Stanley's daughter came out with a new book this month updating the research -- I haven't read it yet.Stanley identified several factors that keep you rich or poor: where you live, how much you spend on the house you line in, how much you spend on luxuries, how much debt you pay interest on, but I believe his most important finding is that a much higher percentage of millionaire men than normal will report on a survey that their spouse is more frugal than they are.Getting rich turns out to be very much a team sport, specifically, a team of two.

What is the net operating percentage? 

Martin,First on a private adjuster, remember most of them charge a percentage of the claim so unless they get you more than you would have on your own, you will net less. 

None of the CFPB-required disclosures require lenders to disclose what percentage of loans they actually close, and what percent they deny 3 days before scheduled closing after all contingencies have been lifted.

In order for it to be a good buy you want total rent for both to cover the mortgage PLUS vacancy (8%), CapX (10%), repairs (5%), and management fees (10%) (all percentages are just general, you can tweak as needed). 

The percentages you mentioned are a good starting point to concern.

If they are marketing and bringing you new properties, then a percentage or a flat finder fee for each property may be appropriate.If their role is purely administrative and they are simply managing the rentals once they are received, then I would only consider a periodic bonus based on the increased workload.

Should it be a percentage?

And what amortization and percentages are you using for Mortgage amount?

No modification is needed to the operating agreement and as long as you are calling for capital pro-rata from the investors their ownership percentages stay the same relative to one another.Having explained all that, if it were me I wouldn't do it.
