S.C. Code § 51-15-150
For any or all of the purposes mentioned in this article, any such municipality, upon the recommendation of its park and recreation board, may purchase on time or partly for cash with balance on time or deferred payments, or otherwise acquire any real property or interest in real property within or without the limits of such municipality, securing the notes, claims for deferred payments and interest thereon, with mortgages or deed of trust on the land purchased, or with or by means of an instrument in writing retaining title thereto in the vendor, or enter into any other contractual arrangement whereby provision is made that such notes, claims, or other instruments for deferred payments and interest thereon, and all lawful charges, shall not be a charge against the general credit of such municipality or be a general liability thereof, but that the liability shall only extend to and be a charge against the land so purchased or acquired. Such method of acquisition provided for in this section shall not be considered or deemed exclusive but cumulative and in addition to all other methods of acquisition of lands or interest therein for public purposes heretofore, hereafter, or by other provisions in this article provided.
