Self-storage feasibility, around the ramp-up.

Unit mix, occupancy curve and operating cost ratio as the design unit. With the stabilised yield an institutional buyer actually buys.

What this model does

Self-storage feasibility, end to end.

Decide whether the self-storage site holds up at institutional cap rate. Stabilised occupancy, blended rent and operating cost ratio drive the answer, not GFA.

Calculation flow05 steps
  1. 01

    Scheme

    Site area, GFA, NLA, unit mix and levels captured.

  2. 02

    Cost stack

    Shell $/m², fit-out, security and contingency broken out.

  3. 03

    Stabilised NOI

    Blended rent through occupancy curve, operating cost as a build-up.

  4. 04

    Exit value

    Cap rate applied to stabilised NOI for institutional exit.

  5. 05

    Returns

    Stabilised yield, stabilised occupancy and operating cost ratio returned.

Engine logic

Two engines. Scenarios and cashflow.

The two pieces that separate the self-storage feasibility from a spreadsheet. Scenarios that share one project, and a monthly cashflow wired to every input.

Scenarios01 / 02

Multiple scenarios, one project

Switchable in a click. No copied files.

  1. 01

    Unit mix and rent per mix as scenario levers.

  2. 02

    Ramp-up curve per scenario, with stabilised occupancy target.

  3. 03

    Cap rate sensitivity on one project.

  4. 04

    Each scenario keeps its own operating cost build-up.

Cashflow02 / 02

Monthly cashflow, fully connected

Every input touches the schedule.

  1. 01

    Cashflow runs through construction and ramp-up to stabilised occupancy.

  2. 02

    Blended rent steps up through the occupancy curve.

  3. 03

    Operating cost split by staff, management, outgoings and marketing.

  4. 04

    Exit value applied at the cap rate at stabilisation.

Excel replacement

Where the workbook quietly fails.

Every row is a recurring failure mode of the self-storage feasibility spreadsheet, and how the model handles it once.

Use and verify

What it decides. What to check first.

The decisions the self-storage feasibility is built to support, alongside the things to verify before you trust it on a live deal.

What it decidesUse cases
  1. 01

    Right-size the mix

    Test small, medium and large units against blended rent. See the answer move.

  2. 02

    Model the ramp-up

    Occupancy curve as a real input. Stabilised NOI follows the curve, not a guess.

  3. 03

    Pressure-test the operating ratio

    Staff and management as live inputs. The ratio is honest.

  4. 04

    Size the cap rate

    Cap rate sensitivity in one place.

Pre-flight checklist05 checks

  • Unit mix with per-mix rent and occupancy.

  • Ramp-up curve to stabilised occupancy, not a single number.

  • Operating cost as a build-up, not a flat ratio.

  • Ancillary revenue (insurance, packaging) as its own line.

  • Cap rate sensitivity as a scenario.

Questions

Self-storage feasibility, answered.

How Popurise handles the self-storage feasibility.

Is the self-storage model live today?

Not yet. Popurise is live for residential. Self-storage is on the expansion roadmap.

How is the ramp-up modelled?

As a curve from opening to stabilised occupancy, with vacancy and incentives.

Does it handle ancillary revenue?

Yes. Ancillary (insurance, packaging) sits as a separate revenue input.

Can I split unit mix?

Yes. Small, medium and large units each carry their own rent and occupancy.
