How do you normalize commercial lease proposals?

How do you normalize commercial lease proposals?

Convert every offer to one unit: all-in cash, same dates, same extras. Then compare. Face rent can wait.

This page belongs to a validation / pilot concept. It is not generally available.

Questions this page also answers

What unit should you use?

All-in cash on one calendar, then today's dollars. Not face rent alone.

Do start dates matter?

Yes. Empty months are not free unless the deal says they are.

Do you need NPV to normalize?

You need the stack first. NPV comes after the stacks match.

What if extras are estimates?

Mark them as estimates and test a high and a low.

Plain-language definition

Normalize means make two unlike offers talk in the same unit.

A gross rent and a net rent are not yet the same unit.

A five-year term and a ten-year term are not the same product.

Free months and build-out checks change when cash moves.

Until those sit on one timeline, you are comparing stickers.

This page sits under Lease comparison.

Most failed compares mix gross and net stickers.

Time the credits before you average anything.

Different terms are different products.

After the stacks match, run the NPV walk.

Investopedia defines net present value as later cash brought back to today. That idea is the spine of this page. See Investopedia on NPV.

Editorial commercial interior used as section context. Not a customer photo.

Why it matters

Landlords quote rent in different wrappers.

Teams pick the low sticker and learn the extras later.

Finance wants one stack they can audit.

A clean stack also shows the next ask in a negotiation.

How it works

Write the cash list first. Then decide what the page is measuring.

  • Write the lease type: gross, modified, or net.
  • Add extras the tenant still pays.
  • Place free rent and TI in the real months.
  • Align start dates or name the gap.
  • Then discount both stacks at one rate.
Later cash boxes sit farther right and look smaller than year-one cash.
Later cash is smaller in today's dollars. This is a teaching picture, not a live model.

Formula in words. Normalized year cash = rent + tenant extras − credits, on one shared calendar.

Assumptions

  • Both options use the same start month in this teaching sample.

Edge cases

If starts differ, do not pretend the empty months are free.

Common mistakes

  • Comparing stickers across lease types.
  • Ignoring load factor.
  • Forgetting a commencement gap.

Decision implications

If you cannot normalize, do not rank. Ask for the missing extra first.

Compare this to related metrics

See gross versus net for the most common unit error.

See total occupancy cost for the stack itself.

Limits

  • Normalization does not score the block or the landlord.

When this should not drive the choice

  • Do not force a rank on incomplete LOIs.
