The action would have to be legal in nature, the path of which is unclear and is rooted in how they purchased the property either through standard sale or through an installment contract like contract for deed. 6.

For instance, negative square roots were a purely abstract concept for many decades, until technological applications for them were found.

Always used VERY general terms, "this is nice, this is a good price, this is a decent area"...i mean give me something rooted in research or experience...not something I could get from watching HGTV.5.  

It wouldn't make sense to rebuild & re-use the old outdated sewer hookups, in fact up here 'code' would not allow it on a complete new build.BUT if it is in fact hooked into the old system (& speaking from experience), I would definitely scope the sewer for breaks & tree roots.

I  had damaged lines ( minor cracks) where tree roots get in and severely slow the flow. once a year or every other year I used to rent a 3/4" sewer aurger for 75 bucks and clean the line from the house to the street (about 80 feet).

The key is to root out the deals and then spend the time on a real evaluation. 

Foundations are usually solid unless something was neglected like tree roots, improper drainage grade, etc.

I'd really be open to places that have a lot better rent-to-value ratios, but feel I don't really have the connections or roots to be looking into these areas, nor would I really like to invest time in living there.  

I am rooting for a bidding war.

And he is right, their roots come above the surface.
