Needless to say, I am rather concerned with
the manner this is being treated with.
Am I obligated to pay my rent
More importantly, should I confront my
landlord with this matter?
That's up to you. But I don't see where it will do you any good or make a difference since he hasn't been paying for years.
My lease doesnt run out for another 6 months
but I dont want to suddenly see an evicition
notice on my door & all my rent money go
down the tubes.
That's just plain silly.
For the months that you have already lived there you paid rent. It didn't go "down the tubes". You got what you paid for, a place to live.
Any advice on how I should proceed with this
manner is appreciated.
Chill out and ignore it.
The county isn't going to throw you out. It'll just sell tax liens. Anybody who buys tax liens has to go through a complicated procedure to foreclose on them and usually just collects the interest for years without actually forclosing.
You are very likely safe for the next 6 months and more (if you decide to stay). If you don't want to stay past the end of your lease, there's plenty more places to rent in Phoenix.
