how portfolio dscr loans work

A DSCR loan is a special kind of loan for people who own investment properties. DSCR stands for “Debt Service Coverage Ratio”.

The Debt Service Coverage Ratio is a number that shows if you make enough money from your investment properties to pay back the loan.

To get a DSCR loan, you have to show proof that your rental properties make enough income to cover the new loan payment.

Why Do Investors Like DSCR Loans?

Investors like DSCR loans for a few reasons:

  • You don’t have to show personal income or tax returns. The lender only looks at the property’s income.
  • You can get more loans than with a normal mortgage. There’s no limit based on your personal income.
  • It’s easier to qualify if you have lots of properties. Lenders look at all your rental income together.
  • You can tap into your equity and reinvest in more properties.

How is a DSCR Loan Different from a Normal Mortgage?

A DSCR loan is different from a normal mortgage in a few key ways:


With a normal mortgage, you qualify based on your personal income, employment, and credit score.

With a DSCR loan, you qualify entirely based on the property’s projected net operating income. Your personal finances don’t matter.

Credit Score

Your credit score is very important for qualifying for a normal mortgage.

With a DSCR loan, your credit score is less important. The focus is on property cash flow.

Debt-to-Income Ratio

For a normal mortgage, your total personal debt compared to income (DTI) must be under 50%.

With DSCR loans, your personal DTI doesn’t matter because qualifying is based on property income.


To get a normal mortgage, you need tax returns, bank statements, and pay stubs.

DSCR loans require much less documentation. You just need to show property income and expenses.

What is the DSCR Formula?

Lenders use this formula to calculate the DSCR:

Net Operating Income / Annual Debt Service = DSCR

Net Operating Income (NOI)

NOI is the annual rental income minus all operating expenses and vacancies.

NOI doesn’t include mortgage payments. It’s the money left over after operating costs.

Annual Debt Service

The annual debt service is the total mortgage payment due each year – principal plus interest.

Debt Service Coverage Ratio

Divide NOI by the proposed annual debt to get the DSCR.

For example:

  • Rental Income: $60,000
  • Operating Expenses: $15,000
  • NOI = $60,000 – $15,000 = $45,000
  • New Mortgage Payment: $30,000/year
  • DSCR = $45,000 / $30,000 = 1.5

This property has a DSCR of 1.5, meaning there is enough income to cover the new mortgage payment.

What DSCR Do Lenders Look For?

Most lenders want to see a minimum DSCR of 1.20 or higher.

  • DSCR of 1.20 – This means the NOI is 20% more than the annual debt service. There is enough cushion to make the payments.
  • DSCR below 1 – This means negative cash flow. The property does not make enough to cover the loan payment. Lenders will not approve.
  • DSCR of 1.5 or higher – This is considered an excellent ratio by lenders for an investment property. It means very low risk.

Each lender has their own DSCR requirements. A higher DSCR gives more wiggle room in case income decreases.

Who Offers DSCR Loans?

Many types of lenders offer DSCR loans:

  • Banks – Large banks are often willing to do DSCR loans for experienced real estate investors with strong portfolios.
  • Credit Unions – Some credit unions offer portfolio lending programs with flexible DSCR options.
  • Mortgage Companies – Many national mortgage lenders have DSCR loan programs.
  • Private Lenders – Hard money and private lenders commonly use DSCR for real estate loans. Rates may be higher.
  • Portfolio Lenders – Banks that keep loans in their portfolio instead of selling them. They can create custom DSCR loans.

What Properties Qualify for a DSCR Loan?

DSCR loans work best on stable, performing investment properties like:

  • Apartment buildings
  • Retail centers
  • Office buildings
  • Industrial complexes
  • Self storage units
  • Manufactured home parks
  • Assisted living facilities

Lenders want to see at least two years of solid operating history. Vacancy rates should be low and operating income steady.

They usually don’t offer DSCR loans on non-income producing properties like:

  • Vacant land
  • Owner-occupied homes
  • Fixer-uppers

But some lenders may consider these on a case-by-case basis.

How Much Can You Borrow with a DSCR Loan?

With a DSCR loan, the amount you can borrow depends on the property’s NOI, not your personal income.

For example:

  • Property NOI: $100,000
  • Minimum DSCR: 1.25

$100,000 / 1.25 = $80,000 maximum annual debt service

If the interest rate is 5% on a 30-year loan, the maximum loan amount would be around $1.5 million.

A higher DSCR requirement would mean a lower maximum loan amount.

Many lenders will loan 65% to 80% of a property’s value with a DSCR loan. So maximum LTVs are often 70% to 85%.

What is the Rate and Term for a DSCR Loan?

DSCR loan rates and terms depend on several factors:

Interest Rate

  • DSCR loans typically have higher rates than owner-occupied loans.
  • Interest rates usually range from 6% to 9% for commercial properties.
  • Better property profiles can qualify for lower rates.

Loan Term

  • Terms are often 5, 7, 10, 15, 20, or 30 years.
  • 10- and 15-year loans are common for DSCR borrowing.
  • Amortized over 20+ years, but with a shorter maturity.
  • Balloon payment required at maturity.

Always compare loan quotes from multiple lenders. Shop around for the best DSCR rate and terms.

DSCR Loans for Purchasing Investment Property

The DSCR formula makes it possible to buy income property even if you don’t qualify for a normal mortgage.

For example:

  • Duplex Purchase Price: $400,000
  • Duplex Rental Income: $36,000/year
  • Total Expenses: $10,000/year
  • NOI = $36,000 – $10,000 = $26,000

With a 75% LTV and 5% rate, the payment would be around $26,000/year.

$26,000/$26,000 = DSCR of 1.0

This meets the minimum DSCR, so you may qualify for the purchase. Your personal finances don’t matter.

Using DSCR Loans for Refinancing

Refinancing with a DSCR loan lets investors cash out equity while keeping payments affordable.

For example, you may have a property with 50% equity, but the rent rolls don’t support a large payment.

A DSCR refinance could let you pull cash out of the property while keeping the payment the same.

This strategy needs to make sense based on your entire real estate portfolio and goals.

Benefits of Using DSCR Loans

DSCR loans offer many perks for real estate investors:

  • Purchase More Properties – Your buying power isn’t limited by personal income or credit.
  • Tap into Your Equity – Refinance to pull cash out while keeping payments affordable.
  • Consolidate Properties – Combine multiple loans into one convenient DSCR loan.
  • Buy and Hold Long Term – Loans are typically interest-only or have long amortizations.
  • Use Commercial Properties – DSCR works for apartment buildings and retail centers.
  • ** Minimal Documentation** – You don’t need to provide tons of financial records.
  • Build Your Portfolio – Use cash-out to purchase additional income properties.

Risks Associated with DSCR Loans

While DSCR loans offer more flexibility, they also come with some risks:

  • Property Vacancies – Significant vacancies will reduce NOI and DSCR.
  • Interest Rate Changes – Your DSCR could fall if loan rates rise at renewal.
  • Balloon Payments – You’ll need to refinance or pay off the balance when due.
  • Tighter Requirements – Lenders may impose stricter terms over the life of the loan.
  • Prepayment Penalties – Refinancing too soon may incur extra fees.
  • Lower Equity – Cash-out refinancing reduces your ownership and equity.

Be cautious when relying heavily on DSCR leverage to grow your portfolio. Market changes can impact your property cash flows.

Is a DSCR Loan Right for You?

Ask yourself these questions to decide if a DSCR loan fits your investment strategy:

  • Do you have a solid history as a real estate investor? Lenders prefer experience.
  • Do you own properties producing steady rental income? Vacancies will hurt your DSCR.
  • Are your properties professionally managed? This optimizes cash flow.
  • Can you cover costs if you have vacancies? DSCR depends on full occupancy.
  • Are you comfortable with higher leverage? DSCR loans maximize your borrowing capacity.
  • Can you manage balloon payments down the road? There is refinance risk.

DSCR loans work best for experienced investors with a stable portfolio of income properties. If used strategically, they provide access to financing that would otherwise be out of reach. But they require careful financial planning to manage cash flows and mitigate risk.
