They also act like like they are the only potential buyers for properties they look at.

I would push back hard as almost no other retail buyer is going to go for this

I got a car with four wheels and don't mind driving or doing the legwork to help out of state investors analyze a deal :-)Most of what I do is SFR and 2-4 unit residential (as that's where the biggest pool of buyers are).

I have only closed on my personal residence and am finding I don't have the time to make list or represent buyers. 

First, it is not Real Estate agents that might be looking fo a faster, easier close because they represent the interest of either the Buyer or Seller and they are the ones who need to read, understand, and sign docs.  

Personally, I would focus on first-time home buyer markets/price range (under $150k where I am).

Not a strong investment performer, will most likely sell to a first time home buyer. 

Later I was not satisfied with her home searching skills or Negotiation skills...I switched my Agent then the other Agent showed me a good home, we made a offer and also the sellers accepted it.Now somehow the other agent got to know it and saying that I had signed a Buyer Loyalty agreement for 1 year and harassing me to pay 2000$ to her for showing those 5 houses or else she wouldnt end the contract.

I'm a mobile home investor purchasing mobile homes in parks  to resell to qualified buyers on owner finance.

We recently bought a Fannie Mae property and I was compensated 1% commission as the buyer's agent.What is the right thing to do?
