This is because of less vacancy/turnover, rents increased much faster, less tenant damage, less maintenance and repair costs, and most important of all MUCH higher appreciation due to being in more desirable areas that actually improved instead of staying stagnant like many S8 areas.

It turned out that the tenants did not ventilate the apartment while they did their living/business.

It's typical practice to look at out-of-state (OOS) marketplaces in order to improve cash flow, particularly in high-cost cities like New York.

Look for the up and coming areas where the city is improving sidewalks new development etc.

I also funded renovation of both throughout this transaction and significantly improved the property/raised the rent to market.

.$20k-$50k is a good amount to fund 2-3x improvements for people looking to sell with clear improvement scopes of work with trustworthy contractors on 2nds up to 60% LTV.These are harder to find, especially with fewer people selling, but I suppose a network of agents,  title cos and lenders would help source opportunities in this space.
