Is it actually in the city of KCMO, or in one of its many suburbs such as Independence, Lee’s Summit, etc.? Or an unincorporated area in Jackson Co.? Where it is will dictate the rules of that area. For example, you should (have before buying) talk to the city/town/county planning and zoning department to see if it’s zoned properly or is a grandfathered “nonconforming use.” Meanwhile, you can search the city code for “mobile home” and “manufactured home” to see if there are codes specific to it. In addition, the state has landlord/tenant statutes, which may be unique for MHPs. For park-owned homes, the standard Landlord/Tenant law certainly applies, as does any local housing rental codes.
For those other than the poster: Learn from his/her lesson…this is all stuff you should check BEFORE you close, in your due diligence period.
