(changed anything newer to older)If the condo is new (less than 5yrs old) I would probably not bother but anything older, I think you should invest the $500-1000 to have them check the usual suspects. They are the experts but make sure you get someone reputable and put this inspection pass in your offer to buy the home. Leave yourself an out in case the inspection fails.
We had an excellent inspector for our condo in Calgary. He did look through a lot of the common areas, and had we a ladder on hand, he would have checked the roof also.The best inspector we had was a condo inspector in Vancouver. He actually physically went up on the roof and inspected it... and that wasn't the only impressive thing he did. I've had inspectors for detached homes that refused to get up on the roof (we told them to pack up and leave...)!
Here's a few things I would check myself and/or get the inspector to also:Thanks for the responses ... so what kind of things an inspector should be looking at when we are purchasing a condo unit?
