What to know

What to know about buying a security business in Texas

Houston, Dallas-Fort Worth, Austin and San Antonio carry most of the market: professional services, retail, home services, manufacturing, software, construction trades, healthcare and logistics, with energy services concentrated in Houston and the Permian Basin. Texas has no personal income tax but levies a franchise tax on margin for most entities above a revenue threshold. General contractor licensing is handled locally, while electricians, plumbers and HVAC contractors are licensed by the state. Non-compete agreements are enforceable within limits, and sales tax reaches some services. SBA 7(a) lending is active through many banks, with district offices in Dallas, Houston, San Antonio, El Paso, Lubbock and Harlingen.

Security listings in Texas on Rejigg include guard services, alarm and monitoring companies, and security technology providers. Buyers of these businesses look at recurring monitoring contracts, licensed staff, and customer tenure. Plan for state licensing, staff turnover, and contract assignment terms.

Due diligence

What to Look For

Practical guidance from hundreds of real acquisition conversations.

Recurring vs. Project Revenue

Ask for a revenue breakdown separating monitoring contracts, managed security service agreements, annual software subscriptions, and maintenance agreements from one-time installation and project work.
The contracted, repeating income is what drives premium valuations — project work matters too, but it has to be re-won each cycle.
Monitoring contracts and managed service agreements that renew without re-selling are the single most important revenue quality signal across all security sub-categories.

Credentials and Clearances

Understanding exactly who holds which credentials and whether those people plan to stay is one of the most important due diligence questions in this category.
Security clearances, particularly high-level ones, take years to obtain and cannot be quickly rebuilt after a sale.
Low-voltage licenses, manufacturer certifications, and CISSP or similar credentials are genuine competitive advantages that transfer with the people who hold them.

Contract Depth and Transfer

Ask to see the contract list with expiration dates, renewal history, and what each agreement says about ownership transfers.
Long-term contracts — whether multi-year government agreements, commercial service agreements, or monitoring subscriptions with auto-renew — separate a company with stable income from one riding on project volume.
Government contracts require additional care, since some require formal approval or re-certification when ownership changes.

Equipment and Integration Stickiness

Ask what percentage of clients have installed equipment and what the renewal rates look like on service and monitoring agreements covering those systems.
In physical security and security technology, installed equipment creates a loyalty effect buyers can get genuinely excited about — cameras, access control panels, and intrusion systems wired into a building are expensive and disruptive to replace.
When clients have your hardware in their walls and your software in their workflows, they tend to stay.

Team and Operations Independence

Ask who handles each major client relationship and what happens to operations if the owner steps away for a month.
The best security acquisitions run without the owner dispatching every job — whether it's a security operations center staffed around the clock, a dispatcher routing technicians independently, or an operations manager who handles installs and client calls without the founder.
Management depth is what makes a security business truly transferable.

Valuation

What Should You Expect to Pay?

3x-5x

SDE

Owner-operated, project-heavy, limited contracts

5x-10x

EBITDA

Strong recurring contracts, credentialed team, independent operations

Security businesses land across a wide range because the difference between a company with a cleared team and multi-year government contracts versus one dependent on one-off installation projects is enormous from a risk and cash flow standpoint.

What drives a premium

Multi-year service or monitoring contracts with documented renewal history

A team with transferable security clearances, manufacturer certifications, or specialized licenses

Installed equipment at client sites creating high switching costs and sticky recurring revenue

Operations manager or security operations center that runs independently of the founder

Security Businesses in Texas

How do I contact the owner of a business I found on Rejigg?

Create a free Rejigg account; owners, and the brokers who run some sales, only hear from buyers through the platform. Open the listing to see the full profile: city, team size, financials, what is for sale, and the reason for selling. Sign Rejigg's standard Fee & Confidentiality Agreement for that business; it is the same form for every deal. Verify your phone, then send your pitch from the listing. Replies, meetings, and documents all run through Rejigg.

Can I email Rejigg to get introduced to an owner?

No. Rejigg does not forward emails to owners or brokers, so a note to support@ or hello@ with a listing link will not reach them. Create a free account, open the listing, sign the agreement for that business, verify your phone, and send your pitch; that reaches them in a few minutes.

How does buying a business on Rejigg work?

Create a free account, set your criteria, and browse off-market businesses sourced directly by our team. When you find a match, reach out to the owner through the platform, Rejigg handles NDAs, scheduling, and document sharing so you can focus on the deal.

How much does it cost to buy a business?

Prices vary widely; most small businesses on Rejigg sell for $500K to $10M. Beyond purchase price, budget for diligence costs (attorney and accountant fees, typically $10K-$50K) and working capital reserves. Getting started on Rejigg is free.

What financing options are available?

The most common path is an SBA 7(a) loan, covering up to 90% of the purchase price with 10-year terms. Seller financing is also common, where the seller carries a note for 10-30% of the price. Our SBA loan calculator helps you estimate monthly payments.

How is Rejigg different from a broker or marketplace?

Brokers represent the owner and typically charge the owner 5–10% of the sale price. Marketplaces list whatever gets posted. Rejigg vets every listing, sources many of them directly through our own owner outreach, connects you directly with owners when they sell directly, and gives you tools to manage the process from first contact through closing.

What is due diligence and what does it involve?

Due diligence is the verification process after you and the owner agree on terms (usually in a Letter of Intent). Budget 30-60 days and $10K-$30K for professional help. A Quality of Earnings report is increasingly common for SBA-financed deals.

Can I buy a business with no money down?

Rarely. Most acquisitions require 10-20% down, whether through SBA financing, seller financing, or cash. Some creative structures can reduce the cash needed upfront, but sellers generally want to see you have skin in the game.
