asset allocation play, thinking about adding REIT or fixed-income ETF

[stoxtrader]

The title says most of it. I currently have about 30% of my net worth in real estate, approx40% in equities, very well diversified, and now 30% in cash (earning approx 5% pre-tx risk free). As problems go it's an ok problem to have but I would like to drawdown some. I currently have zero exposure to fixed income other than my high yield savings accts and thought this may be an ok time both marketwise and personal asset allocatin wise to dip my toe in terms of building a fixed income position.

I also think it may be an ok time to start a position in various commercial or other types of REITs. I will certainly be doing some research on my own but I would appreciate suggestions from posters here.

for instance, without doing any work at all, I could buy maybe a 1-2% position in BLV (vanguard, 9bps) or TLT and/or IEF, basically the lehman long-bond ETF with an expense ratio of 15bps. I can probalby do better but maybe not by too much..

for a REIT what about something like VNQ or RWR?

I would assume I don't touch this trade for another 10-30 years on the sellside.
