Unresponsive landlord - any advice?

[Jack Zuchars]

I understand this forum is mostly for landlords but I'm a tenant stuck with a not-so-nice landlord. He wouldn't respond to my emails/phone calls for basic repairs (eg leaking toilet). He only shows up to collect rent. Would say he'd fix things but then disappears without trace until next month :(

What are my options? I was thinking of getting the repairs done myself and deducting it from the rent. What are the pros and cons of doing that?

If not that, what else can I do? I can't wait for the lease to get over but have eight months left on it unfortunately. Please advise if you can. thanks
