TI, leasing commissions, and replacement reserves

Lenders hold cash for tenant improvements, leasing commissions, and capital replacements. The rollover schedule, not a published allowance, drives the amount.

A commercial loan on a building with expiring leases is partly a loan against future leasing costs. Tenant improvements are the landlord's cost to build out a new tenant's space. Leasing commissions are what the landlord pays a broker to sign that tenant. Free rent is a third cost: months with no cash even though the lease has 'started.' Lenders who ignore those costs are lending against income that has not yet been reduced by the expense of keeping it. Capital Market Funds arranges the loan. The reserve amount is the lender's number, built from the rollover schedule you provide. This note does not publish a cost per square foot.

Upfront reserves are funded at closing, in cash or by a holdback from proceeds, sized to near-term expirations. Ongoing reserves are deposited each month so the bucket refills as later expirations approach. Some loans do both: a lump sum for the next two or three years of known expirations, and a monthly deposit for the rest of the term. The trigger to release money is usually a signed lease and invoices, not a verbal leasing update. A reserve is still the borrower's money, pledged. It is not extra proceeds and it is not the lender investing in the building.

The rollover schedule is the input

List every suite, the expiration, the square feet, whether an option exists, and whether the tenant is likely to renew on your facts, not on a hope. Mark vacant space as vacant. A lender will often assume vacant space and near-term expirations get re-leased at a cost, and will ask you for the cost assumption rather than inventing one in a blog post. Related-party tenants and month-to-month shops get less credit for renewal. Percentage-rent shops need a sales history before anyone treats the overage as available to pay a future commission. The rent-roll companion is rent rolls and T-12s.

Replacement reserves sit beside TI reserves and should not be blended with them. A roof, a parking lot, and an HVAC plant wear out whether or not a tenant turns. Lenders hold a monthly amount for that capital plan, sometimes released against inspections. Mixing the roof reserve into the leasing reserve makes both buckets lie. Grocery-anchored centers add a further wrinkle: shop rollover can spike if an anchor event triggers co-tenancy, which is co-tenancy, not a reason to publish a reserve formula.

What we will not print

No allowance per foot, no commission percentage held out as a rule, and no statement that every life company or conduit uses the same holdback. Life company and Arizona CMBS loans often include these reserves. The documents of the actual lender control. A bridge loan may escrow interest instead, which is a different reserve, described on the bridge pages rather than here.

Questions

Are tenant-improvement reserves the same as replacement reserves?
No. TI and commission reserves pay for leasing. Replacement reserves pay for capital items such as roofs and pavement. Lenders usually keep the buckets separate.
Is an upfront reserve extra loan proceeds?
No. It is cash held back or deposited so future leasing can be paid. You do not spend it on a use the reserve agreement does not name.
Will you state a TI allowance per square foot?
No. The figure comes from the rollover schedule and the lender's term sheet. A benchmark printed here would be read as a quote.
Does free rent belong in the leasing reserve conversation?
Yes. Months of free rent are a cost of the lease even though they never appear as a check to a contractor. Show them on the schedule.
