Smart investors know that real estate isn’t a passive gamble — it’s a numbers-driven business. But while most owners watch rent, taxes, and appreciation, the top performers monitor a much deeper set of operational metrics that reveal whether a property is maximizing returns or quietly losing money.
Here are the 7 metrics every rental investor should measure — and why they can make or break your portfolio’s performance. 👇
1️⃣ Vacancy & Turnover Cost 💸🚪
The silent cash-flow killer.
Vacancy isn’t “just one month without rent.” It includes:
- Mortgage, taxes, insurance still due 🧾
- Utilities ⚡💧
- Lawn/pool care 🌱
- Repairs + make-ready 🔧
- Cleaning 🧹
- Marketing + showings 📸
- Time lost ⏳
A single turnover can easily cost 1–2 months of rent — making vacancy the largest controllable expense in your real estate business.
How to improve: price right, reduce turnover, and streamline make-ready.
2️⃣ Renewal Rate 🔁🏠
Predictability = power.
A high renewal rate means:
✔ Stable income
✔ Lower turnover costs
✔ Better long-term ROI
A low renewal rate means constant vacancy, repairs, uncertainty, and stress.
Healthy benchmark: 65–75% renewals.
How to boost renewals: clear communication, fair increases, proactive repairs, and a smooth process.
3️⃣ Turnover Time (Make-Ready Days) 🧰⏱️
Every day off-market costs you.
What to watch:
- Days from move-out → completed make-ready
- Days actively listed
- Days until leased
Speed matters — but so does doing it right to avoid tenant issues and rework later.
4️⃣ Days on Market (DOM) 📆📉
Your pricing and marketing reflected in one number.
High DOM often means:
⚠️ Overpricing
⚠️ Weak marketing
⚠️ Poor presentation
⚠️ Slow showing system
⚠️ Needed repairs
Each extra week can eat 1–2% of annual ROI.
Strong target: 7–21 days.
5️⃣ Maintenance Spend as a % of Rent 🔧💵
The most honest maintenance metric.
Instead of asking “How much did I pay?”, ask:
“What percentage of my rental income goes to maintenance?”
Typical ranges:
- Newer homes: 5–8%
- Older homes: 8–15%
- Deferred maintenance: 15%+
The ratio helps you plan, budget, and protect long-term cash flow.
6️⃣ Delinquency Rate 📉💰
Cash flow doesn’t count until it’s collected.
Even one missed payment disrupts performance.
A strong system includes:
✔ Clear expectations
✔ Automated reminders
✔ Multiple payment methods
✔ Quick enforcement
✔ Legal escalation when necessary
Healthy benchmark: under 1% delinquency.
7️⃣ Operating Expense Ratio (OER) 📊🔥
The ultimate profitability test.
OER = Operating Expenses ÷ Operating Income
A low OER = efficient, profitable property
A high OER = cash-flow leak somewhere
Typical SFR range: 30–50%
This is the metric institutional investors live by — and most small landlords don’t calculate at all.
📈 Final Takeaway: Performance Isn’t an Accident
Most investors track rent.
