Interestingly, different successful models can exist at the same time in the same area under certain circumstances which makes it even more confusing to the novice.

@Scott Lyons  SDIRAs for Real Estate is supposed to be used for passive income which this model fits. 

Obviously we can't predict it completely, but there are indicators...the Yield Curve, the ABI (Architectural Billings Index), Consumer Sentiment, the Federal Reserve Bank of New York's Recession Probability Model.

We recently interviewed Danny Burbol (episode coming soon), a mobile home investor, who buys mobile homes, rehabs them, then sells them using an owner finance model.

LP is 120 - 130k, APV = 150k I am looking to BRRR this with either 5% down (FHA loan) or put all cash offer (100k) and refinance (leave 20- 25% equity and pull out rest).What would be better? 

Your best bet with least risk is investing passively as an LP on a syndication.

Your future self will thank you for it.My buddy @James Orr did a 3 part webinar series where he laid out a financial model for buying (1) 20% down properties, (2) 5% down Nomad™  and (3) 5% down house hack properties.

The best business model is to buy properties when you can double your investment capital, or earn 50% ro 100% on your money every 1 to 2 years. 

Are saying the Mobil home is for sale, by its LP?

Model good behavior and meet everyone with empathy.
