Then there are the NEFAR fees, about $500 a year, so factor those costs into your business model too. 

I'm a big believer in your business model and know you're killing it with your flexible CFO business which is bringing a ton of value to small-to-medium sized businesses. 

I am willing to volunteer to help with office work, Marketing,  etc to learn more about this business model. 

@Monisha Nabar One model to consider is the passive investor who brings the money gets all of the net rental cash flow until their initial capital is returned and then the split goes to 50/50 for remaining cash flow and sales proceeds

If your model projects (and worse yet relies on) consistent value increases in order for your numbers to work, you very well may end up with a problem.2: Rents can also fall (gasp!).

You can collect the buyer side commission from the seller of the house, plus an assignment fee from the investor.You may want to discuss this business model with @Roy Cleeves.

Is there other models/ calculators you all like to use to get an idea of what kind of investment you're making?

I'd love to hear more about their business model, what they look for, what mistakes people make when coming to them, etc.

I would like to begin branching out into multi/single family homes this year for buy and hold cashflow model.

You could possibly look at the AirBnB model as well.
