With my uneducated look, it doesn't appear to have foundation issues. 

Cracks in the foundation, dangling wires, three layers of roofing material on the roof, broken fixtures, off color carpet areas, spots on the ceilings, soft spots in the walls in the bathroom where water has penetrated, swampy areas in the lawn.

My of my rehabs are in KC (same size) and I barely crack $55K with a full rehab including foundation. 

The current foundation is poured concrete that I might have to remove and make new.

Still not enough.... you need your foundation to be as solid as it can be so when the times get tough, and they will, you will not be shaken. 

It could be a crack in the slab.If it were mine, I'd pull up the laminate and have a look, because you can't let this go on.In the mean time, a wet dry vac would probably handle the water.Or, since it's a corner maybe the water came in where the home meets the foundation, maybe pull off the trim at the edge and have a look inside and outside.Good Luck!

Possibly a little foundation work (it’s on blocks)new water heaterneeds central ac/heat installednew roof (fascia and all components included) new flooring possibly some subfloor replacement exterior siding work(paint some, replace some)some drywall work where there are some small and large holes in the ceiling and walls in a couple of spots. couple windows replaced because of broken glassall new doors (2 exterior 3 interior) new cabinets and counters in kitchennew bathroom sink+vanityThis is in South Mississippi and would be using cheaper materials because it’s in a lower class neighborhood. 

Specifically in regards to physical aspects of the home to look for, I would include the big ticket items that can easily be identified such as: roof, HVAC, windows, siding, foundation (obvious dysfunction), signs of water damage/pests when able etc.  

Roofs, kitchens, foundations, hardscape, bathrooms, etc. are larger items.  

The National Science Foundation did a study in the early `1990s that found 55% of adult Americans could not correctly answer "does the earth go around the sun or the sun around the earth, and how long does it take?".
