The building is 100 + years old, and has a raised foundation...I'm sure there is moisture down there.  

(termite inspection) moisture reading of 20 %, they recommended a moisture barrier class 1 with a sante fe dehumidifier and liquid termite protection for $4200.Not worried about those cause because I am going to live in this home and have the money for repairs, so i guess my main question is? 

If you have homes with hardie board siding, the moisture and water from them tend to go into the siding if not installed properly.

This could be allowing moisture to drain against the foundation. 

Moisture in the basements are common in the Cleveland area due to a high water table & a housing stock that was mostly built 50-90 years ago.

Look for 10 x 12 or 10 x 14 bedrooms and 8-9' ceilings, good stucco/brick, clean no/low moisture basement, average shingle roof, etc.  

Who can evaluate the source of the moisture?

But for each area repairs and capex are a different amount, for example, I live in great lakes so there is a lot of snow and moisture.

It's a mistake to put carpet in a bathroom, kitchen, dining room, or any space where there is a high risk of moisture and/or food spills.

Debating whether or not I should hire someone to inspect this area and see if there's any standing water or moisture build up (during inspection, there was some moisture build up but I'm planning to fix that by improving the soil grade around the house - so it drains away more effectively)7) Vinyl exterior - periodically pressure wash it every few years?
