Was the water table coming up through the slab?

there was and still is a mentality in Detroit going on that residents were not paying their water bills for whatever reason and then the case was made that water should be free.  

They have been waiting 40 years still no bridge.Public water and sewer are big issues. 

Some businesses require the use of a lot of water.

I feel that this neighborhood is on the cusp of gentrification and will derive a lot of benefits from both the cities ten year plan to redevelop the downtown water front and the new high speed walk on ferry to downtown Vancouver that is starting operation in march of next year.  

It could be several different things, including the boiler not being properly vented.Are we talking steam, hot water boiler?

@Jesse Waters thanks a lot!

-Added a closet to the Mother-in-Law bedroom-Replaced the water heaterNow, I realize these items won't add tens of thousands of dollars to the value but am thinking of listing the house for $184,900 which is near the higher end of the market for this neighborhood; I think I could list it for $189,900 and still draw interest but I'd like to sell ASAP.

So here is a watered down summary of my plan, let me know if this is a viable idea.

Some HOA's cover property insurance, water, electricity, cable, etc.
