I wonder how many new rehabbers know about these unknown risks lurking in the background.

There also many unknowns like the actual inflation rate, an estimate is necessary. 

If you reverse look up the address sometimes the residents names show up.Can’t you just serve the paperwork to “unknown occupants”?

Only way to mitigate the unknown is to assume a rebuild cost.

I still cant figure out how to get a picture off my phone and on to a computer LOL.On the flip side your take down of Clayton Morris saved unknown numbers ( hundreds ) of investors from making probably the worst financial decision of their life.. so for that alone its worth 20k upvotes.. :)

The others are unknown to me.Cheers!

I think the known and unknown tax implications prevent many Canadians from investing south of the border. 

However, HUD will allow for a reduction in the offer if a problem that's unknown now crops up after the offer has been accepted - I know several people (including my mother) that got some money off their HUD deal.

I may be missing something in my question that is a current unknown, but I'm hoping someone will understand what I am asking.

for us it is fear of the unknown it is always scary doing something unknown.
