Loss-to-lease, vacancy, concessions, bad debt

Gross rent is the opening statement. Collected rent is the evidence.

Loss-to-lease, vacancy, concessions, and bad debt explain why those two numbers do not match. They are four different leaks with different causes, different fixes, and different documents. Underwrite them as one vague “loss factor” and you have covered four holes with one label.

Identify each leak

Leakage	Plain-English meaning	Common trick
Loss-to-lease	In-place rents are below market rents	Treating “market” as already earned
Vacancy	Empty units	Using stabilized vacancy too early
Concessions	Free rent or discounts	Hiding giveaways outside the rent line
Bad debt	Rent billed but not collected	Pretending delinquency is temporary forever

These are not accounting decorations. They are four places where scheduled revenue can fail to become cash. Calling all of them temporary does not make any of them temporary.

The $174,000 walk-down

Assume annual gross potential rent is $1,200,000.

Item	Amount
Gross potential rent	$1,200,000
Less loss-to-lease	-$72,000
Less vacancy	-$60,000
Less concessions	-$18,000
Less bad debt	-$24,000
Collected residential rent before other income	$1,026,000

The difference is $174,000. That is not a rounding error. It can be the distance between comfortable debt coverage and a lender asking why the property missed again.

The math also tells you something management language may not. Loss-to-lease is not vacancy. A concession is not bad debt. If someone uses one explanation for all four, the explanation has not met the facts.

Give every excuse its own file

A sponsor may call loss-to-lease upside, vacancy temporary, concessions strategy, and bad debt cleanup. Any one of those statements may be true. All four still require separate evidence.

Open these exhibits:

• The current rent roll and recent signed leases for loss-to-lease.
• Monthly occupancy history, leasing traffic, and the make-ready schedule for vacancy.
• The concession ledger and effective rent comps for concessions.
• Aged receivables, collections history, and resident-screening records for bad debt.

Useful documents have dull names because their job is to record what happened, not help the pitch recover from it.

Separate what management can actually fix

Bucket	Can management fix it?	Evidence needed
Loss-to-lease	Maybe	Recent signed leases at higher rents
Vacancy	Maybe	Leasing traffic and make-ready schedule
Concessions	Maybe	Market comps without concessions
Bad debt	Sometimes	Collections history and resident screening

Notice all four answers are not “yes.” Management can improve operations. It cannot order the market to accept a rent, make every applicant qualified, or collect every old balance because the model needs a cleaner year one.

If all four losses disappear on the same schedule, ask which exact action fixes each one and which monthly report will prove it. A turnaround without dates, owners, and evidence is an alibi drafted before the incident.

Rebuild the rent that lands

Reconcile effective rent from the rent roll to the T-12. If the model uses a cleaner loss factor than the property has earned, write down what must change, by when, who controls it, and which report will confirm it.

The last line of the exercise is collected residential rent before other income: $1,026,000. That is the number the four optimistic labels were trying to keep off the repair bill.
