What do these oddities in the parcel lookup system mean?

[Alexander Ball]

Hello BPers,

So today I went out driving for dollars, and after I came back to do some research on the properties I came across a couple things I wasn't able to figure out.

When a house is on the record for "selling" for $1, what does that typically mean?  How can I parse that information?

Secondly, I saw a house that was FSBO, and the number I called seemed to be a private person (it went to VM). However, the parcel look up showed an investment company from the other side of country listed as the first name on the taxes, and the second name on the taxes was more what I expected -- someone's name. What does that mean?

Thanks for your help deciphering this data.
