What do you think of me low-balling these greedy real estate agents?
It might come off as rude. Why do you want to low ball real estate agents?
They try to suck every penny out of my pocket.
You have the right to turn down offers that you don't believe in. So if you think you can get a better deal by low balling the agents then it is okay.
The thought of it makes my blood boil.
If an offer makes you that upset, then you should keep looking until you find one you like. Low balling the agents might be seen as rude though, and they might not want to keep working with you. Just be careful not to offend anyone.
