If there is a real estate correction, but your property is full and people are paying rent, then you can just ride out the rise in cap rates and wait for better times to sell or refinance.But if there is a recession, and 5% of the people on your property stop paying you because they have lost jobs, and renters start doubling up with friends and family rather than rent apartments because they are out of work, then you may not make your debt service.So you need to be extra careful right now that any property you buy can pass a stress test of a spike in vacancy or economic vacancy.
