Diligence Coordination & the Closing Checklist

A signed letter of intent feels like the finish line. It is closer to the starting gun. Between a signed LOI and a funded loan sits a six-to-ten-week stretch in which a half-dozen third parties — an appraiser, a surveyor, an environmental consultant, tenants signing estoppels, a title company, and an escrow agent — must each finish independent work on their own schedule, in the right sequence, before a closing date that was picked before any of them started work. Nothing in assembling the underwriting package and nothing in the original deal-sourcing screen tells you how to run that stretch. This module does.

The broker's leverage here is not analytical, it is operational: a single tracking document, a willingness to chase people daily, and enough fluency in title, escrow, and closing-statement mechanics to catch errors before they become wire-day surprises. Deals far more often die from a missed due-diligence deadline, an unresolved title exception, or an estoppel that never came back than from a bad cap rate.

The LOI is a term sheet, not a contract. Its substantive deal terms — price, structure, major conditions — are generally non-binding, while specific carve-outs the parties intend to be enforceable (confidentiality, exclusivity/no-shop, cost allocation, occasionally a break-up fee) bind immediately upon signature. The purchase and sale agreement (PSA), typically drafted by buyer's counsel and negotiated over one to three rounds of redlines in the two to four weeks after LOI execution, is the actual binding contract — and it is the PSA's execution date, not the LOI's, that starts every diligence clock.

Four PSA terms deserve a place on the broker's master timeline the day the PSA is signed. The earnest money deposit structure — often split into an initial deposit at PSA execution and an additional deposit at due diligence expiration — and whether it is refundable or already "hard." The due diligence period length (commonly 30–45 days for a stabilized asset, 45–75 days for value-add or complex title/environmental situations) and its expiration date, which is the single most consequential date in the file: after it passes, the buyer's walk rights generally disappear absent negotiated survival provisions. The closing date and extension options, usually requiring written notice a fixed number of days in advance and often an extension fee. And the remedies on default — typically liquidated damages capped at the deposit if the buyer defaults, and specific performance rights for the buyer if the seller defaults. Build the timeline by working backward from the DD expiration and closing dates, and put it in front of every principal and consultant the same day the PSA is executed.

Five workstreams run in parallel, not in sequence, and each has its own turnaround and its own failure mode.

The appraisal is ordered by the lender, often through an approved panel or appraisal management company under arm's-length ordering rules that bar the broker from selecting or pressuring the appraiser. Turnaround runs three to four weeks, which usually makes it the long pole in the schedule — order it the day the PSA (and any rate lock) is in hand, not the day due diligence formally opens. The ALTA/NSPS survey, ordered directly from a licensed surveyor, takes two to four weeks depending on parcel size and site access, and is what lets the title company remove the standard survey exception and issue extended coverage. The Phase I Environmental Site Assessment, combining a site visit with a records review, typically takes two to three weeks; a finding of a "recognized environmental condition" (REC) triggers a Phase II soil or groundwater investigation that can add three to six weeks and is one of the most common reasons a due diligence period gets extended.

Estoppel certificates — tenant-signed statements confirming lease terms, current rent, and the absence of landlord default or undisclosed side letters — are drafted by seller's counsel from the lease abstract and sent to tenants, who typically have ten to twenty business days to respond under the lease's estoppel clause. Many leases attach no penalty to tenant non-response, so non-institutional tenants routinely need direct, repeated follow-up from the broker or property manager; a handful of holdouts is often resolved with a landlord (seller) estoppel in lieu, usually capped by the loan documents at some percentage of total GLA or NOI. SNDAs (Subordination, Non-Disturbance, and Attornment agreements), required by the buyer's lender from major tenants so the mortgage can subordinate to the tenant's occupancy rights in exchange for the tenant's agreement to attorn to the lender on foreclosure, should start on day one alongside estoppels rather than after them — sophisticated anchor and credit tenants frequently redline the lender's SNDA form hard enough to make this the slowest workstream in the file. A single tracker — party, item, date ordered, date due, date received, status — updated and circulated at least weekly, more often as closing nears, is what keeps five parallel workstreams from silently diverging.

Escrow opens the same day the PSA is executed, with the earnest money deposit wired into an interest-bearing account held by a neutral escrow agent (frequently the title company). The title company pulls a title commitment: Schedule A confirms vesting, legal description, and the proposed insured; Schedule B lists every exception of record — liens, easements, CC&Rs, the seller's existing loan, unresolved mechanic's liens, unpaid taxes — that must be cleared, subordinated, or affirmatively insured over before a clean policy issues. Buyer's counsel reviews the commitment against the survey and sends a title objection letter, typically within ten to fifteen days of receiving both, flagging every exception it will not accept. The closing lender requires its own lender's title policy, separate from the buyer's owner's policy, along with specific endorsements — comprehensive, zoning, tax parcel, contiguity, non-imputation — that should be negotiated with the title company well before closing, since some require underwriting review time of their own.

On closing day itself, no one is literally sitting at a table. In a standard "close in escrow," the buyer wires funds and delivers signed loan documents, the seller delivers a signed deed, assignment of leases, bill of sale, and FIRPTA affidavit into escrow in advance, and the escrow agent confirms every condition in both parties' closing instructions is satisfied before simultaneously recording the deed and mortgage and disbursing funds. Recording — not the wire — is what makes the transaction legally final.

The closing (settlement) statement is the accounting of the entire deal: every dollar assigned as a debit (a charge to that party) or a credit (money that party is owed, or has already paid), structured so debits and credits net out identically on both the buyer's and seller's sides. The purchase price is a debit to the buyer and a credit to the seller; the earnest money deposit already sitting in escrow is a credit to the buyer, since it applies toward the price; new loan proceeds credit the buyer; payoff of the seller's existing debt debits the seller; and prorations for taxes, rent, expense reimbursements, and utilities run as a credit to one side and a matching debit to the other, direction depending on whether the item is billed in arrears or in advance. Transfer taxes, recording fees, and title premiums are allocated by local market custom, which the broker should confirm rather than assume.

Fee collection at closing works the same way: the broker gets paid by explicit written instruction to escrow, not automatically. Before closing, the brokerage should deliver a standalone commission instruction letter or invoice to the title/escrow company — naming the brokerage, its W-9/TIN, the exact dollar amount or formula and the transaction value it applies to, and wiring instructions — so the fee appears as its own line item on the closing statement. Relying on the LOI's fee language alone is a common and avoidable mistake: LOIs are frequently non-binding, get superseded by the PSA, and typically carry no payment mechanics escrow can act on. Confirm the fee line item is present the moment the draft closing statement first circulates, not after the deal has already recorded.

Assume the property carries $146,000 in annual property taxes for the 2026 calendar tax year (365 days; 2026 is not a leap year), and the local taxing authority bills in arrears — the 2026 tax bill will not be issued or paid until early 2027. Closing is scheduled for July 16, 2026, and the escrow instructions, as is standard, treat the buyer as owner of record beginning on the day of closing itself.

Step 1 — daily rate. $146,000 ÷ 365 days = $400.00 per day.

Step 2 — seller's days. The seller owns the property from January 1 through July 15 (the day before closing): 181 days across January–June (31+28+31+30+31+30) plus 15 days in July = 196 days.

Step 3 — buyer's days. 365 − 196 = 169 days, covering July 16 through December 31.

Step 4 — dollar allocation. Seller's share: 196 × $400 = $78,400. Buyer's share: 169 × $400 = $67,600. The two shares sum to $146,000, confirming the math ties out.

Because the bill has not yet been paid and the buyer will be the one who eventually writes the check to the taxing authority for the full 2026 amount, the seller owes the buyer a credit for the seller's 196 days of ownership. The closing statement carries this as a $78,400 debit to the seller and a $78,400 credit to the buyer — cash that reduces the seller's net proceeds and reduces the buyer's cash due at closing by the identical amount.

Rent runs the opposite direction from arrears-billed taxes, because commercial rent is typically collected in advance on the first of the month. Assume the property generates $93,000 in gross rent for July 2026 (31 days), and the seller collected the entire amount from tenants on July 1 as usual.

Step 1 — daily rate. $93,000 ÷ 31 days = $3,000.00 per day.

Step 2 — seller's earned days. The seller owned and operated the property from July 1 through July 15: 15 days × $3,000 = $45,000, which the seller is entitled to keep.

Step 3 — buyer's earned days. The buyer owns the property from July 16 through July 31: 16 days × $3,000 = $48,000. Since 15 + 16 = 31 and $45,000 + $48,000 = $93,000, the allocation accounts for the full month.

Step 4 — the credit. Because the seller already collected and holds the full $93,000, the seller must credit the buyer $48,000 at closing — the buyer's share of rent the seller was never entitled to keep. This appears on the closing statement as a $48,000 debit to the seller and a $48,000 credit to the buyer.

Security deposits are not prorated at all — they transfer to the buyer dollar-for-dollar, in full, regardless of the closing date, because the buyer is assuming the landlord's contractual obligation to return them to tenants at lease end. If tenants have posted $38,500 in aggregate security deposits, that full amount is credited to the buyer (and debited to the seller) as its own line item, kept separate from the rent proration above rather than blended into it.
