Stuff like that.....the calculator assumes that cap ex is a percentage over longer periods of time, but wont be accurate if you get slammed with buying a new roof 5 years into owning the place!

Commissions on lower priced houses are often fixed price not a percentage.

You don't have to care if prices rise or fall, you can self-manage, and know that in good times and bad, you will have a relatively stable source of income that might vary by a few percentage points, but probably won't give you any trouble.

The QI/broker combo is not a normal situation (for the reason Dave mentioned).To answer your broker vs RIA question… The major difference is scope of potential services and compensation structure.An RIA is structured to actively manage money, and as such, they get paid a percentage of AUM (assets under management).

LP gets a 8-10% preferred return and the net-of-fee returns are split 50/50 after the fact.2) A simple assignment agreement on a per-deal basis, where the operator provides the loan and then assigns it to the end investor, whereby the operator earns a brokering or servicing fee (the end investor earns the interest rate on the note minus a certain percentage fee, and the operator earns the rest).I'm trying to weight he pros and cons of both, keeping in mind that I value flexibility, discretion in which deals I choose as an operator, and making it super easy for the borrower.

Every property we sell gets listed on the MLS and while the percentage that sell from an MLS lead is very small, they do happen.  

Of course, you should be budgeting for those items now by setting aside a percentage of your NOI ... if both your HVAC and roof need replaced in the same year, you could be looking at $10-15K ... which means you should be setting aside ~$1500 - $1800 /year. 

I have a bunch but should have increased the percentage a bit over the years.
