You see, ceiling fans are far heavier than a typical ceiling light fixture, and the rotation of the fan also introduces some higher forces on the mounting than a normal ceiling light fixture.

Any place you invest you need to have one of the following be true in my opinion:1) purchase considerably below market value (very challenging in a red hot market)2) force appreciation though increase rents or rehab (easier if you have skills/desire/patience)3) be able/willing to wait for the next cycle (5, 7,10,15, 30 years, think Texas in the late 80s)4) have great positive cash flow that you can weather rent loss or massive reductions in rent to the tune of 30-50%.

Others gravitate to them at the meetings.  

The benefit for me was that I put it all together which forced me to think a lot about my numbers in a way I usually don't.I don't know if if I would recommend others do take my approach with regards to remodel and rehab.
