@Cameron Riley I developed a software for myself and use it to manage my properties.

Do I try to go through real estate agents or mortgage brokers or maybe there is some really great targeting marketing techniques? 

well what I would do is tell the seller the house needs 45k.. and since he holds the first you are improving his collateral therefore its safe for him to take a smaller down payment.Maybe offer to escrow the rehab funds so that if you say your going to rehab but don't he can go in and grab his 25k that is not coming to him in the form of down paymentlet him be in control of that 25k in some manner.. that may work.Its just like when I tie up development ground if I have a very cautious seller..

@Nicholas HeinrichLand that can be developed into subdivision;  individual houses; RV Park; mobile home park; storage units; apartments; commercial buildings; strip mall are good deals.  

I keep getting shut down by the big banks when I tell them I want to develop a partnership and explore flexible lending arrangements...

We own several properties here in Lynchburg, and have recently started using the BRRR technique on several of our rentals.

Your ideas will develop as time goes and it will be easier and easier. 

You could potentially save a lot in taxes and develop a nice real estate portfolio (or other assets) in a tax-deferred account.

For example, a lot of people did not know how to rehab but chose to flip and developed rehab skills along the way.
