Michigan offers a range of rental markets, from high-yield single-family homes in Detroit to short-term vacation rentals on the Lake Michigan shoreline. DSCR loans (Debt Service Coverage Ratio loans) are one of the most practical financing tools for investors operating in these markets, because approval hinges on what the property earns, not what the borrower reports on a W-2.
What a DSCR Loan Actually Measures
A DSCR loan qualifies a borrower based on the income a rental property generates relative to its debt obligations. The core formula is straightforward:
DSCR = Net Operating Income / Annual Debt Service
Net Operating Income (NOI) is the gross rental income minus operating expenses such as property management fees, insurance, and taxes. Annual debt service is the total principal and interest due over 12 months.
A DSCR of 1.0 means the property's income exactly covers the mortgage payment. Most Michigan lenders want to see a ratio of 1.1 to 1.25 or higher. Some lenders will accept a ratio below 1.0, which signals negative cash flow, but those loans typically carry higher rates and stricter LTV (loan-to-value) caps to offset the risk.
Example: A Grand Rapids duplex generates $2,400 per month in rent ($28,800 annually). After expenses, NOI is $22,000. If the annual debt service on the proposed loan is $19,500, the DSCR is 1.13. Most conventional DSCR lenders would approve that scenario.
Michigan DSCR Loan Requirements
Requirements vary by lender, but the following ranges reflect what most DSCR lenders operating in Michigan apply as of 2024:
- Minimum DSCR: 1.0 to 1.25 depending on lender; sub-1.0 products exist but carry rate premiums of 0.5 to 1.0 percentage points
