Not disregarding wholesalers at all (I truly appreciate them and think they have a place in the market) but I feel yucky simply saying sell me your house for penny's on the dollar which is the primary reason for including the other options listed above.

They are simply a way for the broker to get an indication of your intentions.

A real small per unit return simply is not worth the effort of residential RE. - real wealth is tough from cash flow alone and in markets that have historical appreciation below inflation for this century the return is largely from the cash flow.  

But I have more than once kept deposits from wholesalers that simply tried to tie my property up and then couldn't move it.You are welcome to do any due diligence before you put the property under contract.

I'd simply tell them that when the temperature on the thermostat is changed, it takes time to reach that temp. 

If you were not notified, and they simply stopped.....its time to start digging to make sure something is amiss. 

I'm simply a user of REI Reply.

I would respond by making the observation that it is not simply them "telling [their clients] what they charge."

Either share in profits, but if you simply don't want a second "cook in the kitchen" finding a passive partner may help.  

Entering into a equity partnership is a better strategy than simply giving the money for a 10 to 15% return.
