First off, when you submit an offer, you are required to put in a deposit, typically at least $500. If you have 100 - 1,000 low ball offers in, you sure have alot of liquid assets.
Next, if you just got a job and are living at home with your parents, do you have good enough credit to qualify for a home loan? This is something to give consideration to.
And finally, no agent is desperate enough to work with someone like you. We all have phones and know people in other offices. Word spreads fast when there are potential sponges of time and resources lurking about. And for the suggestion that you work with the listing agent, that is risky, they are there to represent their client, the seller - not you.
What you are suggesting is probably more suited to the FSBO market. You have a better shot of getting an accepted offer from a seller there.
