It’s one thing trying to look at data to see general market movements. It’s another thing to look at individual properties that you’d want to buy.
If you’re looking at individual properties, just review the listings, sales histories and drive around. The feel of the local neighborhoods you’ll then gain is more valuable than any set of data that’s available.
If you’re a forecaster looking at data to prove a point or forecast the future, then the available data maybe inadequate.
If you’re looking to buy, I suggest renting a nice house in a neighborhood where you’d want to own. Don’t skimp on lifestyle by going with cheap rent because that’ll cause you to want to buy even more. Keep an eye on the market and drive around. Then look at buying in 4 to 5 years. Don’t even waste your time viewing houses or talking to Realtors now.
