man all the reits I own are all at 52 week highs...

REIT prices are based off market expectations but their dividends are based off profitability. Market has been expecting a housing rebound since early last year and it's coming to somewhat of a fruition, hence your price action. Housing prices look to be increasing by a mean of around 5% for the next couple years so, depending on the REITs, I would just hold on and collect on the dividends.

You aren't going to get that type of return many other places unless you're sophisticated enough to pick up some EM, short-term European debt, or can find non-agency mortgages that won't rip off your face on bid/ask. If you really want to dollar cost average, that's not a bad idea, but if it was me I'd just hold on. I'm doing so with my portfolio.
