Reit is extremely not popular here, nor people aware of it. It is a boring stock to watch as compared to ordinary stock, so with little popularity, liquidity is low. When liquidity is low, you won't see much buying and selling activities.
Somemore most invested in reit is looking for like fixed income and long term yield which they won't bother to buy and sell in the market.

In actual fact, selling is much easier than buying, if you sell at discount a few cents, you will see lot buyers coming out. No trade, doesn't mean no buyer. In fact the low volume trade is more down to no seller.

Whenever you see spike in volume in reit, a lot of time, it is because sellers coming out.

REITs get less attention meaning still cheap sales, I don't think we can get reasonable price if the volumn is high and popular. Grab while nobody wants it. There are only a few REITs counter here, study them individually and you will find out the candy in your eyes.
