If you close on the property and then discover the roof is leaking, the main sewer line is nothing but tree roots, really any major expense, that can easily put a borrower in a position where they do not have enough actual cash to solve the problem, so the property loses value due to deferred maintenance, or the borrower digs themselves into more debt, making it even harder to get another loan to cash me out of the equation at that upper 20% of equity.

Greening the building means greening my pockets...You are painting a very rosy picture of what the future may look like which seems part rooted in your own fantasy and part in leftist political ideology - former probably is just a product of the latter.
