You’re at risk for amounts borrowed to use in the activity if you’re personally liable for repayment. You’re also at risk if the amounts borrowed are secured by property other than property used in the activity. In this case, the amount considered at risk is the net fair market value of your interest in the pledged property. The net fair market value of property is its fair market value (determined on the date the property is pledged) less any prior (or superior) claims to which it’s subject. However, no property will be taken into account as security if it’s directly or indirectly financed by debt that’s secured by property you contributed to the activity.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
