This is bogus if buyer and seller are independent parties (if the parties are associated then I understand setting true value) as there is usually a reason for the discount purchase (risk items like unpermitted work, crazy low rents in rent controlled area, hoarder, heavy need of rehab, etc).  

But so far I have found it to be an emotionally exhaustive process and have had zero luck.

Motivation is indeed an emotional thing not a logical thing.

But hard for investors to control what they invest and how long can we get the money back so I won't invest more money with them. 

@Douglas Alexander, best advice is to mind your numbers and don't fall in love with a particular piece of real estate.People get emotional over homes...

And it's actually scary that he controls the acquisition and rehab part of the process.

If your property has a history of termite damage, you may be wondering whether an annual pest control service is worth the investment.

They're not investors so the market prices and FED rates control them.

I don't see rates dropping, especially if they can't control inflation, which was supposed to be under control, but appears not.
