To address parking, one tenant blocking in another in the drive and the late night calls it produces has led me to this policy.   

Get out there around 5pm-6pm and walk around the block, talk to residents if you can and see what they have to say?   

Very well said, Dan.Of course just like any industry there are less competent operators and even downright fraud actors, but the vast majority of experienced operators (especially the ones that have been around the block a few times and survived adverse market cycles) are working with the investor's best interests in mind and strive to produce the best result possible under whatever circumstances they are dealt, even when the going gets tough. 

If the tenant identifies an area of moisture that may be causing growth we immediately address the source of the moisture, replace and damage building material (usually dry wall) and or use mold cleaning solutions/mold blocking primers as required. good luck

Off the top of my head a win we are proud of is bringing back a few blocks on the SouthSide of Chicago. 

Also, is there some prevision I can put in the lease to prevent the tenant from blocking the drive access to the ADU/Boat and from physically messing with my stuff, such as a fee.

Memphis is a block by block city, so be careful to get your comps from very close to the subject property. 

"Maybe" 10 blocks. 

Experience – I want a lender who's been around the block and knows how to navigate challenges.

Build site is a block down from my house, so I'm planning to manage myself.
