(a) Subject to this section, an insurer may secure, hold, and convey the following real property:
(1) one building site and office building for the insurer’s accommodation in the transaction of the insurer’s business and for lease;
(2) branch office buildings in this state and elsewhere within the United States in which the insurer is authorized to engage in business as necessary for the insurer’s convenient accommodation in the transaction of the insurer’s business and for lease; and
(3) parking facilities adjacent to or in the vicinity of each office building owned by the insurer as reasonably necessary for the insurer and the building tenants.
(b) An office building described by Subsection (a)(1) may be on ground on which the insurer owns a lease the term of which expires not sooner than the 50th anniversary of the date the insurer acquires the lease. The insurer must own, or be entitled to the use of, all the improvements on the leased ground. The value of the improvements must be at least equal to the value of the ground and at least 20 times the annual average ground rentals payable under the lease. The office building must have an annual average net rental of at least twice the annual ground rental. The insurer must be liable for and shall pay all state and local taxes imposed against the ground and improvements. For purposes of taxation, the ground and improvements are considered to be real property owned by the insurer. The commissioner must approve the acquisition of an office building on leased ground before the insurer makes the investment.

(c) The insurer must use at least 50 percent of the space in each branch office building under Subsection (a)(2) that is available for occupancy for business purposes for the transaction of the insurer’s business and not for lease to others.
(d) An insurer may make an investment under Subsection (a)(2) or (3) only in a municipality that has a population of 15,000 or more.
(e) An insurer may not make an investment under this section if, after making the investment, the insurer’s aggregate investments under this section would exceed 33-1/3 percent of the insurer’s admitted assets as of December 31 preceding the date of the investment, except that an insurer’s aggregate investments under this section may be increased to an amount not to exceed 50 percent of the insurer’s admitted assets if the commissioner approves the investment in advance, and the investment may be further increased if the additional increase is paid for only from surplus funds and is not included as an admitted asset of the insurer.
(f) The value of each investment under this section is subject to the approval of the commissioner. The commissioner may, at the time the investment is made or any time when an examination of the insurer is being made, have an investment under this section appraised by an appraiser appointed or approved by the commissioner. The insurer shall pay the reasonable expense of the appraisal. The expense of the appraisal is considered to be an expense of the examination of the insurer. An insurer may not make any increase in the valuation of real property described by Subsection (a) unless the increase in valuation is approved by the commissioner, subject to the conditions imposed by Subsection (e).
