You need to know what its worth. So, you need to have recent, similar comparable sales.
As a rental, its a great deal, assuming the things others mention are ok (not a war zone, can get tenants, etc.) I'd paint those cabinets. I wouldn't worry about the W/D hookups in the kitchen, unless that's unusual. Pretty common for post war ranches around here.
If comps show this is worth a higher price, you need to bid higher to get it. If comps show other similar properties are selling for $15K, you can bid lower.
The HUD company here publishes the bid results. It takes a couple of weeks before they show up, but you can see what the accepted bids. If its the same there, you can spend some time looking at other bids and get an idea of what it might bring.
If you bid on a HUD and your bid is accepted, your earnest money is committed. At least here, and I think its that way everywhere. Do your inspections before making the bid. Doesn't matter what you find after your bid is accepted, you're not getting the earnest money back.
