Final answer:
A trustee may only do what is allowed by the terms of the trust agreement, which can include selling the land, foreclosing on property, or holding the land until the trust expires, among other actions.
Step-by-step explanation:
When land is conveyed to a trustee, the trustee may do whatever is permitted under the agreement made when the trust was established. The trustee's actions are bound by the terms of the trust, which include instructions for managing and disposing of the trust property. If the trust agreement permits, the trustee may sell the land for the benefit of the beneficiary. Similarly, if the land is subject to a mortgage that goes into default, the trustee could potentially foreclose on the property. However, the trustee does not have unfettered power to act; they must adhere to the rules of the trust. The option to 'hold the land until trust expires' is also a potential action, but this is only one of many possibilities outlined within the trust's terms.
