Unfortunately if you track daily price fluctuations you indeed will go bonkers. Think of it this way, if you are making the decision to save then it is a long term committment not a fling right? You will be tempted by the lures of Sunset Cove and other similar properties. Also there is not any gaurantee at all that Sunset Cove will be cheaper 2 years from now then it is today. The strategy is, you will have close to 20k extra saved up in those 2 years at the 800/month clip. So… how much will that help you? Well if interest rates don’t go up to much, and or the prices of Sunset don’t go up then you will have done okay right? At least you will have a little extra money. Now if the sky falls in the next 2 years like many hear believe/hope it will, then that extra 20k will indeed go a bit further.
My point is that it is frustrating but in the end, you will most likely be glad you waited.
