Complete guide to buying a cannabis business

The ten phases at a glance

A cannabis acquisition is a sequence with two gatekeepers you do not control: the seller and the regulator. The phases below put the cheap, decisive checks first and the expensive work last. Durations are general deal practice, not a survey, and the approval phase depends on the state.

Phase	Typical time	What it produces	Stop if
1. Define the buy box	1 to 2 weeks	Written criteria and a budget	You cannot name a state and license type
2. Pre-clear your eligibility	2 to 4 weeks	An ownership chart the regulator will accept	An owner or investor cannot pass
3. Line up capital	3 to 6 weeks	Proof of funds and a debt plan	The cash portion is not real
4. Source and screen targets	1 to 4 months	A short list under NDA	Nothing fits the box
5. Price it and sign an LOI	2 to 6 weeks	Exclusivity on one target	The license cannot transfer to you
6. Diligence	6 to 10 weeks	A verified picture, or a re-price	Revenue or tax does not tie out
7. Purchase agreement	In parallel with 6	Signed agreement, application ready	No approval condition or no outside date
8. Regulatory and local approval	3 to 12 months	Written approval	Approval is denied or the outside date passes
9. Closing	1 day, 2 weeks of prep	Ownership	A closing deliverable is missing
10. First 90 days	13 weeks	A stable, compliant business	Not applicable

The buy a cannabis business pillar explains what each of these topics is. This guide is the order of operations, with a checklist for each phase.

Phase 1: Define the buy box

Write your criteria down before you look at a single deal. A buyer without criteria evaluates everything and closes nothing.

Checklist:

• One or two target states. Each state is its own legal system, so a national search is really several separate searches. Limited-license vs open-market states explains how the state choice drives price and risk.
• License type. Retail, cultivation, and manufacturing earn money differently; see cannabis business models explained.
• Size range by revenue and by earnings, and whether you will buy a pre-revenue license.
• Total budget split five ways: price, inventory, transfer and professional fees, working capital through the approval wait, and deferred capital spending.
• Your role: owner-operator, owner with a hired general manager, or passive investor. Regulators vet all three, but sellers and lenders treat them differently.
• A return target stated on after-tax cash flow. Adult-use earnings are still taxed under 280E, so an EBITDA target alone will mislead you.

Phase 2: Pre-clear your own eligibility

Run diligence on yourself before you run it on anyone else. It costs a few hours of a cannabis attorney’s time and removes the most expensive failure: a denial after months of work.

Checklist:

• Draw the ownership chart you would file, down to natural persons. Include lenders, investors, spouses where the state counts them, and anyone with a profit share.
• Check each person against the target state’s disqualifying-offence, prior-revocation, and tax-compliance rules. Details by example state are in ownership eligibility, background checks, and residency.
• Check the approval threshold. Massachusetts requires Commission approval before a person acquires 10% or more of a licensee or gains control.
• Check residency. Washington still requires licensees to have lived in the state for at least six months.
• Count the licenses you and your investors already hold against the state’s cap; see ownership caps and residency rules by state.
• Collect now what every application asks for: government ID, fingerprints where required, personal tax returns, bank statements showing the source of funds, and organizational documents for the buying entity.

Exit test: every person on the chart is approvable, or has been removed from it.

Phase 3: Line up capital

Know exactly where every dollar comes from before you make an offer. SBA SOP 50 10 8, effective 1 June 2025, makes marijuana businesses ineligible for 7(a) and 504 loans, and conventional banks do not make acquisition loans to them.

What is left is mostly debt from non-bank sources. Debt made up about 94.8% of capital raised by U.S. licensed operators in 2025, according to Viridian Capital data reported by MJBizDaily. For a single-location purchase the realistic stack is buyer cash, a seller note, and sometimes private investor equity.

Checklist:

• Proof of funds in the name of the entity that will pay, dated within 30 days.
• A target structure: cash at close, the seller note you will ask for, and what you can offer as security. See seller financing in cannabis deals.
• Signed commitments, not conversations, from any investor. Each one goes on the Phase 2 chart.
• A debt-service test on after-tax cash flow, not EBITDA.
• A reserve for the approval wait, when your deposit is committed and you do not yet receive the cash flow.

Illustrative: a store with $600,000 of EBITDA that keeps $330,000 after federal and state tax can carry a $1,000,000 seller note at 9% over six years, which costs about $216,000 a year, and still leave about $114,000. The same note against the $600,000 figure looks comfortable and is not. The full menu of sources is on cannabis acquisition financing options.

Phase 4: Source and screen targets

Good licensed businesses rarely appear on public listing sites, so work several channels at once and screen hard.

Sourcing checklist:

• Brokers and intermediaries in the target state, each given your one-page buyer profile.
• Cannabis transactional attorneys and CPAs, who know which clients are ready to leave.
• Direct, discreet letters to license holders drawn from the regulator’s public license list.
• Receivers, assignees, lenders, and landlords for distressed situations; see buying a license out of receivership.

Screening checklist, from the blind summary and a first call, before you spend money:

• Is the license type and location inside the buy box?
• Is the license transferable now, or is there a holding period or social equity condition?
• Does the seller own or lease the real estate, and how many years remain on the lease?
• Are tax returns filed for every year?
• Why is the owner selling, and will the owner stay for a transition?
• Does the asking price make sense against after-tax cash flow? The framework is on how to evaluate a cannabis business for sale.

Sign the NDA, then ask for three years of financials, the license and local permit, the lease, and a monthly sales report from the point-of-sale system. That is enough to price an offer.

Phase 5: Price it and sign a letter of intent

Make the offer from your own model, not from the asking price. Normalize earnings, subtract federal tax as it is actually owed, and apply a multiple that fits the license’s scarcity. The method is on the valuation pillar.

LOI checklist:

• Asset or equity purchase. In California a license cannot be assigned, and a buyer replacing every existing owner needs a new license before operating, so structure is often dictated by the rules. See asset sale vs membership-interest sale.
• Price, cash at close, seller note terms, and any earn-out formula.
• Inventory: counted at closing, priced at cost, with a cap and an exclusion for aged or untested product.
• Deposit amount, who holds it, and what happens on regulatory denial or delay.
• Exclusivity. General M&A guidance puts it at 30 to 90 days, with buyers asking for 45 to 90. Ask for enough time to finish diligence and sign the purchase agreement.
• Who pays the application and transfer fees.
• A diligence access clause: data room within a set number of days, and read-only track-and-trace reports.

Clause-by-clause guidance is in the letter of intent guide.

Phase 6: Diligence

Work in the order that kills a bad deal cheapest: transferability, revenue, tax, real estate, compliance, then everything else.

Checklist:

• Transferability. Read the state rule, the local ordinance, and the license conditions yourself. Confirm every past ownership change was approved.
• Revenue. Tie point-of-sale totals to track-and-trace sales, bank deposits or vault logs, and sales and excise tax returns for the same months. The method is on verifying revenue with track-and-trace data.
• Inventory. Compare a physical count to the track-and-trace record. California treats a 5% gap as a significant discrepancy that must be reported.
• Tax. Federal, state, excise, sales, and payroll returns for every open year, with proof of payment and any payment plans or liens. How to read the statements is in cannabis financial statements under 280E.
• Real estate. Zoning letter or permit, buffer compliance, lease term, cannabis use clause, assignment and change-of-control language.
• Compliance. Inspection reports, notices of violation, fines, and pending matters.
• People. Employee roster, badge status, wage claims, and who holds the system administrator rights.
• Contracts and brand. Vendor agreements, brand licences, equipment leases, and UCC lien searches.

Put every finding into one of three piles: walk away, re-price, or cover with an indemnity and holdback. The full request list is the cannabis due diligence checklist, and the stop signs are on red flags when buying a cannabis business.

Phase 7: The purchase agreement

Negotiate the agreement while diligence runs, so findings go straight into the draft.

Checklist:

• Regulatory and local approval as conditions to closing, with an outside date. Build it from the regulator’s clock: Missouri’s rule allows up to 150 days to decide an ownership change of 50% or more, measured from a complete application. See regulatory-approval contingencies.
• Landlord consent as a condition, with a deadline.
• Representations on compliance, tax, track-and-trace accuracy, and disclosed ownership.
• A specific tax indemnity and a holdback sized to the exposure found in Phase 6; see tax liabilities and holdbacks in a sale.
• Covenants for the wait: ordinary-course operation, inventory levels, monthly reporting, notice of inspections.
• Purchase-price allocation agreed in an asset deal.
• Seller non-compete and a paid transition period.
• The ownership-change application, drafted and ready to file within days of signing.

Phase 8: Regulatory and local approval

This is the longest phase and the one where buyers do the most damage by being impatient. Practitioner reports published in April 2026 put approval at 90 to 120 days in Michigan for previously vetted principals, 4 to 8 months in Colorado, and 6 to 12 months for full ownership changes in California.

Checklist:

• File a complete application and pay the fee. New Jersey charges $20,000 for a transfer of more than 50% of ownership; Massachusetts charges $5,000 per entity, per licence for a change of control.
• Answer deficiency letters within days. One named person on each side.
• Do not take control. No signing authority on bank accounts, no hiring or firing, no profit share, unless it sits inside an arrangement the state permits. See interim management services agreements.
• Read the seller’s monthly reports and compare them to the diligence period. A slide in sales is a conversation now, not at closing.
• Use the time: open the bank relationship, bind insurance quotes, line up the security and point-of-sale vendors, and draft employee communications.
• Watch the outside date and decide early whether you would extend.

State timing tables are in the LOI-to-close timeline.

Phase 9: Closing

Closing is a list of deliverables, and nothing funds until each is in hand.

Checklist:

• Written state approval and any local approval or permit reissue.
• Physical inventory count, reconciled to track-and-trace and priced under the agreed method; see inventory and biomass at closing.
• Lien payoff letters and UCC terminations.
• State tax clearance certificates, or the holdback funded in their place.
• Landlord consent and the lease assignment or new lease, signed.
• Note, guaranty, pledge, and security documents.
• Insurance bound in the buyer’s name from the effective time.
• A funds-flow memo both sides have signed off on.
• Administrator credentials for track-and-trace, point of sale, security, and alarm systems.

The sequence of the day itself is on closing on a cannabis business.

Phase 10: The first 90 days

From the effective time, every compliance event is yours.

When	Do this
Day 1	Change system administrators, alarm codes, safe combinations, and cash custody. Meet the staff.
Week 1	Confirm the bank account is live. Register or update excise and sales tax accounts. File any post-closing notices the state requires.
Weeks 2 to 4	Update employee badges or agent cards. Run your own full inventory audit. Review vendor terms.
Days 30 to 60	Close the first month’s books on a 280E basis and set estimated tax payments. Reconcile the closing inventory adjustment.
Days 60 to 90	Finish required training; Massachusetts requires agents who handle or sell marijuana to complete Responsible Vendor Training within 90 days of hire. Decide what to change, and check which changes need prior regulator approval.

Use the seller’s transition period while you have it, and calendar every holdback release and note payment date. The week-by-week version is on first 90 days after buying.

Where buyers lose deals, and the phase that prevents it

Failure	Where it shows up	Phase that prevents it
An owner or investor fails the background review	Approval	Phase 2
Funding falls short at signing	LOI or agreement	Phase 3
License cannot transfer to the buyer’s entity	At filing	Phase 5
Revenue does not tie to track-and-trace	Diligence	Phase 6
Seller’s unpaid tax follows the buyer	After closing	Phase 6 and Phase 7
Landlord refuses consent	After LOI	Phase 6 and Phase 7
Buyer takes control early and draws a violation	Approval wait	Phase 8
No bank account on day one	After closing	Phase 8

More examples are on mistakes cannabis buyers make. A broker will typically start a buyer at Phases 1 to 3, testing the buy box, the ownership chart, and the funding plan against the target state’s rules, which you can talk through on a free 20-minute intro call.
