It's not that hard to find boarded up apartment buildings in LA, at least. Motels were used for homeless housing during Covid, seemed like a good start. They're already housing-of-last resort options for people, and they're already constructed. Don't hold affordable housing to higher standards than low-end-of-the-market homes or apartments, or you're just going to leave the bottom of the market with even fewer options. Let market rate construction be the new construction - which has less red tape around qualifying for incentives and government funding, etc - and shore up the quality and quantity of the bottom end with government action. You'll be adding more units than you are today, which is the most important thing here.
