*hint* I would not recommend OC for rental yield unless you want to do things like vacation rental. 

Rehab: Max offer 70% * ARV - repairs (hint $5k is probably wrong)Wholesale: max offer 70% * ARV - repairs (even MORE important to be accurate here because you have to find an investor buyer who will want REAL numbers, not guesses) - your desired profitKeep in mind if It's listed, you'll have to actually purchase the property & resell to wholesale.

Like a vitual "yellow letter" campaign.Also, as an aside - The ads that tout, "cash cows", "amazing cash-flow", or "stunning returns" without giving the slightest hint of financials or other deals really don't do much for me...but I'm probably just not imaginative enough to get it.

I've also read that it's really important to basically hint/tell the appraiser what price you're targeting for the appraisal.

Find a deal "A hint purchase for 50% of ARV" that is what many cash investors look for when choosing a partner.  

As others have pointed out, give him his money back, get the keys back and change the locks (just a hint on this last one).I've had more than my share of folks who contact me with the "must move in now" business. 

The KW CEO treated me well, but gave hints of being overloaded and we didn't connect quite as well personally as the HER manager.

Hint, hint.

As a hint, put them in subfolders before you get disorganized.  

(Hint - If you sell, it's not pretty.)Like you said, it HAS to appreciate for you to win.
