Commercial Real Estate: Buying a Lease
Commercial real estate is property let to businesses rather than to people, and what an owner is really buying is a contracted income stream secured on a building. Value follows the rent and the reliability of the tenant, so the assessment is closer to credit work than to property work.
How it works
Commercial real estate is property let to businesses rather than to people. Offices, retail units, industrial and warehouse space and mixed-use buildings all sit in the same bracket, separated from the rest of real estate by who signs the lease.
The lease is the asset, not the building. What is being valued is a stream of contracted payments from a business; the bricks are the security behind it, not the thing generating the return.
Terms run for years, which is the main attraction. A commercial lease is normally far longer than the arrangement behind a rental property, so the income is contracted much further ahead than a residential owner ever manages.
And the tenant often pays the costs an owner would. Repairs, insurance and service charges sit with the occupier in many arrangements rather than with the landlord. That varies enormously by lease, and the wording is where the money actually is.
The tenant, not the building
So value follows the income, not the square footage. Valuation here is a discounted cash flow exercise in all but name: the rent, and the yield the market demands of that rent, set the figure between them.
An empty commercial unit can stay empty for years. A specialised or poorly located building has a small pool of possible occupiers, and while it sits empty the owner pays every cost the tenant had been covering.
And you are lending to the tenant’s business, in effect. That makes the work a credit assessment rather than a property one. A long lease from a fragile business is worth less than a short lease from a solid one, and nothing about the building changes that ranking.
In practice
The professional costs are higher at every stage. Agency, survey, legal and management work all scale up on commercial deals, and much of it is payable whether or not the purchase completes.
Transactions are rare and prices are negotiated. There is no continuous quote and no volume print to read; each sale is a private negotiation, so the market price stays an estimate until somebody actually transacts.
The cycle is longer than the residential one. Construction takes years to answer demand and leases hold rents still in the meantime, so the upswing and the correction both arrive slowly and outstay their welcome.
And a rate rise reprices the whole sector at once. Because value is income divided by a required yield, a shift in borrowing costs moves every building at the same moment — nearer to an opening gap than to anything one owner can manage. That correlation across the sector is the part most owners underestimate.
Selling can take a year in a bad market. There is no stop loss on a building: liquidity arrives only when a buyer does, so the exit you planned and the exit you get can be a long way apart.
Every transaction costs far more than 2% of a bar. Round-trip cost on the 576-bar series measured for this site is 0.0098 price units — 2% of a median bar’s range, and 45% of the smallest bar. The commercial equivalent is a stack of fees and taxes rather than a spread, and it is paid twice.
Reading the lease before the building
Five things in a lease decide most of the value, and every one of them can be read before you look at the roof. The remaining term, any break clauses, who pays which costs, how the rent is reviewed, and the financial position of the tenant.
The term and the break clauses set how much of that income is genuinely contracted. A long lease with an early break in it is a short lease wearing a costume, and it should be priced as the shorter of the two rather than the longer.
The cost allocation and the review mechanism decide what actually reaches you. A lease where the occupier carries repairs, insurance and service charges behaves nothing like one where the owner does, and the review clause governs whether the rent moves with anything at all. Read all five before you commission a survey, because four of them cost nothing to check.
What commercial real estate is not
It is not a bigger residential letting. The tenant is a business, the lease is longer, and vacancy runs in years rather than weeks.
It is not passive. Leases end, rents are reviewed and buildings need capital spending, and none of it happens without an owner.
It is not priced by floor area. Two identical units with different tenants are different assets, and the difference is the business behind the rent.
And it is not the only way in. Property funds and real estate investment trusts hold the same buildings with daily liquidity, which exchange-traded fund investing puts within reach of anyone.
When it fails
In a flat market the lease is the whole return. When capital values sit in a trading range, the rent is the only thing paying you — and it depends entirely on one business continuing to trade.
The single-tenant failure is the obvious one. A tenant that stops paying takes the income to zero and hands back every cost it had been covering, in the same month.
Obsolescence is the slower one. A building fitted out for one industry, or sited for a pattern of work that has since changed, can be structurally sound and still unlettable.
Borrowing amplifies both. Commercial property is normally bought with a substantial mortgage, and leverage is not symmetrical: on this site’s series, doubling exposure took the base return of 3.61% to 6.61% while the maximum drawdown went from 3.76% to 7.45%.
At three times exposure the shape is clearer. The return reached 8.93% and the drawdown 11.08% — the loss side roughly tripled while the gain side did not keep pace.
And being under water is the normal condition. Across the same 576 bars, 95% sat below a prior peak and the longest stretch below one ran 73 bars, which is what a holding period feels like from inside it rather than on a summary line.
The answer is risk management done before purchase. You cannot trim a position in a building, so the only sizing decision available is the one made at the start.
The original data
Two videos put “commercial real estate” in a title, at a median of 99,582 views from 2 channels and a
maximum of 186,687. Eighteen name real estate investment trusts, at a median of 92,645. The listed
route into the same buildings is nine times better covered than the direct one, and for almost anyone
it is also the more sensible one, because it removes the concentration and the illiquidity that make
direct ownership hard. Counts are in research/broker-coverage.json, scanned across the 24,971 videos
in research/search-study-corpus.jsonl.
The second figure to carry across is the borrowing one. Commercial property is normally bought with
substantial debt, and research/series-measurements.json, produced by site/measure_series.py, shows
doubling exposure taking the return from 3.61% to 6.61% while the drawdown moved from 3.76% to 7.45% —
the loss side travelling further than the gain. Assess the tenant’s business before you assess the
building, because the income is the thing you are buying.

Real estate is the wider category this sits inside, and the differences come down almost entirely to who signs the lease. Valuation is the mechanism that turns a rent into a price, which is the argument the whole page rests on. And liquidity is what direct ownership gives up in exchange for control.
I spent a long time looking at buildings — the location, the state of the roof, whether the frontage was any good. What I was slow to understand is that none of that pays you; a business paying its rent every month does. Now the first question I ask is what the tenant actually does for a living, and whether it will still be doing it when the lease runs out. The building is the fallback, not the plan.
