What's the deal with the $60k houses in Chantilly, VA?

[Wade McMaster]

I'm really new here, and I don't know much. I've noticed something that seems strange on Zillow that I was really curious about. There's these houses in Chantilly, VA that are under $60k. If you're not familiar with the area, that's less than 5 years' rent for a modest 1-bedroom apartment in this area. These are 2 or 3 bedroom manufactured houses. I found the HOA fee was listed as $1045/mo. What's up with that? One line in the information says "Ownership: Ground rent." What does all of this stuff mean?
