How much cash do I need on hand while I wait for the landlord's TI fund to reimburse my buildout costs in 2027?

Options compared: turnkey, allowance, and as-is

Before you can size the cash requirement, you have to know which of three deal structures you're signing, because each one shifts who fronts the money and when it comes back. The structure is the single biggest lever on your peak cash need — bigger than the construction cost itself in many cases.

Turnkey (landlord-built). The landlord or their chosen contractor builds to an agreed spec and hands you keys. You may pay a small "tenant improvement" charge baked into rent, but you don't front construction dollars and you don't wait for a reimbursement at all. Cash need: security deposit plus first/last month's rent plus your own furniture, fixtures, and equipment (FF&E), signage, and IT. For a 10,000 sq ft office or clinic, that's often $80K–$250K depending on how much FF&E you own. This is the lowest-cash path, and it's why credit tenants with no construction appetite push for it. The trade-off: less control over finishes, longer delivery timelines because you're in the landlord's queue, and rent that already amortizes the build.

Allowance (the reimbursement model). You or your contractor build, you pay the invoices as they come due, and the landlord reimburses up to a negotiated per-square-foot allowance once you hit defined milestones. This is the structure your question is about. You front 100% of the cost and wait to be made whole. The allowance is typically quoted as dollars per rentable square foot — common ranges run $25–$45/sq ft for second-generation office space, $40–$90/sq ft for medical or lab, and $15–$35/sq ft for light industrial or retail shell. If your actual build costs more than the allowance, you eat the overage permanently. If it costs less, you usually keep the difference or apply it to rent — read the clause carefully.

As-is. The landlord hands you the space in its current condition and contributes nothing. Every dollar is yours, and there is no reimbursement to wait for. Cash need equals full buildout cost plus operating runway. This is common in soft markets where tenants have leverage, and it's the cheapest rent but the heaviest cash draw. Some tenants take as-is deliberately to avoid landlord approval friction and long allowance-negotiation cycles, then amortize the build through a construction loan instead.

The hybrid you'll see most in 2027 leases is an allowance with a tenant-funded overage: the landlord caps its contribution, you fund everything above it, and only the allowance portion gets reimbursed. That means your peak cash need is the *total* build cost, and your recovery is only the allowance portion. Model both numbers separately — mixing them up is the most common cash-planning error in commercial lease negotiations.

One more structure worth naming: the allowance-as-credit. Instead of reimbursing you after the fact, the landlord applies the allowance as free rent or a rent abatement spread over the first 12–24 months. You never see cash, but you also never wait for a check. If your build is modest and your cash is tight, trading a lump-sum reimbursement for amortized free rent can be the difference between a deal that closes and one that doesn't. The landlord often prefers it too, because it avoids milestone disputes.

How to choose your cash strategy

The decision tree below walks through the practical sequence: identify the structure, estimate the fronted cost, layer on the reimbursement lag, then stress-test against your operating runway. Work it top to bottom — each branch changes the cash number materially.

The critical insight in that flow is that the reimbursement lag and the operating runway are *additive*, not overlapping. You need cash for both simultaneously, because your buildout is generating zero revenue while you're paying rent and payroll. A tenant who budgets only for the build cost and forgets the lag is the tenant who runs out of money in month three of a five-month wait.

Choosing between negotiating a bigger allowance and accepting a smaller one with faster milestones is a real trade-off. A landlord who won't budge on the per-square-foot number will often move on *timing* — agreeing to release 50% of the allowance at 50% completion rather than 100% at the end. That single change can cut your peak cash need by a third without costing the landlord a dollar more. Always negotiate the draw schedule, not just the headline allowance.

Concrete cost and timeline numbers

Here's where the question gets answered in dollars. The table below shows peak cash need for three representative 2027 buildout scenarios. These are planning ranges, not quotes — your market, trade mix, and lease terms will move them — but they're grounded in how these deals actually price.

Read the medical clinic row carefully, because it's the one that catches people. The build costs $640K. The landlord reimburses $480K. But the reimbursement doesn't arrive until 120 days after completion, and during those four months the clinic is paying $400K of operating costs with no patient revenue yet. Peak cash need is $1.04M — more than 1.6x the build cost. A tenant who raised only $640K is insolvent before the check clears.

The reimbursement lag is the number nobody models. In practice, commercial TI reimbursements run 60–120 days from substantial completion, and the tail is longer than the median. The clock usually starts at *substantial completion*, not at lease signing and not at permit issuance. Then the landlord's process adds friction: a third-party inspector's sign-off, lien waivers from every subcontractor, a reconciliation of the actual allowance against change orders, and finally accounts payable. Each step can add two to four weeks. If your lease ties reimbursement to *final* completion including punch-list items, add another 30–60 days. Build the lag into your model at 120 days even if the lease says 60 — the lease language and the actual payment date are different animals.

Operating runway during the wait. While you wait to be reimbursed, you're paying rent (often abated for a few months, then full), payroll, insurance, utilities, and any debt service. For a 20-person operation, that's realistically $60K–$120K per month all-in depending on market and compensation. Four to seven months of runway is the safe planning band. If your lease gives you six months of free rent, that runway shrinks — but free rent usually starts at *rent commencement*, which may itself lag completion, so don't double-count the relief.

Contingency. Hold 10–15% above your modeled peak. Construction overruns are the norm, not the exception, and change orders during a buildout routinely add 8–12% to the contract value. A 15% contingency on the clinic scenario above is another $96K–$156K of cushion. If you're financing the build with a construction loan, the lender will typically require a contingency line anyway, so plan for it from the start rather than discovering it at closing.

The 2027 timing wrinkle. If your buildout is scheduled for 2027, you're budgeting against a construction market you can't fully see yet. Material and labor costs have been volatile, and permit timelines in many metros have stretched. Two practical hedges: lock your contractor's pricing with a guaranteed maximum price (GMP) contract rather than a cost-plus arrangement, and start the permit process as early as the landlord will allow. Every month you shave off the pre-construction phase is a month of runway you don't have to fund.

Contract and handoff details

The lease language is where your cash plan either holds or breaks. The diagram below maps the milestone sequence that governs when money actually moves — and where tenants get stuck.

Three clauses deserve your attention before you sign, and each one has a direct cash consequence.

The reimbursement trigger. Find the exact event that starts the clock. "Substantial completion" is better for you than "final completion" or "certificate of occupancy plus punch list." If the lease says the landlord reimburses "within 30 days of receipt of a complete reimbursement package," the real question is what counts as complete — and landlords have wide discretion there. Negotiate a defined package list and a deemed-complete provision: if the landlord doesn't object within 15 business days, the package is accepted and the clock runs.

The allowance cap and what counts against it. Does the allowance cover hard costs only, or also design fees, permits, and FF&E? A $60/sq ft allowance that excludes design and permits is worth far less than one that includes them. Get the definition in writing and confirm whether unused allowance converts to free rent or evaporates. Also check whether change orders above the cap need landlord pre-approval — if they do, and you skip that step, the landlord can refuse to reimburse that portion entirely.

Lien waivers and the payment chain. Landlords withhold reimbursement until every subcontractor signs a lien waiver, because an unpaid sub can file a mechanic's lien against the property. That's reasonable, but it means your payment timeline depends on your general contractor's back-office speed. Use a GC who routinely produces conditional and unconditional lien waivers on a predictable schedule, and build that expectation into the contract. A GC who takes six weeks to collect waivers adds six weeks to your wait.

Handoff and closeout. After reimbursement, you still need to close out the project: as-built drawings, warranty documentation, equipment manuals, and a final reconciliation of your actual spend against the allowance. Keep a separate ledger for the buildout from day one — commingling build costs with operating expenses makes the reconciliation painful and can delay the final payment. If you're in a multi-tenant building, confirm how the landlord handles shared infrastructure like HVAC upgrades and whether any portion of your build benefits other tenants (which can affect who pays).

If the landlord is slow. Reimbursement obligations are contractual, and most leases include a late-payment or interest provision — but many tenants never invoke it. If payment runs past the stated window, a written demand citing the specific clause usually resolves it. Escalate to a formal notice only after that. The goal is the check, not the fight.

Related questions

What if the landlord's TI fund runs out before my reimbursement?

Allowance pools are sometimes capped at the building level, not per tenant. If earlier tenants exhaust the fund, your reimbursement can be delayed or reduced. Ask for written confirmation of the remaining pool balance and a clause subordinating other tenants' claims to yours.

Can I get the allowance paid in draws instead of a lump sum?

Yes, and you should ask. Milestone draws — 30% at framing, 30% at rough-in, 40% at completion — are common and cut your peak cash need substantially. Landlords resist because draws require more administration, so trade a slightly lower total allowance for a faster draw schedule.

Does the reimbursement count as taxable income?

Generally, a landlord allowance used for tenant improvements is treated as a reduction of rent or as a lease incentive rather than taxable income, but treatment varies by entity and jurisdiction. Confirm with your accountant before you model the after-tax cash position.

How does a construction loan interact with the TI reimbursement?

A construction loan funds the build, then you repay it with the reimbursement when it arrives. That converts your peak cash need into interest cost — often far cheaper than tying up equity. Lenders typically want an assignment of the reimbursement as collateral.

What happens if my buildout costs less than the allowance?

Depends entirely on the clause. Some leases let you keep the difference, some convert it to free rent, and some forfeit it. Negotiate for free-rent credit — it's the most common middle ground and it's real value even if it isn't cash.

FAQ

How many months of operating cash should I hold beyond the build cost? Plan for four to seven months of fully loaded operating costs — rent, payroll, insurance, utilities, and debt service. The reimbursement lag plus your pre-revenue period is what drives the number, and the lag alone can run 120 days. Six months is a reasonable default for most commercial buildouts.

Is the reimbursement lag really 60 to 120 days, or is that worst case? It's a realistic band, not a worst case. Sixty days happens when the landlord is organized and your GC produces lien waivers fast. One hundred twenty days is common when an inspector, a reconciliation dispute, or slow waivers intervene. Model 120 and treat anything faster as upside.

Should I negotiate a bigger allowance or a faster draw schedule? Faster draws usually win on cash flow. A $50/sq ft allowance paid in three milestone draws beats a $60/sq ft allowance paid in one lump sum 120 days after completion, because it cuts your peak funding need. Push for both, but prioritize timing if you can only get one.

Does free rent reduce how much cash I need on hand? Yes, directly. Free rent removes a real monthly outflow during the exact window when you're waiting to be reimbursed. Six months of abated rent on a $20K/month space is $120K you don't have to fund. Confirm when the abatement starts relative to completion.

What's the biggest mistake tenants make in modeling this? Budgeting only the build cost. The reimbursement lag and the operating runway are additive and simultaneous, so peak cash need routinely runs 1.5x to 1.7x the construction contract. Tenants who raise exactly the build cost run out of money mid-wait.

Can I start building before the lease is fully signed? Sometimes, under a work letter or early-access agreement, but you're taking real risk — if the deal falls through, you've funded construction on a space you don't control. Only do it with a signed early-access agreement that addresses reimbursement if the lease never closes.
