On the other, you are doing all the work, and essentially, the investor gets more return than you since you lose all of the time associated with the property.

Are there any fees associated after they property is sold to the highest bidder?

These are all associated however; have exact definitions.

I would recommend joining the Austin Apartment Association if you haven't already.  

The equity in your property has opportunity cost associated with it.  

Sure, you probably want to start going to REIA's like CCIA or Southside builders association.

You may also find it helpful to attend the local Real Estate Investors Association (REIA) that meets each month.

Then there is also the Price Escalation Addendum to Agreement of Sale (PEA) that the PA Association of Realtors uses - this is used to bump your price along until it reaches your stated maximum.

@Craig Lessler  It looks like you are an agent, why not use the Arizona Association of Realtor forms as a basis?

Tempting as that sounds not worth the many many risks associated with it.
