Office Buildings Are Selling for 90% Off. What That Actually Asks of a Buyer.

Vantrow · Oct 29, 2026

Quick answer

A 90%-off office building is a buying opportunity only if your true basis — price plus the capital to re-tenant and carry it — pencils against rent from leases you've verified. The discount signals a motivated seller, not a sound deal. The edge in a dislocation is clean, governed diligence, not speed.

Are office fire sales a buying opportunity or a trap?

Both — and the difference is your diligence, not your nerve. When a U.S. office building trades at roughly 90% off its prior price, as The Wall Street Journal reported in its coverage of the office market, the discount is real but so is the reason for it. The deals that work reward buyers whose rent roll, lease-expiration schedule, and tenant-credit picture are clean enough to underwrite the basis honestly.

Glossary (the artifacts this piece turns on)

  • Rent roll — the line-by-line record of every tenant, their space (in RSF, rentable square feet), rent, escalations, and term.
  • Lease-expiration schedule (rollover) — when each lease ends, grouped by year; the single best predictor of near-term vacancy.
  • NOI — net operating income; rent collected minus operating expenses, before debt service.
  • Basis — your all-in cost per square foot after purchase and the capital needed to make the building leasable.
  • TI/LC — tenant improvements and leasing commissions; the cash you spend to sign or renew a tenant.

Why are office buildings selling for 90% off right now?

Three forces stacked. Remote and hybrid work cut occupancy; interest-rate increases since 2022 repriced every leveraged asset; and loans written at low rates came due into a market that won't refinance them. The result is forced sellers — lenders and funds clearing assets at whatever the bid is. The Wall Street Journal has documented individual trades at a fraction of prior value. A 90% discount is a distress price, not a market clearing price.

What it means for a buyer: the headline number tells you the seller is motivated. It tells you nothing about whether the building pencils.

What does a 90% discount actually buy you?

A low basis and a long list of obligations. The discount is on the old capital stack, not on the physical building or the work it still needs. Before you call it cheap, price everything the discount doesn't cover:

  • Capital to re-tenant. TI/LC on office can run high per RSF; vacant floors need money before they pay.
  • Carrying cost. Taxes, insurance, and base building operations run whether or not the building is leased.
  • Deferred maintenance. Distressed owners stop spending first on the things you can't see.
  • Rollover risk. A rent roll that looks occupied today can empty out in 18 months if the lease-expiration schedule is front-loaded.

The right question isn't "how cheap is it?" It's "what's my true basis after I make it leasable, and who's paying rent while I get there?"

How do you underwrite a distressed office deal honestly?

Start from the rent roll and the rollover schedule, not the pitch. Verify each lease rather than trusting the summary: who the tenant is, their credit, the term, the escalations, and any out-clauses. Then build NOI from leases you've actually read, model the TI/LC to backfill vacancy, and stress the exit at a cap rate that reflects a weaker, not a recovered, office market.

A disciplined sequence:

  1. Abstract every lease — term, rent, escalations, options, termination rights.
  2. Build the rollover schedule — group expirations by year; flag the cliffs.
  3. Grade tenant credit — one anchor tenant can carry or sink the basis.
  4. Price the re-tenanting — TI/LC, downtime, and free rent, by suite.
  5. Stress the exit — don't underwrite a recovery you can't name.

The failure mode is underwriting the summary instead of the leases. See our note on reading the rent roll before you read the headline.

Where does bad data sink a distressed deal?

In the lease file. Distressed sellers hand over messy records — missing amendments, stale rent rolls, estoppels that don't match the abstract. Every error compounds in a thin-margin deal. At a 90% basis your cushion feels large, but one misread anchor lease or one unmodeled rollover cliff can erase it. The buyers who win treat lease abstraction as diligence, not data entry.

This is where a drafting system earns its keep — and where it must stop. The desk can read a lease file and propose an abstract fast; a person still verifies every line. That's the point of AI lease abstraction: what it reads right, and where it needs a human.

How can a drafting system help without creating new risk?

It compresses the reading, not the judgment. Vantrow's principle is propose, never commit: software stages the work — a lease abstract, a draft rollover schedule, a tenant-credit summary — and a human approves before any number reaches your model. Everything lands on an audit trail, so when a partner asks where a figure came from, you can point to the lease, not a guess.

What the desk does well on a distressed file:

  • Abstracts leases into a consistent format for review.
  • Assembles the lease-expiration schedule from the abstracts.
  • Flags gaps — missing amendments, mismatched estoppels — for a human to chase.

What it never does: sign the number, send the offer, or decide the deal. Judgment stays with you. More on that line in where AI should stop in a CRE firm.

Who should chase office at these prices — and who shouldn't?

Buyers with capital, a re-tenanting plan, and clean diligence should look hard. Buyers who need the basis to be the whole thesis should pass. Office at a deep discount rewards operators who can hold through vacancy, fund TI/LC, and underwrite from verified leases. It punishes anyone buying the headline and hoping the market comes back. Candor matters here: a cheap building you can't lease is an expensive mistake.

FAQ

Is a 90%-off office building a good deal?

Only if your true basis — purchase price plus the capital to re-tenant and carry it — pencils against rent from leases you've verified. The discount reflects distress, not value. A low basis you can't lease up is not a good deal.

What's the first thing to check on a distressed office deal?

The rent roll and the lease-expiration schedule, verified against the actual lease documents. Occupancy today means little if the leases roll off inside two years or the anchor tenant's credit is weak.

Can AI underwrite a distressed office acquisition?

No. A drafting system can abstract leases and assemble the rollover schedule for review, which saves real time. It should not decide the deal or finalize numbers. Propose, never commit: the system drafts, a person approves, and the trail shows the source.

Why are so many office loans forcing sales now?

Loans written at low rates before 2022 are maturing into a market with higher rates and lower occupancy. Many can't refinance, so lenders and funds clear the assets at the available bid — producing distress prices, not market prices.

What costs does the discount not cover?

Tenant improvements and leasing commissions to backfill vacancy, carrying costs like taxes and insurance, deferred maintenance the prior owner skipped, and downtime while space sits empty. Price all of it before calling the building cheap.
