Because a direct 1219 listing record was not provided, the adjustment work is centered on 1221 as the lead unit. That makes sense because 1221 needs to establish the benchmark sale. The adjustments below use the Central Ohio ranges already specified and stay conservative at roughly $50 per square foot for above-grade area, $5,000 per garage bay, and $5,000 for a meaningful full-bath difference. Quality and product-type adjustments are judgment calls based on design, abatement value, and detached-versus-attached market behavior.
