I've witnessed investors make their decision on purchasing a property based on it being an area considered to be a rental neighborhood, or a owner occupant's neighborhood.I haven't quite yet grasped what difference does it have on an investor's profit if the home is either of the two options.More than happy to hear other's take on this topic, Thanks.

It does not need to be notarized, but that would be like a witness for both of you.

The defendant and witnesses were all illegal aliens.

I have worked in soup kitchens, and have witnessed a kitchen running out of food with mouths left to feed.

To keep going, I just have to use my wits, use any money that isn't needed for the family expenses and keep my investing plans to myself.

I am certified by the State of California to testify as an expert witness on matters of real estate valuations including cap rates. 

We have been witness to one of the biggest real estate booms in the history of the US over the past 7 years, and many investors have forgotten the fear of leverage. 

Take a female witness with you, especially since you are a man and one roommate is already claiming improprieties.   

Witness accounts mention explosions from the back porch.

I don't have a kid so my perspective is probably far different than yours but I have lived through this scenario as the son and witnessed other kids my age in the same situation.
