All successful plans are generated this way. 

Then any revenue above what I am asking for monthly rent they will pay me 70% of that revenue while they pay themselves 30%.Has anyone had any experience with doing business with this property management group?

However, since I am NOT an expert in everything I assign a value for how confident I am in each estimate and use that to generate a LOW and HIGH estimate value.

I like multi family because it should generate cash flow as well as appreciation.

Indeed, the FAIR ordinance is anything but fair to non-corporate landlords, seemingly punished for investing in rental houses to generate income as an alternative to stocks and bonds.A handful of opportunists likely could learn to exploit these new rules, preying on otherwise law-abiding landlords to obtain legalized shake-down payments.

If LL uses accrual method, they can book revenue without receiving.  

I want to ensure I’m saving appropriately for a down payment and that the property will generate enough income to cover all related costs.Any insights or recommendations would be greatly appreciated.Thank you!

It does not generate the Balance Sheet.

During this time you are not generating any return from the money invested in the ADU.

K-1 losses, generated through depreciation and cost segregation, can often offset distributions during the hold period, minimizing taxable income.
