to rebound, not when they are popular.  

I'm looking at homes under 140k in areas that are popular with young professionals and new families/couples.  

It seems to be popular with people relocating to Silicon Valley as well.]Kind regards,Arpad

The most popular is Revit and Autocadd in the commercial market.
