I have a BS and MS in Engineering and I design Class III medical devices for a living.   

they live in very good neighborhoods , built in pools , or they have a beach house and or a 45 ft sport fisherman for ocean fishing .  

I didn't try using it that way, but the device does allow for that.

so predicting a crash on the peninsula has been great sport now for the last 4 decades.. the biggest crash happened in SF in 89 to 92 prices did crash some then.. but then made new highs by mid to late 90s.. and now with TEch fully entrenched you have a world class city with no peer.. prices are taking a breather ..

We found a device for smoking pot. 

Also enjoy sports, fishing, and flying.I am a recent graduate and work full time as a drone pilot for a utility company (enjoyed your TFR reference), have cash in the bank and no debt.

Tenant erected a 12 x 12 outdoor extendable living accommodation shed in the backyard without any permission installed permanent tiles, ran wiring in the shed for lighting, fans, for electrical devices and also for air conditioning.

I just started using an ultrasonic device repellant device.

I'm getting bombarded by the local sports team for 7 to 8 month rentals.

Flipping can be a very cash intensive sport, and it is easy as a newbie to go over budget.
