Do you typically see that the overall cost (time and money) is more efficient working with a quality wholesaler, or do you find that your return on investment is better for running your own acquisition marketing initiative?

Views are important  but not the be all for quality rentals.

Looking for contractor that is reliable and does good work, that is comfortable with using 'big box store' quality materials and working quickly.

Quality PM's would realize it's a long term relationship.  

I don't want the quality of our lives to be tied to how much we work.

In quality control this is know as a fail/pass test as opposed to a quanititative or qualitative test, which tend to be a lot more complicated and are usually done by engineers and then benchmarked against tolerances.

Use a quality skip tracing company and get phone numbers that way.

An exception would be smaller tenant paying below market rent on A quality dirt where if they went out of business we could release to a large regional or national chain at considerably higher rents and sell at a lower cap rate because of new tenant quality.

Going over the contract and helping them to understand your terms will help you sift through the bad GC's and find a quality professional.
