* Sales Price
* Whether it will be marketed as a lot or a residence
much marketing you are looking for: different agencies have different relationships with the Trulia, Realtor.com's of the world as well as The Main Line Times
the real estate commission is always negotiated between you and the Broker you decide to hire, no matter what is the kind of property you are selling or renting (home, lot, commercial, etc.).
The outcome of transaction depends very much also on the type of marketing campaign your Broker performs and how extensive it is, the target audience is aimed to, the money invested on it and many other factors.
My suggestion would be to re-view all these factors with the broker before making a hiring decision.
I will be happy to show you my full extensive marketing plan if you are interested in, my office is right in St. Davids, PA .
Please let me know if you need further clarification.
Builders may be logical buyers for your property, but I would not limit your marketing to them. A good multiple listing should attract all potential buyers, including builders or property developers.
