. $300 a month cash flow is not a bad target but when you are dealing with properties of that caliber, one bad tenant or big repair can wipe out years of cash flow. 

to me I view an inspection contingency as you do it and if something is wrong you present it to the seller and say "hey fix this, reduce the price OR if it was major and really bad just walk away".If no inspection was done, then its unethical but reality is its not worth a seller to sue over it.

A good deal to you could be a bad deal for someone else, and visa versa.

If the tenant is bad they will lie to get them out.

That might not be a bad practice - I don't know if there's a template for that. 

You can do everything right on a flip and just have the timing be bad or just have it sit for no good reason.

So much really bad advice was disseminated on here over the years by this guy.

I’m wondering good idea bad idea?

I have nothing bad to say about them since I haven't worked directly with them and they must be doing something right if they are one of the biggest ones in the area.

My guess is though that as you and I suspect it is the "flovor of the day" as you say and a pretty bad flavor at that.
