Certainly good approach for a rental investment. 

@David KrulacGreat  approach.  

slightly off topic . in Hawaii, while on vacation we heard some loud yelling and and what sounded like a lot of domestic violence happening - I went outside and was trying to determine the location of it and soon another guy joined me who had also heard it - we discovered the room it was coming from and both approached to ask if everything was ok - a big muscle bound guy answered the door sweating and breathing heavy - he said everything was ok and that him and his girl were just having a disagreement -when asked if she was OK - he said yes - then the guy that was with me asked she could please come  outside and confirm to us that she was OK - I was a little taken back by his boldness , but was glad he asked - so she came to the door and confirmed she was OK and didn't need any assistance.

I courage you to find local Real Estate Investment Networking Events because that is a more face to face approach that is often the most impressionable.

Please feel free to approach me with your questions and/or opportunities. 

There are better ways to approach this deal. 

The question is, should I approach them as potential buyers if I have properties that I  buy at 70% off Retail?

All stuff you probably already know, Steven, but spelling it out for the benefit of others.The great part of Bigger Pockets is people get to see more than one approach so they can figure out which would work best for them and also learn new ways to look at it.I advise the opposite approach-  I believe in buying the same multi family, renovating it, renting to get the cash flow and sell in a year and a day so instead of paying the 25-28% federal, 7% state and 12% SS (adjusted for self employee deduction) for an approx. 44% tax rate, I pay 15% federal and 7% state with no SS for a 22% capital gains rate. 

However, these are high burnout and high turnover positions where the sales person manages to survive a year 1 out of 10 times ... a very high failure rate for all involved.A more equitable approach works much better.  

Then, approach a more traditional lender about refinancing so you can cash out your private lenders.You'll have to buy it right and analyze the deal to make sure the numbers work.
