Thanks so much to each of you for your input and advice @Russell Gronsky @Ricardo Cortes @Luc Boiron I am shying away from #2 as we moved cross-country less than a year ago and the headaches Russell mentioned do sound exhausting and ultimately inefficient. 

It might be a freshie.If really recent, it may not have circulated through bureau of vital statistics or TX equivalent yet.I really don't consider searching Google as an exhaustive search.

You just never know until you exhaust all your options.  

I was once a broker in Manhattan & more increasingly, condos are becoming more & more like Co-ops & if you know anything about Co-ops, the approval process on these can  be quite exhausting.

He must be exhausted!

Sorry - great data just doesn't exist for non-populous regions - plus I want to help the most people possible with this project.2)  I must have the ability to source this data from credible sources.This means that I can't do things like "landlord friendly metros" - as that would be subjective and require an exhaustive look at state by state legislature.Other than that - what do folks think would be useful to investors? 

It gets exhausting.  

So far though I am loving the free resources here and will not start any paid courses (or buy anything) until I have exhausted all other free resources!  

That's my goal.I ended up at BiggerPockets because I wanted to exhaust my sources of information as my Real Estate agents are either to busy to answer some of my questions or would like me to pay a premium for their consultation so I need to branch out.

Many Ontario homes require power vented units due to the depth of our foundation from ground level, A power vented unit runs  around 995$ for a cheap model, you need a gas technician to install it, codes change every couple years so likely the exhaust vent has to be updated as well.
