Looking for people who have flipped houses in Alberta!

[Scott Galloway]

I am looking to do a flip in the Edmonton area either near whyte ave west of 99th st or walking distance to West Edmonton Mall.The Lrt will be there before to long and were looking to use Air B N B. I always thought a place would get a lot of traffic if there was a hospital within walking distance.

These are some numbers I came up with. Hoping for someone to help critique them... I have spoke to realtors and continue to I just want as many opinions as i can get.
