@Robert Grbac I don't think it necessarily matters where your tax strategist is located provided they have a strong background in real estate, in particular, structuring rental property LLC's with holding company (management) LLC and demonstrate that they have the software tools and capability to work remotely. 

Example of owner financed deal: For Demonstration Purposes Only – this is not an offer (numbers to be adjusted if desired)Purchase Price: $350,000Down Payment: $15,000Loan Amount: $335,000Annual Interest Rate: 4%Amortization Period: 360 monthsNumber of Payments: 120 (balloon payment after 10 years, property to be refinanced with conventional financing and remaining balance paid to owner)Monthly Payment $ 1,599.00Balloon Payment $ 263,000.00Total Payments $ 191,921.00Total Interest Paid $ 120,847.00As you can see this situation would provide a true win-win situation for both parties involved.

In alignment with other postings on this thread, they are saying they not taking business and they are scheduled out for 6+ months, but the moment you demonstrate you are serious and you're willing to pay for the estimate and/or the project is more likely, they remember they can squeeze you into their schedule, somehow.

Advocating that this method will somehow save people money is blatantly false, because as demonstrated over and over again, you will pay more.   

For this a wholesaler-licensee must beef-up the contract to a level where it is easy to demonstrate intention in court that he/she made the seller aware that they were not representing the seller and were actually looking to make a HUGE profit on the deal.
