However, assuming your pricing is competitive, make sure that your home is being marketed to those buyers who'd find the no money down or closing costs appealing. Kim's correct that today's typical buyer probably already has some sort of financing commitment. Not that yours might not be more attractive, but it wouldn't be the great selling point you're hoping for.
So: Market to people who'd be interested. That doesn't just mean people who are short on cash. It means people who think they can't buy specifically because they don't have the money for a downpayment or closing costs. You (or your agent) have to go out and find those people. They're not looking on the MLS because they already "know" they can't buy. Most of them are renters, and they plan to continue renting until they can save up enough money. Your job is to find those renters and convert them into buyers. Ask your agent for some suggestions.
And saturate CraigsList; that's a huge potential market for you. Sure, put listings under "Homes for Sale." But also under "Homes for Rent": "Why rent when you can own. No money down. No closing costs. Beautiful 3/2..." etc. And under "Real Estate Services": "Want to buy, but don't have a downpayment? We can help...." And under "Financial Services."
Hope that helps.
