Sounds like the voice of experience.  ;-)

Or,would it be effective to send it to the deceased address hoping that it would get to person in charge?

In order for there to be conflict you are insinuating there is a negative effect to the Association or other owners from the board members actions.

The side effect of that is they will repossess from time to time and own property.Again, I'm not up to speed on all the ins and outs, but I do seem to recall there are time limits for certain things.  

Would door knocking be effective?

Some folks I know find them effective; others, not so much.

This is not to blame that the tenant caused a situation for condensation but it is for not reporting issue in a timely fashion which could have allowed fixing and minimizing the effect.

Strategically I would try for locations very close to new development so you get the full effect of their coat tails.

The property is in the city of Nashua, NH where you're not allowed to park on the streets and most properties effectively have no lawn.  

I know that there are many things that can effect this.
