Sometimes yes, sometimes no.
In certain areas of the country (typically depressed ones--Detroit area, Buffalo area, etc.) it is possible. As for Baltimore, there may be some shells available, but I more often see shells in the $15,000 range.
On the other hand, if you're seeing "listings" provided by RealtyTrac . . . no, those aren't real. Those generally aren't on the market and, if they are, they're not for $10,000. There are a lot of threads regarding the source of RealtyTrac's information and why some people are mislead by it.
If you're looking in the D.C. area--no, those aren't true prices. For awhile, I had the lowest-priced listing on MRIS for Northern Virginia. It was a manufactured home in Chantilly for $13,999. And so I became very aware of what the bottom of the market was.
If you've got questions about any properties in the D.C. Metro area, feel free to send me the address and I'll send you what's listed on MRIS.
Hope that helps.
