Rent roll and operating assumptions

Build the forecast around the units and their path to stabilization.

The Rent Roll Matrix tracks unit types monthly, including staggered openings and changes in occupancy. Use it to evaluate both existing operations and the proposed value-add plan.

01

Up to 25 unit types

Set the maximum unit count and rent assumptions for each of up to 25 unit types in the rent roll.

02

Staggered start months

Choose when each unit type opens. Capture the timing of phased development, renovations or newly constructed units.

03

Occupancy through stabilization

Define starting occupancy, the monthly occupancy improvement percentage and the long-term stabilized occupancy rate for each unit type.

04

Current, market and pro forma rents

Compare pro forma rent per unit with current rent and market rent. Review percentage variances by unit type and in aggregate.

05

Value-add improvement metrics

Review stabilized annual rental revenue improvement, occupancy improvement and improvement in weighted average monthly rent per unit.

06

Ancillary income schedule

Add income streams using the stream type, average utilization percentage and average monthly price.

Acquisition, development and renovation

Match the funding schedule to the property plan.

Use the model for acquisitions, new construction, acquisition plus renovation, or acquisition plus construction of additional units.

Monthly cost timing

Enter acquisition, development and construction costs by month. The model begins in the first fiscal month of the launch year, while spending can start in any month of that year.

Financing by cost row

Define the financed percentage of each construction or development cost row. The remaining cost is covered by equity investment or available cash flow from operations and other activities.

Optional construction loan

Include a construction loan with interest either accrued or paid, based on the financing structure being modeled.

Refinance, exit and sensitivity

Evaluate the capital events over a holding period of up to 15 years.

Choose the stop month and use the refinance and exit selectors to configure the investment timeline.

Up to two refinance events

Switch each REFI event on or off with a yes/no selector. Set a cap rate for valuation and a loan-to-value (LTV) percentage to determine the modeled cash-out and distribution.

Optional cap-rate exit

Switch the exit on or off and choose the exit month. Exit value uses the defined cap rate against trailing 12-month NOI at that month.

Leverage and exit-cap sensitivity

Review the included IRR sensitivity for leverage usage and exit cap rate to compare changes in the financing and sale assumptions.

Depreciation and exit recapture

The workbook includes depreciation and modeled depreciation recapture logic upon exit.

Joint venture distributions

Choose an IRR hurdle or preferred-return waterfall.

Use the model for a single operator or a syndication with general partner (GP) and limited partner (LP) economics. Joint venture analysis includes two waterfall options.

IRR hurdle waterfall

Model distributions using the IRR hurdle approach and review the monthly and annual waterfall summaries.

Preferred-return waterfall

Use the preferred-return approach and review the corresponding cash flow allocations, waterfall summaries and discounted cash flow analysis.

For a GP catch-up provision, use the model’s cash flows with the separate joint venture distribution template with GP catch-up.

Configurable general partner fee schedule

Account for GP fees across the investment lifecycle.

Configure acquisition, ongoing management, refinance, exit and development-related fees to reflect the joint venture structure.

Financial reports and investment metrics

Review the results for the property and each investment party.

Use the financial statements, investment summaries and visualizations to assess the operating plan, capital structure and returns.

Monthly and annual financial statements

Review the income statement, balance sheet and statement of cash flows in monthly and annual views.

Pro forma and executive reporting

Review monthly and annual pro forma detail, the annual executive summary, value-add opportunity metrics and visualizations of key metrics.

Waterfall summaries and DCF

Review monthly and annual waterfall summaries, with discounted cash flow (DCF) analysis for both waterfall approaches and NPV displayed.

Project, LP and GP returns

See total investment required, total cash returned, equity multiple, IRR, ROI and cash-on-cash return for the project, LP and GP.

DSCR and RevPAR

Review debt service coverage ratio (DSCR) and average revenue per available unit or room (RevPAR) alongside the investment results.

Financial report checks

Use the built-in error checks to compare monthly and annual summaries and financial statements, including whether the reports reconcile to the same final cash flow totals.

How to use the model

Turn the property plan into an underwriting case.

  1. Build the rent roll

    Set unit counts, start months, rents, occupancy improvements and stabilized occupancy for each unit type. Add ancillary income assumptions.

  2. Schedule the acquisition and development

    Enter monthly acquisition, construction and development costs, then define the percentage financed for each cost row and the construction-loan interest treatment.

  3. Configure capital events and JV economics

    Choose the stop month, optional refinance events and exit assumptions. For a joint venture, set GP fees and select the waterfall approach.

  4. Review the property and investor outcomes

    Compare value-add metrics, cash flow, financial statements, project and GP/LP returns, DSCR and IRR sensitivity. Use the report checks to review consistency across summaries.
