This was caused by deferred maintenance and the tenants' diet.  

I have only run it on propane with the theory I don't have to worry about old gas clogging the carb while it sits.

Due to my car being on the driveway, the tenant steps on the wet grass, and proceeds to slip and fall landing on his bum.Little backstory, they use  a side entrance to get to their upstairs apartment. 

Like alot of things in life it easy to make excuses why you shouldn't do something or should wait to start something until later (investing, dieting, exercising).  

They waste their money they would have been better off saving for a deal because they want the real estate equivalent of a diet pill.

Let the car be your motivation.

However, with proper diet and training!  

I'll answer all the questions I can for a diet soda.

Diets, running that marathon, household projects, etc.But then we look at those people who are successful.

Indirectly: Good diet, plenty of sleep and excercise.
