It costs too much to build and part of the reason why supply is so low.

Because there is so much that has to be covered in real estate school. 

They are your buyers so they can tell you exactly what their formula is, so you can find deals they wantThe ARV*70%-repairs-fee = wholesale price works great mainly for houses under $250K, for houses above that this formula does not work very well in my experience

Community and collaboration is so important in this business.

Please keep in touch if you pursue wholesaling.The demand is so high, and rent to values are creeping up in many of the areas with great school districts, and thus cash-flow is hard to come by, especially if one wants/needs property management. 

So seller's thinking the market is so hot they can price 5-10% above the last sale, then when it sits, they'll take that price reduction. 

Screening is so important.I'd rather have a property sit vacant for another 30 days than panic and rent to someone I might regret renting to later. 

Your question is so targetted that only an expert in ON, NB and AB markets can answer it, and even then it would only be their own experience.

Even then, OOS REI will come with some significant challenges...Specifically, one of the MANY reasons OOS REI is so difficult (esp. for beginners) is that it requires you to assemble, manage, and incentivize a team of people you'll be completely reliant on from hundreds of miles away (sometimes without even meeting those people face to face).

There is so much you can do that it would be difficult to do it all.When I have thought about investing in a new market, I looked at all the properties available and did drive bys.
