You do understand that for $18 to happen again you would need 3 things.
#1 complete negative market sentiment towards mREITs which did actually happen mid last year. The problem with sentiment however is that it is short lived and unpredictable and completely unreliable. If you invest based on sentiment alone then you should quit now and open a pizza parlor.
#2 Almost overnight interest rate increase to about 6%. Recall last year we had an overnight increase from low 3% to 4.5% when the feds finally stated they would start to taper. It was investors that pushed the rate up and now it has fallen back to low 4's despite further fed tapering... meaning that 4% is the real actual market rate. To see it jump to 6% overnight would mean that our economy is so strong and people are buying houses and such so fast that we cannot keep up so we need to slow them down instantly. This isn't happening right now. Real estate is anemic.
#3 Margins must be shrinking at the same time as all of the above. But margins are already weak... they really cannot get much worse. It can happen but right now it does not seem likely.
