Most due diligence failures are not analytical. They are scheduling failures.
The work itself is well understood — inspect the building, verify the income, read the leases, price the capital needs. What catches buyers out is ordering it badly: commissioning the survey in week three, discovering the estoppels are still outstanding on the final day, or finding a structural issue after the deposit has already gone hard. A 30-day period is enough time if the sequence is right and tight if it is not.
Week One: Order Anything With a Lead Time
The first days should be spent placing orders rather than reading documents. Third-party reports run on other people’s calendars, and every one of them started late compresses the end of the period.
Engage the property inspection and, separately, a licensed contractor for the building systems. Order the Phase I environmental assessment if the property or its neighbours suggest one is warranted — a former dry cleaner or petrol station next door is the classic trigger. Open title and order the survey. Request insurance quotes now rather than at the end, because in California availability can take longer than pricing.
Simultaneously, send the document request to the seller in full. A partial request produces a partial response and a second round of waiting.
Week Two: Verify the Income
With reports in motion, turn to what the property actually earns. Reconcile the rent roll against the leases themselves rather than against the seller’s summary — check the stated rent, the term, the deposit held, and any concession that does not appear on the roll.
Then reconcile the rent roll against the bank deposits. Contracted rent and collected rent are different numbers, and the gap between them is one of the more informative figures in the whole exercise. A building with strong paper rents and a persistent collection shortfall is a different asset from the one described in the marketing.
This is also the point to issue tenant estoppel certificates. They take time to come back, they frequently come back inconsistent with the rent roll, and every discrepancy needs an explanation before closing.
Week Three: Price the Findings
By now the inspection and contractor reports should be in hand. The task is converting observations into numbers: what must be addressed immediately, what can be scheduled over the hold period, and what is genuinely cosmetic.
Get real bids for the material items rather than estimating them. A roof described as “near end of life” is not a number, and the difference between a repair and a replacement is often the difference between proceeding and renegotiating. Rebuild the operating expense line at the same time, with the reassessed property tax figure and the actual insurance quote replacing the seller’s historical numbers.
Title should also have been reviewed by this stage — easements, encroachments, and any recorded agreement that constrains use or future development.
Week Four: Decide, Renegotiate, or Withdraw
The final week is for the decision, not for discovery. If the findings support a price adjustment or a seller credit, the conversation needs to happen with days remaining, not hours — a request made on the last afternoon reads as leverage rather than diligence, and tends to be received that way.
Confirm the loan is tracking to the same calendar. Appraisals are ordered by the lender and can arrive later than expected, and a financing contingency that expires before the appraisal lands is a genuine risk rather than a technicality.
Where Timelines Actually Break
Waiting on the seller. Documents arrive in instalments, and each gap consumes days. Build a deadline for delivery into the agreement rather than relying on goodwill.
Sequential rather than parallel work. There is no reason for the environmental report to wait on the inspection. Run everything that can run concurrently.
Occupied-unit access. Tenants must be given proper notice, and coordinating interior access across a fully occupied building takes longer than buyers expect. Schedule it in the first week.
Estoppels returning late or wrong. They depend on tenants responding, which cannot be forced. Send them early enough to allow a second round.
Questions About Due Diligence Timing
Is 30 days enough for a small multifamily property?
Usually, provided the third-party reports are ordered in the first few days and the seller’s documents arrive promptly. Where an environmental report is needed, or the building is fully occupied and access must be coordinated, a longer period is more realistic than an extension requested halfway through.
What should be ordered on day one?
Anything controlled by a third party: inspection, contractor assessment, environmental report if applicable, title and survey, and insurance quotes. Document review can happen at any point, but a report you have not commissioned cannot be accelerated later.
When should a price adjustment be raised?
As soon as the findings are priced and defensible, which normally means once contractor bids are in. Waiting until the contingency is about to expire weakens the position and invites the seller to treat it as an attempt at re-trading rather than a substantiated request.
Do estoppels really matter on a small building?
Yes, and arguably more, because a single misstated tenancy is a larger proportion of the income. The estoppel is where you learn about the verbal agreement on parking, the deposit that was never collected, or the rent that differs from the roll — none of which appear in the seller’s paperwork.
