How to Calculate DSCR for Multi-Family Properties

When investors evaluate rental properties, one of the most important numbers to understand is the debt service coverage ratio, commonly referred to as DSCR.

This ratio compares the rental income produced by a property to the mortgage payment required to finance it.

Because DSCR loans focus on the income generated by the property, lenders use this calculation to determine whether the property produces enough income to support the loan.

Understanding how DSCR is calculated allows investors to evaluate potential deals before submitting an offer.

DSCR calculations are commonly used when financing multi-family properties with several rental units, including properties with 5 to 8 units.

For a broader overview of financing options for these properties, see DSCR Loans for 5 to 8 Unit Multi-Family Properties.

 

What DSCR Means

DSCR stands for debt service coverage ratio.

The ratio measures how the income generated by a property compares to the mortgage payment required to finance the property.

Lenders use this calculation to determine whether the property generates enough income to support the loan payment.

If the property produces sufficient rental income, it may qualify for DSCR financing.

Many DSCR loan programs allow a minimum DSCR ratio of approximately 1.00.

This means the rental income must at least equal the monthly mortgage payment.

 

DSCR Formula

The DSCR formula is straightforward.

Monthly rental income ÷ Monthly mortgage payment

The mortgage payment typically includes:

Principal
Interest
Property taxes
Insurance

In some cases, lenders may also include association dues if they apply to the property.

The result of this calculation produces the DSCR ratio used in underwriting.

 

Example DSCR Calculation

Consider a multi-family property with 6 rental units.

If each unit rents for $1,600 per month, the total monthly rental income would be

$9,600 per month

If the total monthly mortgage payment for the property is $8,500, the DSCR calculation would be

$9,600 ÷ $8,500 = 1.13

In this example, the property produces a DSCR ratio of 1.13.

Because the rental income exceeds the mortgage payment, the property generates enough income to support the loan.

 

What DSCR Ratios Mean

Understanding what different DSCR ratios represent can help investors evaluate deals more effectively.

DSCR below 1.00

The property does not generate enough rental income to cover the mortgage payment.

DSCR equal to 1.00

The rental income exactly covers the mortgage payment.

DSCR above 1.00

The property generates more rental income than the mortgage payment and produces positive cash flow.

Many lenders offering DSCR loans for multi-family properties require a minimum ratio around 1.00.

 

How Lenders Calculate Rental Income

Although the DSCR formula itself is simple, lenders carefully evaluate how rental income is calculated.

Rental income is typically verified using:

• Current leases
• A rent roll showing each unit and rental amount
• Market rent estimates from the appraisal

For leased units lenders generally use the lower of the lease amount or the market rent determined in the appraisal

Vacant units are often counted at approximately 75 percent of market rent.

Investors evaluating properties with vacant units should review How Vacancies Affect DSCR Loan Qualification.

 

Why Investors Calculate DSCR Before Making an Offer

Many investors calculate DSCR before submitting an offer on a multi-family property.

By estimating rental income and loan payments early in the process, investors can determine whether the property is likely to qualify for DSCR financing.

This type of analysis also helps investors understand how sensitive a deal may be to changes in rent or financing terms.

For example, a property with a DSCR of 1.20 may have more flexibility if rents decline slightly or expenses increase. A property with a DSCR close to 1.00 leaves less margin for changes in income or expenses.

Because of this, DSCR calculations are often used as part of the early screening process when investors compare potential acquisitions.

 

How DSCR Influences Financing

The DSCR ratio can affect several aspects of a loan including:

Loan approval
Maximum loan amount
Down payment requirements
Interest rate pricing

Properties producing stronger rental income relative to their mortgage payments may qualify for higher loan amounts.

If a property’s rental income is close to the minimum requirement, the lender may reduce the loan amount or require a larger down payment.
