All good advice here. having had to walk from several deals when we were buying our first house I quickly learned to question what else they weren't telling us? Especially after blatantly lying (in your case it seems several times) on the property disclosure.
Also, as it is a condo, you should have been given contact info for the condo or strata association. They may have some bylaws or restrictions to what you can put in, and they might know more info about the property then the owners. Also if there are any names and phone numbers listed in the strata minutes, you might want to call several of the other owners and ask about special strata increases etc.
Our building inspection reveled black mold int he attic and a crumbling firewall. The roof had been replaced two years prior and the contractor did a shit job (there was sky visible where they had cut a hole to vent the bathroom exhaust. After multiple phone calls back and forth with the realtor and realtor who managed the strata...getting no where, I called the President of the strata council and she mentioned they were aware of some roofing issues and 6 other units were going to need to be fixed up in the future (this was after they already put a 20,000 fee on tow years ago to pay for the roof and siding repairs)
So...got a phone call eventually from our realtor and said "Good News! it is the strata responsibility, you won't have to pay out of pocket!" which means....you will pay for it, and all the other unit repairs though additional strata fees. We walked, and I am so glad we did.
