Asking Seller for Repair Credits

[Calvin Ly]

Do you guys typically ask for credit for repairs that need to be made on a property you are trying to purchase? If yes, how bad does the particular repair need to be (in dollars)? Or do you guys use it as a tool to get the overall purchase price down.  To date I have not asked the seller to give me credits for any repairs because they know I am a investor who is going to overhaul the property anyways. Am I short changing myself by doing this?
