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.
- Month 1 is the first modeled month. Start is possession/lease start; free base rent begins then. Annual steps occur each 12-month anniversary of start, including the free-rent period. Enter the actual lease economics.
- Reimbursements are fixed monthly inputs and begin at possession or paid-rent start according to the selected rule. No collection loss is inferred. TI and commissions are cash outflows below NOI.
- Cash requirements are month-end deficits, assuming all receipts are retained. Intramonth payment timing can require more cash. Month-end NOI annualized is a run rate, not proof of stabilization.
- The downside holds the modeling horizon fixed. Costs and rent starts beyond it are identified separately. Acquisition, prior renovation, taxes on income and unscheduled capital work are outside this lease-up schedule.
