Synthetic NOI Inflation

Artificial NOI Inflation: when the numbers look real—but aren’t sustainable

Some properties show strong returns on paper:

• NOI looks solid
• Cap rate looks reasonable
• The deal “works”

But in reality, that NOI isn’t real.
It’s manufactured.

How NOI gets inflated artificially

1. Non-recurring income

• One-time fees
• Temporary concessions that expire after the sale
• Unstable service income

2. Artificially reduced expenses

• Deferred maintenance
• Unrealistic insurance costs
• Self-management shown as “zero cost”
• Missing expenses not included in reports

3. Lease manipulation

• Short-term leases with inflated rents
• Rapid occupancy with weak tenants
• Hidden incentives not reflected in reports

The result

Higher NOI →
Higher valuation →
Higher sale price

Until the buyer takes over…

What happens after closing

Reality resets:

• Maintenance returns
• Insurance adjusts
• Tenants turn over
• One-time income disappears

Example

Property presented with NOI of $120,000.

One year later:

• Expenses normalize
• Tenants rotate
• Temporary income vanishes

Real NOI: $80,000

That’s not a small gap—
that’s a completely different deal.

The real issue

It’s not always that someone lied.

They showed you a moment in time,
not a stable reality.

And what isn’t stable—
can’t be priced correctly.

How to identify it

• Compare T12 vs T3
• Benchmark expenses against similar properties
• Review actual leases, not just the rent roll
• Separate one-time vs recurring income
• Check how long the “good numbers” have existed

The one sentence to remember

NOI is not just a number—it’s a story.

If you buy the number without understanding the story,
you’re buying an illusion.
