Roof may need some attention but have not had an inspection-this is just general observation. 

Thanks for sharing your observation. 

I’d be open to paying a delayed down payment in 6-12 months using rent cash flow to pay it.I have a property mgmt company ready to go and could have the 4 BR’s in the main house rented quickly and the separate in-law apt is already rented with a solid tenant paying  $1000/month on a month to month lease.I really need to observe an experienced seller finance / subto REI engage the seller, explain how it’s a win/win/win for everyone and get the contract locked down with lawyer and title company.  

Meanwhile, historically we've observed significantly higher city-average cap rates for short-term, Airbnb rentals.

An example would be smoke and carbon monoxide (co) detectors - in the past we were not asked to note their presence or location, but in the past many years (I can't remember when it started), most lenders added those observations into their assignment conditions.

The physical things mentioned such as the car are things I observe and take note of, but are not my primary decision making points.

Make sure that you get an inspection and observe the reputation of the builder, 

Not a lawyer, not legal advice, just sharing observations and experiences. 

Our observation is that once we turn a listing live on Zillow in the first 12 -24 hours we get a lot of highly motivated people with a very high sense of urgency: they need a place now and often have been turned down before because they did not qualify.

Just an observation, might be better values in Belleville or in Collinsville as @Keith Winkler noted.
