Wanted to know about owner financing, last year I paid cash for a property ( Pennsylvania), and re-sold it on payments, (I'm the bank). 

We were able to buy low and we sold it high! 

I've seen several posts about how you should get private funding from investors, and although I'm not at that point, it would be interesting to talk to those who have actually done it locally. 

If thats not possible B) Get a private lender again just for the down payment and an LOC for the Rehab.why?

When finding a private lender to help fund a deal on a property, can they screw you over and you lose the investment you tried obtaining???

In the interests of brevity I'll get right down to where I'm at:- I am educating myself, starting to network, have started looking for deals and swapped numbers with some sellers- I have capital - I own a home overseas (through an inheritance) that will get sold - educating myself for this sale was how I stumbled into Rich Dad... woohoo cashflow 101 classic online game mindset changer!!

The main problem I am having is that its difficult to figure out the ARV of the property because the property is in a rough neighborhood and there isn't any duplex that has been sold in the area in the past 6 months. 

Click the "Store" link at the top of the page and buy the BP books on "Finding and Funding Great Deals", Brandon's "Low and No Money Down" book, and the new "Raising Private Capital" book.

I'm considering using fund and grow or searching for private lenders.  

Also, keep in mind, when it comes to commercial, some (depending on the asset type) are sold as NNN leases which require very little maintenance and property management, but offer lower returns.
