Every real estate investor asks the same question: What’s a good ROI on rental property?

The problem is that most answers online are oversimplified. You’ll see percentages thrown around—8%, 10%, 12%—but without context, those numbers are meaningless.

A “good” return depends on location, risk, asset class, operating structure, financing, and management efficiency. A poorly managed high-ROI property can underperform a well-managed moderate-ROI asset over time.

At JMZ Management, we look at ROI as a performance system, not a single number. True rental investment success comes from combining strong cash flow, operational efficiency, asset protection, and long-term value growth.

Setting the right rent is one of the most important decisions a landlord makes—but it’s also one of the easiest places to go wrong. In a market like Detroit, rental pricing isn’t "one-size-fits-all." Neighborhood conditions, tenant demand, seasonality, and local trends all play a role. When pricing is off, it can lead to longer vacancies, reduced cash flow, or avoidable tenant turnover.

Here are the most common Detroit rental pricing mistakes landlords make—and how to avoid them.

Before welcoming a new tenant, every landlord and property manager faces the same question: Is the property truly ready for move-in?

A make-ready checklist provides that answer. It’s a structured guide used to ensure a rental property is thoroughly cleaned, inspected, repaired, and compliant with safety standards before new tenants arrive. This checklist helps landlords protect their investment, maintain tenant satisfaction, and reduce costly turnover delays.
