Computed decision comparison
Vinyl siding vs fiber cement cost
The modeled upfront totals are $15,195 for Vinyl siding and $20,953 for Fiber cement scope proxy, a difference of $5,758.
Both sides use 1,800 sq ft. The fiber-cement side is represented by the existing broader siding baseline used by the legacy comparison and is labeled as that proxy.

Comparison questions
Which option has the lower modeled upfront cost?
Vinyl siding is lower in the current static default by $5,758. This compares model records, not contractor proposals.
Are 10-year and 20-year replacement costs included?
No sourced lifespan field exists in the shared baseline store, so the site does not invent replacement cycles. Those horizon cells remain explicitly not modeled.
Do both options use the same source system?
Yes. Both are computed from the current baseline store and index snapshots. Any proxy, quantity normalization, or retained legacy factor is disclosed beside the option.
