Depends on your goals, your strengths and weaknesses, your risk tolerance, 

I've organized one in Yokosuka with mixed results. at times we've had strong participation from a few members, at other times weak participation from several members, but inevitably, it falls apart due to the military community members changing duty stations.

Finally, and this is the hard one for me, practice and improve your weaknesses.

Bing's greatest strength, and its greatest weakness, is the higher-than-average amount of low income housing.

So that tells you that the country flood plain authorities and the Army Corps of Engineers are doing something, continually, to address weak spots.

But later decided to go full on and hire good RE Assistant to handle the things I'm most weak at 

I think that leaders in all industry have become that way because they have found weaknesses in the industries they represent and filled in the gaps.

They both said their umbrella goes up to 4 rental properties (how weak!).

Each has strengths and weaknesses.

Is your rental market weak?
