How to Calculate the DSCR Ratio on a Rental Property (With Real Examples)

Calculate DSCR Ratio

If you’re buying a rental, the DSCR ratio for rental property tells you whether it qualifies for a DSCR loan before you submit an application. Run it before making an offer, and you’ll know where you stand instead of guessing.

DSCR is short for Debt Service Coverage Ratio. It weighs what a rental brings in against what the mortgage costs each month, telling the lender whether the property pays for itself. The math is simple enough to run on a napkin, so you can screen deals quickly.

On Point Home Loans, Inc. works with 200+ lenders across the Charlotte metro and beyond, so we see the full range of thresholds lenders accept. This guide covers the formula, real examples, and what happens when a property falls below the usual targets.

What the DSCR Ratio Actually Measures

The DSCR ratio answers one question: does rental income cover the payment? Because lenders lean on what the property earns rather than the income on your pay stubs, this financing appeals to investors building a portfolio.

The formula:

DSCR = Monthly Rent Collected / Total Monthly Loan Cost

The loan cost side includes principal, interest, taxes, and insurance (PITI), plus HOA if it applies. The rent side is the gross rent the property pulls in monthly.

When the ratio lands at 1.0, the property breaks even. Higher than that, the rent clears the payment with room left over. Under it, the rent falls short, and the difference comes out of your pocket each month.

How Lenders Read the Number

Different lenders set different minimums. Knowing the range helps you target the right deals:

  • 1.25 and above: Strong cash flow. Almost every DSCR lender treats this as a clean approval profile.
  • 1.0 to 1.25: Solid. The property covers itself with some cushion. Most lenders work comfortably here.
  • 0.75 to 1.0: A small monthly shortfall. Fewer lenders accept this, and terms reflect the added risk.
  • Below 0.75: Traditionally the floor for ratio-based loans, though options exist beyond the ratio (below).

No single threshold guarantees approval. Criteria vary by credit, reserves, down payment, and property type. The ratio is one piece, not the whole picture.

Worked Example 1: Single-Family Rental

Let’s run the numbers on a single-family home in the Charlotte metro.

  • Monthly rent: $2,400
  • Principal and interest: $1,500
  • Property taxes: $250
  • Insurance: $100
  • Total monthly debt (PITI): $1,850

DSCR = $2,400 / $1,850 = 1.30

This sits comfortably above 1.25, covering the payment with room to spare. A strong candidate for most DSCR lenders.

Worked Example 2: Duplex

Multi-unit properties combine income from each unit, which often strengthens the ratio.

  • Unit 1 rent: $1,300
  • Unit 2 rent: $1,250
  • Total monthly rent: $2,550
  • Principal and interest: $1,650
  • Property taxes: $300
  • Insurance: $150
  • Total monthly debt (PITI): $2,100

DSCR = $2,550 / $2,100 = 1.21

This duplex lands within the range most lenders accept. Combined rent from both units carries the payment with a modest cushion: a practical, workable deal.

Worked Example 3: Short-Term Rental

Short-term rentals work differently because income swings with the season. Lenders often use a projected or averaged monthly figure rather than a fixed lease amount.

  • Projected average monthly revenue: $3,800
  • Principal and interest: $2,200
  • Property taxes: $400
  • Insurance: $250
  • Total monthly debt (PITI): $2,850

DSCR = $3,800 / $2,850 = 1.33

Strong on paper. One caution: short-term income swings, so lenders may want rental history or a market projection. Conservative investors build in a buffer rather than banking on peak-season figures.

What Happens When the Ratio Comes Up Short

Here’s where many guides stop, but it’s the part that matters most. A low ratio doesn’t end the conversation. Say the numbers don’t quite work:

  • Monthly rent: $1,800
  • Total monthly debt (PITI): $2,000

DSCR = $1,800 / $2,000 = 0.90

This property runs a monthly shortfall, covering 90% of the payment. Some lenders pass on ratios this low, but it’s not your only option.

The no-ratio path. A growing number of lenders offer a no-ratio (no-DSCR) option that skips the ratio entirely. The property still has to make sense, but instead of a minimum ratio, the lender prices the added risk through a larger down payment and stronger reserves. It’s one of several investment property structures worth weighing before walking away.

The trade-off in plain terms:

  • Standard DSCR loan: Lower down payment, but the property needs to hit a minimum ratio.
  • No-ratio loan: No minimum ratio, but expect to put more money down and show more reserves.

This shifts the weight from cash flow to your equity position, keeping a deal alive when the ratio won’t work today. It does not mean little or no money down. The opposite is true: you bring more to the table in exchange for skipping the ratio.

Projecting Your DSCR Before You Make an Offer

Smart investors run these numbers before writing an offer:

  1. Estimate realistic monthly rent from comparable rentals nearby.
  2. Estimate your monthly PITI from the expected loan amount and rate.
  3. Divide rent by PITI for your projected ratio.
  4. Compare against the thresholds above.
  5. If it falls short, ask about no-ratio options before walking away.

Two minutes of math saves you from chasing deals that won’t pencil out or passing on ones that could work another way.

Adjacent Loan Options Investors Ask About

Two other products come up often in investor conversations. Neither is a DSCR loan, but both answer related questions.

Bank statement loans. These qualify the borrower’s personal income from deposit history rather than the property’s cash flow. Rather than asking whether the property pays for itself, this approach looks at your income through bank deposits. Useful for self-employed investors, but qualified on different criteria.

Construction loans. Built around a draw schedule and an interest-only build period, these serve a different purpose than a standard rental purchase. They can now pair with DSCR or bank statement qualification depending on the situation.

Which path fits depends on your deal. A quick conversation sorts out the right structure.

Frequently Asked Questions

What is a good DSCR ratio for a rental property?

A DSCR of 1.25 or higher is strong and qualifies with almost every DSCR lender. Ratios between 1.0 and 1.25 are solid and widely accepted. Below 1.0 means a monthly shortfall, which fewer lenders accept, though no-ratio options exist for properties that don’t hit standard thresholds.

How do you calculate DSCR for a rental property?

Divide monthly rental income by total monthly debt (principal, interest, taxes, insurance, plus HOA if applicable). For example, $2,400 in rent divided by $1,850 in debt equals a DSCR of 1.30. The result tells lenders whether the property’s cash flow covers its mortgage.

Can I get a DSCR loan if my ratio is below 0.75?

Possibly. Although 0.75 has long been a common minimum requirement for DSCR loans, some lenders offer no-ratio programs that don’t rely on a specific DSCR. These loans often require a larger down payment and stronger financial reserves. A low DSCR can make approval more challenging, but it doesn’t automatically disqualify you.

Does a no-ratio loan mean no money down?

No, it means the opposite. A no-ratio loan removes the minimum DSCR requirement, but in exchange, you put more money down and show stronger reserves. The lender shifts the risk from the property’s cash flow to your equity position. Expect a larger down payment, not a smaller one.

What DSCR ratio do lenders require?

Requirements vary widely, from 0.75 to 1.25 and higher depending on the lender, your credit, reserves, and property type. No single threshold guarantees approval. A broker who sees many lenders helps match your property to one whose requirements fit your numbers.
