Investing with borrowed money is a double edged sword. This strategy works as long as property values are increasing and your bank doesn’t “call the loan”. If values decline, using borrowed money, your losses accelerate just as fast.
Keep in mind, this is the same strategy that the famous Dave Ramsey was using when his bank gave him 90 days to come up with $1.2m worth of short term loans, 60 days after that, they demanded another $800k… he filed bankruptcy, eventually he bounced back years and years later.
Morale of the story, you have to fully understand the risks you are taking if you are using leverage and don’t be surprised if “worse case scenario” becomes a real scenario.
