Does anyone know what the salary is for a real estate agent, and an investor?

For Realtors: It really depends on the price of the house sold and the commission charged. Realtors work off commission. It's like a "Pie". In a typical transaction, say 6% is charged. It's then split into 2 pieces and the two pieces go to the Brokers involved in the transaction and than depending on your Broker - they take theirs and you get your piece, how much ever that may be.

As for Investors: If you are working on your rehabs yourself, you can choose to pay yourself hourly or not. It's what's best for you. Most Investors who don't work on thier Investments profit off the sale of the home.

Well Real Estate Agents are all commission based, so they determine their income. Some make 20k/year and some make 150k/year. It's all in the connections they have, the quantity of houses they sell, and the quality of them (price). Same with investors, all commission.

Based on sales, which means you lose, the broker gets most of the dough

It is up to you. An agent works on commission, depends on how many referrals you can get, how much advertising you do and the price of the homes you sell. Same for an investor, they determine that. The more they invest the more they will make. THere is no single answer for either of those.

The real estate agents job is commissioned based. He sets his/her own salary by what they sell or don't sell.

Some sell a lot of property and houses and some sell very little or no houses or property.

The investor is self-employed and determine their own salary also. Their salary is based on their investment savvy and how they do their business.
