The issue is not the contract, the issue is going to be enforcing the contract, the individual who was selling this could hold this up for years and cost you tens of thousands in legal fees, and then they file bankruptcy and stall it another 5 years.

Then there were some issues with the inspection report that ruined 3 contracts prior to me getting involved.

This is less of an issue here that what you all are describing.  

There are several other issues (undisclosed maintenance markup fees, excessive charges to our account, significant reductions to agreed rent without communication, etc).

I think new builds don't really work from an ROI standpoint, but if you can find properties that have easy ADU conversions then the value might be there.I'm in MA and we just made ADUs legal by right, so I'm looking into the best ways to add value using them.
