Here's a blog I wrote about Canyon Lake that should help you also.
Boy, even if we as agents could give projections, (which we are NOT allowed to do), it would be near impossible.
It boils down to that good 'ole "Crystal Ball" scenario.
If you are looking to "buy" or "sell" in Canyon Lake, the best avenue to take is to contact a local Realtor that could provide you with a list of comp's for the area over the past 3, 6, 9, 12 or more months so you could see where the market was, and where the market "is" today.
With historically low interest rates in effect, you may not want to over-analyze the market and worry about the 6-8 month projection, but start previewing properties so you can see the individual differences in the properties. Canyon Lake is a very unique area with many differences in home layouts & locations. Beautiful view's and a very security tight community. Awesome living!
Best of Luck.
