Oceanview model conventions
| Assumption | How it enters the model |
|---|---|
| Slope and access upkeep | Added to annual fixed operating costs and grown at operating-cost inflation. Ordinary maintenance remains separate. |
| Rate loss | From the view-change year, otherwise-grown nightly rate × (1 − loss%). The reduction is not compounded repeatedly. |
| Occupancy loss | Subtracts percentage points from baseline occupancy from the event year onward and is floored at zero. |
| View-value loss | Otherwise-appreciated property value × (1 − loss%) from the view-change year. Exit discount and sale costs apply afterward. |
| Descriptive attributes | View breadth, protection status, walking time and an adjusted no-view comparable document the thesis but do not alter price or returns automatically. |
| Net operating cash | NOI − capital renewal − debt service − net uninsured physical-disruption repairs. |
| NPV change from view loss | Current case NPV minus the NPV of the same case with all three view-loss inputs set to zero. |
Timing
View loss has no effect before the selected year or after an already completed exit. A separate physical disruption can reduce nights and add repair costs.
Interpretation
Effects are deterministic and permanent, without an assigned probability. No restoration, compensation, litigation proceeds or insurance recovery is inferred.
Exclusions
Income and capital-gains taxes, detailed seasonal cash flows, refinancing, default and a live comparable-sales feed are not modelled.
