Project files retain scenarios across the nine workbench models and share a private label. BRRRR and condo models can also share purchase, acquisition, construction and soft-cost inputs. Each model retains its own financing, cash and operating assumptions. A saved tool scenario restores its own values.

Method, assumptions and DC source boundaries
These equations are our planning analysis. Agency sources explain legal or supervisory context; they do not validate a property, approve a lender request or supply the fictional rates and prices above. Method version 2026-10-25.1.
- Enter each omitted amount only once. Allowance adjustments are additions beyond the amount already included in the quote. Credits reduce the same installed scope and require evidence.
- Known comparison cost equals normalized installed cost plus stated duration times weekly carry. The risk-funded case additionally spends the entered unresolved-scope reserve and adds the selected extra weeks. A reserve is not represented as a contractor commitment.
- The lowest reconciled price is a cost comparison among scopes you mark reconciled. It does not verify licensing, competence, insurance, contracts, warranties or payment rights, and does not recommend a contractor.
