Selling Alarm Monitoring Accounts in 2026: What Buyers Pay and How the Deals Actually Work

An account sale transfers your monitoring contracts and the recurring revenue attached to them. The buyer takes over billing, monitoring, and service for those customers. You keep your company — the entity, the licenses, the trucks, the install pipeline. It's the cleanest liquidity event in this industry, and it's how a lot of dealers fund growth, retirement, or a pivot into commercial work.

I built over 800,000 customer accounts at Protect America across 23 years in this industry, and here's the first thing to understand: the buyer is not buying revenue. They're buying the probability that each account keeps paying for years. Every mechanic in these deals — the price, the diligence, the holdback — exists to price that probability.

Verified 2026 transaction data puts monitoring books at 30-50x monthly RMR, with quality commercial books at 35-45x. A book producing $25,000 a month sells for roughly $750,000 to $1.25 million across that full range. Where you land depends on attrition history, contract strength, account age, geographic density, and how clean your records are.

Three kinds of buyers show up. Regional dealers in your footprint who can fold your accounts into a branch they already run — often the best payers, because density makes your accounts cheaper for them to service. National consolidators running acquisition programs — professional, fast, and disciplined on price. And monitoring-centric companies that buy books as their core business model.

Multiple bidders change your outcome more than any negotiating tactic. A book shopped to one buyer gets one opinion of its value. A book shown to three gets a market.

Expect the buyer to pull the book apart account by account. Diligence on an account sale typically covers:

• ▸Contracts — signed, current, assignable agreements for every account, with remaining term noted.
• ▸Cancellation logs — your real attrition rate computed from history, not the number you quote.
• ▸Payment records — autopay penetration, delinquencies, and rate-increase history.
• ▸Monitoring data — signal history proving the accounts are alive and online.
• ▸Account demographics — age of accounts, residential versus commercial mix, geographic spread.
• ▸Liens and encumbrances — confirmation the accounts aren't already pledged to a lender.

Every gap they find becomes a price adjustment. Missing contracts get carved out of the deal entirely. The sellers who get top-of-range prices are the ones whose files make diligence boring.

Nearly every account sale includes a holdback: the buyer pays most of the price at closing and holds a portion in escrow for a defined period. If accounts cancel beyond an agreed threshold during that window, the buyer keeps some of the escrow to offset the loss. That's the attrition guarantee — you're warranting that the book you sold is the book they get.

Holdbacks are standard practice; there's no fixed market size. The percentage held, the length of the guarantee period, the attrition threshold that triggers clawbacks, and how replacement accounts are credited are all negotiated deal by deal. What matters is that every one of those levers moves real money, so negotiate them as hard as the headline multiple. A high multiple with a punitive holdback can net less than a moderate multiple with clean terms.

Industry-typical attrition runs roughly 10-13% a year; under 10% marks a healthy book. Buyers price this ruthlessly because it's the exact rate their investment evaporates. A sub-10% book with strong contracts pushes toward 35-45x. A book churning above the typical range fights to stay near the floor — and takes tougher holdback terms on top of the lower multiple.

If your attrition is ugly, twelve months of retention work before going to market pays twice: a better multiple on a bigger book, and a friendlier guarantee because your history supports it.

An account sale and a company sale are different transactions with different math. Sell just the book and you get RMR pricing — 30-50x monthly — while keeping your entity and install business. Sell the whole company and buyers switch to EBITDA math: roughly 3-5x for project-heavy shops, 5-9x for regionals with a management team and 35-50% recurring revenue.

If you sell the whole company as a hybrid, watch the blend trap: buyers love to absorb the monitoring book into one EBITDA number and underpay the RMR-heavy side of the business. Make the book's value explicit in any whole-company deal, or carve it out and sell it separately.

1. ▸Shopping the book to a single buyer and accepting the only opinion of value in the room.
2. ▸Anchoring on inflated multiple charts instead of verified 30-50x transaction data, then souring on real offers.
3. ▸Ignoring holdback terms while negotiating the headline multiple — the escrow terms decide what you actually collect.
4. ▸Going to market with missing contracts and messy billing, then donating price adjustments in diligence.
5. ▸Selling while attrition is spiking instead of fixing retention first and selling a healthier book.
6. ▸Signing a non-compete broad enough to strangle the install business you kept.

The buyers do this every month. Most sellers do it once in a lifetime. That asymmetry — not the multiple — is where sellers lose. Level it: audit your own book before they do, fix what diligence would find, know your real attrition number, and bring competition to the table. Sellers who prepare eighteen months out routinely clear terms that unprepared sellers never get offered.
