What Metrics Should a BDM Track? 4 Numbers That Drive Real Rent Roll Growth

Being a busy BDM doesn’t automatically mean you’re being effective.

You can book back-to-back appraisals, nail your listing presentation, and still not see your rent roll growth move the way it should. And that’s often because the right numbers aren’t being tracked… or worse, no numbers are being tracked at all.

If you’re serious about growing your portfolio, improving your pitch, and having the kind of conversations with your Director that actually mean something, you’ve got to get clear on these four BDM performance metrics.

They’re simple. They’re powerful. And they’ll show you exactly where to focus for real growth.

1. Your Conversion Rate from Lead to Appraisal AND Appraisal to Lead

This is where we double down. Because tracking just one part of the journey isn’t enough.

First, you want to know how many leads actually book an appraisal with you. Then, from there, how many of those appraisals turn into signed managements? Two key conversion points. Both matter. Both tell a story.

What to track:

• Leads generated
• Appraisals conducted
• New managements signed
  

How to calculate:

• Lead to Appraisal: Appraisals ÷ Leads × 100
• Appraisal to Management: Managements ÷ Appraisals × 100

👉 Example:

• 20 leads results in 10 appraisals = 50% (Lead to Appraisal)
• 10 appraisals results in 4 managements = 40% (Appraisal to Management)
• 20 leads results in 4 managements = 20% (Lead to Management – overall conversion)

This calculation can show you where you’re losing momentum. Are leads going cold before the appraisal? Is your pitch not landing when you’re in the room?

My extra tip:
Break it down by lead source. Cold calls, digital leads, sales team handovers. Each will convert differently. That’s your goldmine for insight on what to focus on.

2. % Increase in Annualised Management Fees

So many BDMs obsess over how many new properties they’ve signed. But for your director, 10 new managements might mean nothing if they’re all low-fee or high-risk.

This metric tells you whether you’re actually growing the value of the rent roll.

How to calculate:
Compare your total annualised management fee value (weekly fee x 52) over time.

👉 Example: If you start the year at $480,000 and now sit at $528,000 in annualised fees, that’s a 10% increase.

This is how you measure true business growth. Not just in numbers, but in revenue. And if you’re signing higher-quality properties, or increasing your average fee per door, you’ll see it here.

My extra tip:
Keep an eye on your fee structures. If you’re discounting just to win business, this number will let you know the real cost.

3. Net Rent Roll % Growth (Including Losses)

Gross growth tells half the story.
If you signed 15 properties this month but your property management department lost 12? That’s a revolving door.

Tracking your net rent roll growth as a percentage (including losses) gives you the real picture.

What to measure:

• Managements gained
• Managements lost
• Reason for each loss
• Net growth (gains – losses)

How to calculate:
(Net gain ÷ starting total) x 100 = % growth

👉 Example: You gained 12, lost 4, and started with 400?
That’s a 2% net growth.

This one’s essential for Directors too. It shows how stable the business is and helps with forecasting revenue. If you’re bleeding properties out the back door, it’ll show up here fast.

Just remember that losing properties is normal. But if you’re not tracking why, you’re missing a massive opportunity to tighten your service or shift your strategy.

4. Annualised Fee Growth in Dollars ($)

This is where the numbers get real. It’s not about how many properties you signed, it’s about how much revenue you added to the business.

What to track:

• Annualised fee value of all new managements (weekly fee x 52)
• Minus any lost fee value from exits or terminations

👉 Example:
You signed 5 properties this month at $80 per week in management fees:
5 x $80 x 52 = $20,800 in new annualised revenue.

If you lost $4,000 in fees that month, your net fee growth is $16,800.

This number doesn’t lie. It’s what Directors care about, it’s what justifies resourcing, and it’s what shows whether your growth is financially healthy.

My extra tip:
Use this number in your monthly wrap-up reports. It shows your impact better than a property count ever could.

You don’t need a spreadsheet for every step you take as a BDM, but you do need clarity on what actually drives your results.

These four BDM performance metrics give you:

• Evidence of your impact
• Direction for where to improve
• Language to lead stronger convos with your team

And most importantly? They keep you focused on real growth, not just activity for activity’s sake.
