Long story short: I would have paid double. If you read anything else, read the final sentence at bottom.
Needed a home inspector, read about Paul Wilson in Ottawa Citizen and other reputable reporting, was not disappointed. The first house we saw with Paul, which looked new with excellent finishes, he found a buried oil tank, asbestos, cold air pockets in the walls that led to water damage, faulty wiring, bad plumbing, and a host of other problems. As first time home buyers, when he looked at me and told me straight to my face, this home is a massive, then of thousands of dollars money pit, I knew that his experience and knowledge was worth every penny, and that 560$ (including HST mind you) was the best money I ever spent.
He also detected a scent of mustiness, which led him to mold buildup in behind walls. All of this in a new looking house that, to any buyer, would have appeared flawless. If you don't choose Paul, you're throwing your money away. We relied on Paul's extensive experience to make an informed decision, and we ended up with a different home, which he went through and said it was a cakewalk compared to the first. As new homebuyers, you want this man to see what skeletons are lurking in any potential purchase. If we go to sell down the line, hopefully this man is still in the business!
TLDR; on very short notice, Paul was able to put us in touch with a master electrician, who came in and gave the sellers a quote to bring their electrical up to par. This extra support on very short notice, under a tight deadline, made all the difference. Money excellently spent as we will be able to sleep at night in our new home without worrying.
