The only way I'd do it is with a broad Index Fund of either the S&P500 or the entire US market.

Nevertheless, the Case Schiller is a lagging index, so why use it to try and time the market?

@Ned Carey Yep. 6 months later OP would likely have more analytics data than he would know what to do with, sitelinks on search engine results, and would certainly not have been waiting patiently for engines to crawl and index his site. 

If only I could sell tax-free or exchange into a REIT or index fund.

An index  + a spread would be a better comparison and cash doesn't come off quite so badly in many scenarios.But thats neither here nor there, just wanted to get some nuance of my chest and in there for @Brent Davis .

The other is Case Shiller index top 20 largest metros (home appreciation) for past 30 years of historical actuals.Notice anything?

If she wants to invest, I recommend an S&P 500 index fund through any online site such as Ameritrade.

And if I live to the point that I don't want to deal with real estate anymore, I can liquidate everything and buy index funds.

A 10k investment in a normal index fund will only produce 2k in a bull market.

. :0Now, besides RE, all my money in the market is in "Index Funds".
