Property shark and quit claim deeds question

[Cara Smith]

Hi, I'm using Trulia to find prices on what properties sold for and then using Property Shark to see the tax assessment roll to try to find cash buyers as a way of building a buyers list.

First of all I want to say that a realtor did give me access to the MLS but I do not see any way on here to search for sold properties. So I don't know if I just have limited access. And that's why I am using trulia and property shark as well as the town tax assessment website.

So, on property shark I keep finding a lot of properties that have a quit claim deed and then a mortgage on top of that. These are all owner occupied houses. I'm very confused as to why I am finding so many quit claim deeds and why they are being used in this way?

I found one quit claim deed for 80,000 and then under mortgages it said $550,000. Does that mean the deed cost $80,000 plus the 550,000 mortgage?

I would love if someone was willing to look at an example. I just don't understand the story I'm being told by the quit claim deeds.
