The biggest things to keep in mind when finding a brokerage is commission splits, market center shares, training, support, and family.

I was a teller working on getting into commission sales.

Because the broker will normally receive the full 3% commission (as opposed to an agent who must split the 3% commission with the broker), he/she is able to split the 3% commission with the real estate investor. 

After going through lots of time of miscalculation of owner statement and other issues with the property management, I gave 30 days notice to the property management.I requested the entire files of the tenants ( the found the tenants for me and I paid 50% of first month rent as commission).They said that they won't give me the tenants applications to me because California privacy act ( but they will provide the tenant leases).

It’s like a job and it’s hot and you can feel a bit paranoid due to all the commissioned and self commissioned sign Police. 🚓🚓😱 

You are also potentially missing leasing commissions, if you hire someone (including most managers) to lease the property for you.  

I paid $810,000 2 years back, and after paying out closing costs and commissions, I don't stand to make much if I sell for anything below the $899k number I'm at right now.

In the meantime, try to get access to more deals whether it be through your own marketing, networking with realtors to bring you deals(although be careful because they'll tell you anything is a deal to make a commission) or some established wholesalers that can send you off market properties.

Maybe I should be getting the management commission?

My number one best all time creative financing of a property that I ever did was for a purchase of a empty lot two blocks from the ocean in Long Branch, I was reading the local auction list in my city when I noticed a property that at auction two weeks before that opened at a starting bid of $25,000 did not receive one bid, I went to the auction thinking I was going to pick it up for $10,000, I get to the auction at City hall and when the bidding started for this particular property I waited to see who was bidding, a man started it and I waited until nobody bid to start my bidding, well this man really wanted this property and so did I, when we were at $50,000 I started to try and knock him out by bidding in $1,000 increments instead of $100 increments, every time I bid he bid a $100.00 more, this went on until my winning bid of $66,700 and it was now mine, now if you don't know much about city auctions you do not walk around with that kind of money, a 10% deposit is what this auction required and they give (I forget the exact amount of time maybe 30 to 45 days to pay in full) now comes the creative financing part, I take my high credit card limit at the time of $72,000 (I saved all the 0 % introductory rate checks if paid to another credit card balance transfer and pay off another credit card that had a small balance of $1,000 and overpay the bill by $68,000, the overpaid credit card company sends me a over-payment refund check for $68,000 (that is 0% for six months being that it was a balance transfer offer of 0% for six months) I pay in full for the property within the time allowed by the city, (this was in 2003) I refinance another property that I increased it's value with the creative equity work I put in and got a favorable appraisal that allowed me to park the debt into a 30 year mortgage, the empty lot sold in June of 2006 for asking price of $229,000 with a profit of almost $150,000 after commissions, property taxes and maintenance/lawn cutting.
