Always approach the situation as a problem solver and a solution provider, everyone wins. 

My issue is that the seller likes the idea of deferring his capital gains over a few years and I don't know the best way to approach the scenario.

This place is incredible. 

As someone who may find themselves in a similar position (but with a spouse who can help augment the monthly), I would assume your two best options would be to either flip or take the buy and hold BRRR approach. 

What was your approach?

Incredible book.

My question is, how do you approach a potential private money lender when you don't have much experience to show that you can provide a return on their money?

@Aditya Namjoshi - see notes below.1) The BRRR approach is typically used for your primary residence so living in SoCal and investing out of state isn't possible (I don't want to sound negative).

General expenses should be allocated across all your rentals, but if there may be a more practical approach.

We have spent millions of dollars and a lot of time developing systems, processes, technology uses and an incredible team and there is no reason not to openly share that with others.
