From what I've been told, the soil in the region (Kansas City) soaks up water, which is how its getting in crawl space.

Installing carpet with a pad underneath is your best and cheapest solution.

Add in lost rent, soil testing, headaches, tenant complaints and claims and it becomes clear life is short and some headaches are not worth the “potential” profit.

Also, it is best if the soil surrounding the house is slopping away from the foundation to direct any water flow away-1" per foot slope will work.

In North Park specifically, you have a lot of clay, ie expansive soil, and it causes force on Foundations and subsequent movement.

If not, you will have to go to the Embassy because a notary has to witness on US soil for reasons I never fully understood.

I only have two underneath it so far.

We are just starting our DD period and have calls into a variety of experts (surveyor, soil scientist, land planner, geotech, etc.) 

Purchase the property with leaky oil tank.Purchase property with the intent of flipping.The sellers were originally going to rememediate however my attorney suggested we accept $20,000 (cost of remediation) off sale price, use the sellers contractor and close on the home.As it turns out the attorney did not read the Remediation contract very well and Remediation was for only partial cleanup and Contractor not licensed in the state of Connecticut which is a requirement.When we begin the process we informed the attorney we wanted all contaminated soil remediatedNow I’m stuck with a property where Remediation will cost well over $75,000 .There’s also an issue with the Well Water most likely being contaminated.

I think wholesaling larger pieces of land might be tough since builders usually need enough time to assess soils, enviromental, planning with the city, etc to make sure they can achieve the project they want, and that can be hard to do within a tight timeframe.
