As others have said, this agent is probably not used to working with investors. Better to move on and talk to a lot more agents than try to get her to think the way you think regarding a property.
After selling my houses retail I often get approached by the agent representing the buyer. Once they find out what we do, it piques their interest. However, most of the time their idea of a deal and my idea of a deal are very very different. Usually the conversation ends after I tell them what I need. It isn't their fault and there isn't anything wrong with that. You just have to find agents that know our business and most do not. The average agent is out there to sell retail real estate. Many don't even believe me when I tell them what prices we pay for houses.
Work the phones and call 100 agents. Try to get listing agents too, not primarily buyer's agents. The listing agents are out there pounding the pavement drumming up business and they are the ones that will come across deals. Don't try to sound like the next Trump because they will dismiss you. Call them and ask sincere questions then promise to follow up in a month. Make sure you follow up on time a month later to show them you are serious.
All the seminars are back in full force so these agents get a lot of fresh seminar graduates calling them when the guru leaves town. The majority try to sound like a big shot and agents have learned to ignore those folks. It takes time to cultivate the relationships you seek. In the meantime go to the REIA meetings and network.
