The Social Security Administration (SSA) follows a prescribed sequence in developing
            an individual’s living arrangement (LA) basis to ensure we use the correct ISM valuation
            rule, and we do not overlook sources of ISM. Develop the LA basis for only the permanent
            residence.
         
         Following are references pertaining to the 10 categories used in determining the LA
            basis.

                      (For instructions on determining a temporary absence from a permanent residence, see
                        SI 00835.040).
                      
 
 
When an individual alleges two or more LA basis in the same residence (e.g., rental
            liability and sharing), develop, and document the LA basis highest in the sequence
            in SI 00835.001B in this section.
         
         Do not develop the LA basis lower in the sequence, unless the sequentially lower LA is material to the issue of inside
            ISM.
