I can just imagine the sharks starting to circle now that they smell the blood of fresh meat in the water. 

When I started Windpouch my previous company that went on shark Tank that was 100% just me and honestly it didn’t go too far.

Considerations I've found so far include: various layers of outdated insulation (mid-80's fiberglass stuff laid over old vermiculite), 1x2's nailed together to create 2x4's (but still relatively sound structure for the age), asbestos siding (needs a powerwashing and I've found it's totally OK, until it's time to rip it off or demoed), 1" galvanized metal water main is very old, electrical wiring that is visible is a hodge podge mess, there's an old gas pump on the site (not sure if tanks are still buried), real bad mold in bathroom, at least 3 layers to the foundation (that looks solid still), ugly old wallpaper, cigarette smoke smell, kitchen is a complete gut and remodel, nearly the whole home is.  

Our builder added another tank and field.Keep in mind that there are pros and cons to a custom build.

@Amy AzizHey Amy I am looking at doing land investing as well and I am pushing for the land shark course?

Seriously though, from a somewhat seasoned investor who has been there and done that, the contents of the UBG should be required reading before any new investor wanders aimlessly into the shark tank.

Our market hit the skids and values went in the tank.

Also, stock market alone could tank and nothing necessarily has to happen to real estate prices.

Originally posted by @Michael Robbins:If the market tanks then at that time I could take on leverage or I could choose to wait it out since I do not have to worry about debt service during times of high vacancy.   

As Kevin O'Leary from Shark Tank says, if your investment is not making any money, it's a hobby.
