I think you vastly underestimate the number of small landlords, as well as smaller local PMCs -- particularly for older duplexes, triples, and tenements -- which will never spend the money. Go to places like Boston, where you will find plenty of apartments where your unit still might only have 60A electric service -- if not 40A (I've seen plenty)! You'll find complexes built of multiple 4-6 unit buildings, built 70+ years ago (if not 100+), with dozens of units like that. We're talking places with natural gas hotbox clothes dryers that were installed 30 years ago! Places still with lead paint. So long as someone is still renting them, they won't do anything.
