For the two in Indiana, my property manager has a crew that does maintenance - and they are the eyes and boots on the ground for the property. 

With limited days left you have some hard decisions to make.You need to fully understand DST'S and TIC's and go in with (eyes wide open) before making a decision like that.

The property is technically a duplex in the county's eyes, so renting both is fine.

it always cracks me up when folks say " the agent did nothing"   you have no clue as to what the agent did or did not do.as agents sometimes we get a laydown.. other times we work 100's of hours on a deal.. they are all uniqueyour self professed fair honest man.. how would you like it if someone was coming in and trying to bump you from a ratified contract.. its only a win win in your eyes  @Wayne Brooks  Wayne makes good point. 

Account Closed I hope you're going in to this with your eyes wide open.

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.

We couldn’t see eye to eye on property value. 

Some counties keep an eye out for entity transfers and will stick you with property tax reassessment. 

I’ve recently been looking into multi family properties in Cincinnati and i came across something that caught my eye.

Don't get me wrong, the flooring went down fairly easy and it looked decent to the untrained eye, but I saw every imperfection and misstep that I made in laying it.
