IT Support for Houston Real Estate Brokerages: Stop Wire Fraud (2026)

Real estate combines three things criminals look for: large, predictable payments, many people on every deal, and a lot of trust in email. A typical Texas transaction involves the listing agent, buyer's agent, lender, title company, and clients, all trading documents on a deadline. Industry reporting has ranked real estate wire fraud among the costliest forms of business email compromise for years. Brokerages also tend to have the weakest controls in that chain, because agents are independent contractors who bring their own laptops, phones, and habits.

The fallout lands on the brokerage even when an agent's personal account was the weak point: angry clients, E&O claims, damaged referral relationships, and questions from your title partners about how the breach happened.

Most real estate wire fraud follows the same steps. An attacker phishes an agent or transaction coordinator, quietly reads their email, and waits for a closing. Then they add a hidden forwarding rule, spoof or hijack a thread, and send "updated" wiring instructions to the buyer. You can break that chain in several places:

• Phishing-resistant sign-in. Require multi-factor authentication on every brokerage mailbox, and prefer app-based or passkey methods over text messages.
• Mailbox monitoring. Alert on new forwarding rules and suspicious sign-ins. Our guide to malicious inbox rules in Microsoft 365 shows what to look for.
• Out-of-band verification. Every client gets the same written notice at contract: the brokerage will never send or change wiring instructions by email, and they should call the title company at a number they found independently.
• Coordination with title. Align your process with your title partners. Our article on title company escrow and wire fraud security explains the controls on their side of the closing.

For the broader defense, see business email compromise defense for Texas finance teams; the same tactics apply to closings.

You cannot force independent contractors onto company laptops, but you can control brokerage data. Give every agent a brokerage email account instead of letting deals run through personal Gmail or Yahoo addresses. Use mobile app protection so transaction documents stay inside managed apps and can be wiped when an agent leaves, without touching their personal photos. A short BYOD policy with app protection sets expectations agents will actually accept.

Shared logins are the other common leak. Lockbox, MLS, e-signature, and transaction-management credentials often live in a spreadsheet or group text. A password manager rollout fixes that and makes access easy to revoke.

Texas brokers are required by TREC rules to keep transaction records for a set period, and those files are full of personal information: driver's licenses, bank statements, Social Security numbers on lender forms, and signed contracts. Confirm current retention requirements with your compliance resources, then make sure those records are both kept and protected. That means encrypted storage, access limited to the people who need it, and backups that ransomware cannot reach.

If transaction files sit in Microsoft 365 or a cloud drive, do not assume the provider is backing them up for you. Read our Microsoft 365 backup guide and the 3-2-1-1-0 immutable backup rule. If a mailbox is compromised, Texas notification requirements may apply; the Texas data breach notification law overview explains the deadlines.

Agents join and leave brokerages often, and each move is a security event. A departing agent who keeps access to the brokerage mailbox, the shared drive, or the transaction platform can take client lists with them or leave a compromised account behind. Build a repeatable checklist: create accounts with the right access on day one, enroll MFA before the first deal, and remove access the day an agent hangs their license elsewhere. Our offboarding and deprovisioning checklist adapts well to contractor turnover. Brokerages that also manage rentals should review IT and cybersecurity for property management, since tenant data adds its own risks.

Small brokerages usually rely on the broker, an office manager, or a tech-savvy agent for IT. That works until a closing goes wrong. A managed IT provider brings monitoring, help desk, and security controls for a predictable monthly fee. When comparing providers, ask whether they have handled business email compromise before, how fast they respond after hours and on weekends (when many closings happen), and whether they can support agents on personal devices. If you already have someone in-house, co-managed IT adds coverage without replacing them. Brokerages west of town can see what local service looks like in our Katy small business IT support article.

This week, turn on multi-factor authentication for every brokerage mailbox and check each one for forwarding rules you did not create. Next, add a wire fraud warning to your client intake documents and email signatures. Then inventory where transaction files live and confirm they are backed up. If you want a partner to carry it, managed IT services cover help desk, device management, and backups, and cybersecurity services add email protection and sign-in monitoring.
