Apartment valuation is calculated on operations not on the market
Apartment valuation in my area spiked until the ROI crossed 10+ years. People stopped buying apartment buildings for a while except as owner-occupied with renters to assist. But in my area, none of those reach anywhere near a net-zero mortgage. The market absolutely still has an effect on valuation in most areas.
But two towns over, people are selling apartment buildings with 2-3 year ROIs, and they’re being swept up by one of a small handful of investors. Building maintenance is terrible, and there’s very little interest in the legal risk of being slumlords except those who are already slumlords over 40-50 buildings or more.
