How should I review a property management firm’s maintenance vendor relationships?

Ask for a list of every maintenance vendor with the work they do, how they are paid and who approves their invoices. Check which relationships are written down and which are handshakes. Then ask a few vendors whether they plan to keep working with the firm after a sale.

Build a vendor table: trade, name, how long they have worked with the firm, rates, payment terms and the buildings served. Look for gaps. If one plumber or one electrician handles most calls, the firm depends heavily on that person. Ask what happens when they are unavailable.

Study the money flow. Vendors often bill the firm, which then charges owners, or bill owners directly. Ask who pays first, how fast owners reimburse and whether the firm ever carries unpaid vendor invoices. Late payments strain relationships and can show up as service problems. Also find out whether any vendor offers the firm special rates that may not carry to you.

Look at quality and compliance. Ask how vendors are chosen, how work is checked, how tenant complaints are logged and what happens after a bad job. Ask whether insurance and credentials are collected from each one, and how often they are checked. Look for conflicts too. Is any vendor owned by the seller or a relative? That is not necessarily wrong, but you should know. Finally, speak to the key vendors with the seller’s consent. Their willingness to continue is better evidence than any list.

Key takeaways

  • Tabulate vendors by trade, tenure, rates and buildings served.
  • Check payment flow and whether the firm carries unpaid vendor invoices.
  • Ask about related-party vendors and speak to the main ones directly.
  • Keep the related-party question open until the seller answers it in writing.
