I pick these areas because your BRRR strategy is dependent on finding enough sold comparables upon the completion of your renovation, to support refinancing the property.  

The buyer's bank will assign an appraiser and you will have to go through the nonsense anyhow.Short answer is that you need to make your listing price based on comparable sales, which should de-risk to a large extent the appraisal process.  

 (3) If done carefully, single family homes and multi-family units CAN be adequately compared side-by-side for return potential

@Shawn Holsapple@David FaulknerAccount ClosedThanks for the suggestions and from all the above good suggestions i found that I have looking at the deals like I got on the rentals and comparing the ROI as the same and I have been conservative and now I will try to raise my purchase price a little bit.once again thanks for your good suggestions.

Lots of good info can be found lower on the Redfin listing page with comparable available and sold properties.I'm in Snohomish county and there are REI deals here outside the cities - I avoid the city of Everett like the plague that it still is. 

For commercial what type of net worth qualifications do you look for compared to monthly rent and what sites do you use for criminal and credit checks?

Building costs are high compared to the returns available in the "Disney"/Orlando market and existing properties come with all the issues listed by @Daniel Karbownik (all of which are only increased by the oversaturation of these types of properties in the area).

Perhaps market values had gone down and they found a comparable (or the same) property at a lower price.

One thing I'll add is to make sure to compare apples to apples when it comes to rental demand.

They can have a bit more flexibility compared to the large nation wide banks/lenders.
