What is the going rate for painting a house? Interior only, house is empty. I was told to charge 75 cents a sq ft? Is this wrong?

There is no going price nationally but you can track regional pricing by asking for 3 bids. The economy is slow, unemployment still high so many folks are now painting, some used to sell stocks and insurance. Searching sites like myremodelingproject.com: The Leading My Remodeling Project Site on the Net will also help, think $ .75 is pretty cheap, who told you this?
