If real estate values drop sharply during the course of a trust deed or mortgage investment, it can potentially put the investor’s principal investment at risk. In a worst-case scenario, the property may become worth less than the outstanding loan amount, leaving the investor with a loss.

However, it’s important to note that trust deed investments are typically structured to mitigate some of the risks associated with declining real estate values. One way this is done is through loan-to-value (LTV) ratios, which limit the amount of the loan relative to the value of the property. For example, if the LTV ratio is 65%, the loan amount cannot exceed 65% of the property’s value. This can help to protect the investor’s principal investment and reduce the risk of loss.

Overall, while a sharp drop in real estate values can certainly be a risk to trust deed or mortgages investments, these investments are typically structured to minimize this risk as much as possible.
