As an investor, you cannot avoid risks. It's already clear on your understanding that as an investor you already have made strategic plans on what to do in case a sudden risk happens. You are not required to solve in many ways, you only need one clear solution that could solve all that matters in your investment like for example high rate of interest that requires additional capital. There is only one clear solution to that and that is to add your capital of course, it's expected that you always set aside an amount intended for a risk like that. Do not apply for a loan, the more risks you will face. Don't charge your investment with chaos, charge it with care and followup.
