Dear client,
Renting your house to a businessman who wants to use it for educational purposes can be a good opportunity to generate income, but it's important to take some precautions to protect your interests as a landlord.
Firstly, it's a good idea to have a lawyer review the rental agreement before signing it to make sure it's legally sound and includes all necessary clauses to protect your interests. In addition to the clauses you mentioned, you may want to include clauses that address maintenance and repair responsibilities, insurance requirements, and tenant obligations.
Regarding the length of the lease, you could negotiate a shorter initial term with an option to renew. For example, you could consider a two-year lease with the option to renew for an additional four years, subject to renegotiation of the rent and other terms.
Regarding the structural changes, you could consider having the tenant provide detailed plans and specifications of the proposed changes and require them to obtain all necessary permits and approvals before proceeding. You may also want to consider having the tenant agree to restore the property to its original condition at the end of the lease, at their expense.
Alternatively, as you suggested, you could consider a joint venture or partnership arrangement where you have a stake in the educational institution. This could potentially provide you with additional income streams and control over the use of the property, but it also involves additional risks and complexities that should be carefully evaluated.
Ultimately, it's important to carefully consider your options, negotiate the terms of the agreement, and have a comprehensive written agreement in place to protect your interests as a landlord.
