In  1965 only 10% of homes in the USA had air conditioning, as this number has rapidly grown, people have begun migrating south due to the better climate.  

NOTE:  with the oil base primer, make sure whoever is applying has sufficient ventilation in place--I've seen plenty of painters get 'loopy' from the chemicals without proper air change ventilation.

The common advice seems to be, work at a fix before buying.Bring it to the seller in a tactful/reasonable way and just let them know that it’s a concern and I want to have it further evaluated prior to closing.I am hoping that they do not have a problem with it.Someone suggested threatening to walk and/or notifying bank of our suspicion and the fact that they will not let us inspect.I am trying to avoid any kind of antagonizing approach in the hopes that this can be resolved/mitigated without too much issue.I do like the property and not wanting to walk away, just want to figure out a way to resolve before I take ownership.For now, my summary action plan is to move forward with tactfully notifying the seller of my concern and desire to inspect, complete an inspection, mitigate or come up with a plan to mitigate and then also empower tenants to work with management at addressing mold by reporting any leaks in a timely manner to allow for prompt fix, as well as possibly suggesting they purchase damprid which I hear helps with moisture and making sure to pass on educational/informational material on indoor air quality.There is an indoor air quality guide that someone in a facebook group that I am part of suggested, which I intend to make as part of my lease addendums/guides for tenants.https://www.epa.gov/indoor-air-quality-iaqI do have a contractor lined up to address some regrading issues and also visible cracks which could be where the moisture is coming in through.The challenge is that mold is everywhere and I do not doubt, that we will find something, the key is to work together to “address/mitigate” vs. turning a blind eye which I suspect may have happened here.In the end, I like and appreciate all the comments.I think the comment that sums it up well is @ Clay Hartwig’s comment that the problem is not limited to just the tenants getting sick, the problem is also in working to mitigate moisture which could essentially kill the house.Thanks again to everyone that offered suggestions on what to do here.

I'm not sure about Kansas City, but there a lot of Air BnB's at the Lake of the Ozarks and in Branson. 

That said, I'm seeing as low as 4% for class A product in core CA markets, 5-5.5% for B product in Phoenix, Atlanta, Houston and Central Florida; and 5.5% to 6% for B- to C+ properties in those markets.CBRE puts out a great cap rate study twice per year--you should get a copy if you are looking at multiple markets. 

Croix and I also had a brief talk with someone who has been successful with a one bedroom on Air BnB on St.

My and my sister's bedrooms were up in the attic and our walls looked a lot like what you have there @Ryan Richard The entire place is about 1200 sf and had a 2 ton A/C unit in Orlando, FL and that was fine for cooling even in the summer.The upstairs would get a little warm during the day but that was more due to the air return being down stairs and not having enough return air flow from the bedrooms.

I have had good luck with Blacklick Estates, but deals here are starting to become more costly and not as appealing as they once were due to the demand in housing in central Ohio.  

Under $200K sounds right.Possibly look into another market like the Central Valley. 

Then, somebody that wants to upgrade in the future can easily pull the existing wires out of the conduit, pull thicker wires into the conduit, and install a larger breaker and outlet.The 240 V circuit in the garage may also be interesting for a future tenant that wants to run a welder or a big air compressor in the garage - somebody that likes to work on cars or build things at home.From what I remember in art class, sometimes the kiln runs for several hours.
