How do you guys calculate ARV when buying off market deals?

[Ryan Stevenson]

Hey guys, Investor from Canada here. 

Just wondering what is the best way to calculate the ARV on a potential deal when not using an agent or don't have MLS access. I'm not sure if we have public access to any sold properties, we don't have Zillow or Redfin just realtor.ca and other sites that all use the public MLS.

What do you guys do? Ask a favor from an agent? Offer to pay them a bit maybe?
