Maybe the Landlord attempted renting on their own and may have oversold the property features and maintenance. 

They do not even write me up for the legit issue because they attempted the extortion and know they can get in trouble.

If the tenant attempts to contact you about this, forward it to the insurance company or their attorney.

So I hired a plumber and he attempted to repair it with boiler sealer but it only made it worse as the boiler started to leak heavily.We have decided to replace the whole boiler and was told may take 1 to 3 weeks as all the boiler are sold out.

Economists on both sides of the coin agree that rent control is not the way to go....Since I can't draw a supply/demand sketch on bigger pockets, I might be able to attempt to explain the general principle behind it.Rent control is an artificial price ceiling set by regulatory bodies (government). 

While I can attempt to lay down the law with this contractor, both the plumber and electrician are also hard at work so I can make sure they are being paid when they want to be paid, every week, or at the end of the job.

If an attempt to find a surviving relative is unsuccessful, the probate estate will escheat to the State of California.
