I don't have access to his book but I find it hard to believe he bases his model on a 50% cash-on-cash return.

Having umbrella insurance or having an LLC for your property management services is a great business model to protect yourself.

Im trying to plan my business model for the next couple years and debating if I want to aim for flips or buy and holds.

I understand that finding good deals is essential to the flipping business model, but I think there are enough properties even on the MLS that are rehab candidates and priced appropriately that will yield a positive return.Base hits win ball games and I think it is important to not focus all of your attention on finding that home run deal.

The lease option or rent to own model is excellent if you have a property that wouldn't necessarily qualify for a typical mortgage. 

I've been looking in NJ myself and have a decent model setup. 

Seems like it could be a slam dunk for your business model. 

The second is that we are a long way off an automated model actually doing the same job as a high level LO.

This significantly increases the real cost of the property and you'd need to include these costs into your financial model.

@Alex Price First you must recognize that at the level you're discussing, the business models will be using a cashflow range because they are using IRR scenarios and not the simple calculators found on BP.
