I get this from one of our neighbors- a rental if it is run down and has loud trashy tenants and cars on blocks would diminish value and rightly cause neighbors anger-- all our rentals are in well established developments-- I give my card to both side neighbors and ask them to please call us if there is excess noise, traffic, residents,etc-- it creates much good will & I also tell the new renter that we have done this with the neighbors-- it puts renters on notice that you will find out about unmoved lawns, animals, etc. as long as your home looks like a home and not a shabby obvious rental, your neighbors will calm down.

Sure, people can overspend or upgrade too much to realize a return, and we call this superadequacy (a form of functional obsolescence) or as some call it, law of diminishing returns.

But given that we're two full time working parents with kids, it's diminishing returns to take on more work (for others) without significant personal payoff.

You can take an action against all of the parties however;  you will find that there will be diminishing returns after the smoke clears.
