The two I posted about in March ( during the week before the bottom ) are on the TSX : BMO and TD. I like BMO at $60 and TD at $50 got into some trades at or slightly above those levels in March and took profits when they shot up soon after. Traded the range a little since, but willing to commit serious money again if they get much lower. NA was also a very tradeable bank stock which got really cheap at one point $37 a share and went to as high as $60. We also monitor and trade JPM, MS, and I'm considering looking at BAC.
AAAH NO!! Too much rent control. Too much government interference. Tenants hating you big time. Raise the rent, tenants get lawyers and call the newspapers. A new mobile home moves in, the tenants go out and measure the home. If it is off by 2 inches they will complain on it's locations (too much time on their hands)!! Wrong/bad tenants...can't get them out. It's a white elephant (in California)...Not a blessing to have.
I don't know about CA, but when looking at business models, they are near the top when it comes to revenue/sqf for what's basically, aside from sewer/water/streets, undeveloped land. I've never owned one, but I know in the right place with an upscale layout and quality tenants, they are almost as lucrative as quality u-store-it operations. Depending on the municipality, they can be cash-cows.
