After evaluating dozens of property management companies over the years, the single most important question is how they screen tenants. One bad tenant can easily cost more than years of management fees — and that starts with the screening process.

Credit scores alone are a lazy proxy for tenant quality. What you want to know is whether they look at full rental history, employment stability, income verification, and prior landlord references. The goal isn't the most qualified applicant on paper — it's the tenant most likely to stay for years and treat the property well.

But there's a second question most investors skip that reveals a lot about how transparent the company actually is:

Do you have an in-house maintenance department?

A PM company that profits from repair work on your property has a built-in conflict of interest. More repairs = more revenue for them. That doesn't mean they're dishonest — it means their incentives aren't fully aligned with yours.

What I look for:

• Third-party vendors only, with original invoices provided to the owner
• A defined approval threshold — any repair over a set dollar amount requires owner sign-off before work is ordered
• No percentage-based markups on invoices (a flat coordination fee is fine)

How they answer those two questions — screening and maintenance — tells you a lot of what you need to know before signing.

Curious what questions others have found useful when vetting property managers — especially for those investing in markets you don't live in. What's the one thing you wish you'd asked before signing?
