Each method has a cost in both time and money.  

Would that method work again?

My interest are house flipping and the BRRRR method.

There is no other way to get correct comps unless you know an agent who knows how to really run comps.

It isn't the metric you can talk about on a national scale, but if you keep buying the same product in the same area it is a very easy quick and dirty method to know how you are doing compared to other buys. 

@Jonathan Greene I'm not sure what you mean by "most will not cash flow as an out-of-country investor" as it might suggest that the cash-flow of a given property has something to do with the nationality or residence of the owner but, in any case, you're absolutely correct that, historically, the net rental yields of LTRs in US cash-flow markets like the Mid-West have been typically higher than in the average European market, although that wouldn't be the case for many other US markets like California or New York.

You can take a deep look at the deals and get an idea of the kind of variety you'll see and come up with your own due diligence method (that meets your unique situation).

Please let me correct your first statement: Sellers "PAY" the buyer agent commission because that is most practical.

Correct me if I'm wrong but VRBO is very clunky and not very host friendly.
