The Property Management website lists it as "approximate location: Street Name on contract."

First, there are small grammatical issues with their website that could indicate it might have been built by someone whose native language isn't English. 

The book is already available on the website but I did not know that at the time! 

Are there any tools, websites, or resources you’d recommend specifically for real estate investors in Ontario?

I'm not sure if we can like to articles on our own websites here, so to be safe I'll just suggest the IRS web page, which does do a pretty good job of explaining the basics: https://www.irs.gov/taxtopics/tc510The main thing to know if you're going to claim business miles is that you do need to keep a log of every business trip. 

You can look those up online through the Secretary of State website most times.Hope that helps!

@Matthew McCarty At the beginning of my investing career, I was constantly looking at websites like Zillow and Redfin to see what houses are selling for so that I have a good feeling on the market I picked.

Do you have a website? 

But it's right on their website its now voluntary.

What websites do you suggest to get good information?
