I do have some that have performed well with long time tenants, but most are fairly transient and after a while struggle to pay so I end up with evictions on occasion.

But, that said, I have been accused of being overly cautious on occasion.  

I've also heard George Mason does them, but when I reached out on two occasions, they didn't return my calls. 

In the time I've spent listening to the BP podcast and reading real estate books, I believe I have heard on several occasions that it is not a good idea to try to time the market.What is the overall opinion on this?

If you have an attorney that you work with on occasion I would contact him or her and just run it by them. 

On rare occasions when my attorney is not around I use the template that we have.

I've had success in personally going this route on a few occasions.

Based on experience being in various tax assessment discovery failures by title companies, I have been able to exercise my title insurance on several occasions and has worked well, not instant but it worked.

Haven't yet had much occasion to learn whether my ARV estimates tend to be accurate beyond proof that my rehabbed units pull market-rate rents, but that method certainly would make more sense. 

I have seen/heard of on several occasions where a bank-owned property had a time period where they would only consider an owner-occupant's bid.
