The Dreaded Debt-To-Income Ratio

This past week, I met with a 35-year-old real estate investor who had two rental properties under their belt and wanted to know how they could accumulate more properties without crushing their debt-to-income ratio to the point they would not be able to qualify for another mortgage.

For those folks not familiar with this term, the debt-to-income ratio (DTI for short) is a calculation a lender will use to see if you have too much debt.It is good to know what your particular number is and to know whether it is considered in the good range or if it is in the danger zone.

Simply stated, your DTI is the percentage of your income needed to cover your loan payments.In other words, for every dollar of income, how many cents are eaten up with debt payments?If a person has $2,000 per month going out in debt payments (mortgage, car note, credit cards, student loans, etc.) and their gross monthly income (before taxes and deductions) was $6,000 then this person’s DTI would be 33% (2,000 divided by 6,000 = .33).

Most lenders have internal guidelines for what they want this ratio not to exceed.Some lenders will even split that figure into two.They want to know how much of a person’s income is needed solely to pay their mortgage debt (typically, lenders want to see this below 33%) and a second calculation used to see how much total debt a person (or couple) has relative to their income.The maximum total DTI for a lot of lenders is 43%.They do not think it would be prudent for a borrower to have more than 43 cents of every dollar a person earns going to pay debt since the higher this number is, the greater the probability for a person to get into financial problems and default on their loan payments.

Here is the problem with this calculation.It does not work well for a person who wants to accumulate a lot of assets by investing in multiple rental properties.Each lender can arbitrarily apply different rules to different sets of circumstances.For example, it someone is going to buy a house to fix up and eventually rent out for income, a lender may decide not to include the income from this new property until it shows up on a tax return.

If you buy a house in January, this would mean the income from this house will not show up until around April 15th the following year which is 15 months later!But here is the kicker:the lender WILL count the debt against you on the calculation of the ratio.It is clear to see the implication of counting 100% of the debt with 0% of the income as it will hamper your ability to do very many of these transactions, depending on how high your personal income is.

The DTI ratio is applied mostly to folks with jobs that use debt to finance their personal residence, their personal car, and their personal consumption for bigger ticket items.In short, this is consumer debt used to purchase liabilities. Liabilities, you may recall, are made up of stuff that takes money out of your pocket every month like this type of debt is designed to do.

However, if you want to break free from having this calculation used against you which will severely limit the number of properties you will be able to purchase, then you need to utilize a different strategy.

Instead of using a mortgage banker who typically finance owner-occupied residential properties which are a liability, you need to cultivate a relationship with a bona-fide professional commercial banker.These people are much fewer in number than mortgage bankers and they are in the business of financing the purchase of income producing assets.

A commercial banker will look at the property you want to purchase and will use the income generated by the property to calculate a Debt Service Coverage ratio (DSC for short).Instead of the DTI, the lender will want to know the DSC which is made up of the following:

Gross rental income minus property taxes and insurance minus repairs and maintenance = Net Operating Income (NOI).Then they will divide the NOI by the monthly principal and interest payment to get a DSC ratio which should be higher than 1.25.In other words, the asset (rental property) is generating $1.25 of cash (NOI) for every $1 of debt payments.

Let’s input some real numbers.If a property generates $1,650 per month in rent and, after the expenses listed above the NOI is $1,431.Assume a monthly payment of $516 for principal and interest would equate to a 2.77 DCR (1,431 divided by 516 = 2.77).

This is how real estate investors can accumulate a larger number of properties than a typical individual that hits the proverbial brick wall and cannot finance anymore due to going to the wrong type of lender (mortgage lender which uses the DTI ratio) instead of using the right lender (commercial banker which uses the DSC ratio).

If you want to grow your wealth and own multiple properties either as an individual or a team, then you have just learned a very important distinction that will get you there much quicker!

  1. Wasted a year or two just because i didnt know how to tackle with DTI. THANKS A TON.


  2. This is probably one of the most informative posts I have read about how to go about growing my portfolio.

    I also did not know about DSC.

    I have been doing hard research to find out how to do a BRRRR  with DTI while My spouse is Self Employed, and we already have 2 properties with a Private Lender but want to expand our Investments.

    I know this is an older post but it needs to be re posted and kept up with any change that might have occurred. Thank you David Vernich for taking the time to write about this topic.  


  3. Yes I can give you tips on finding a commercial lender and no, this type of lender does not offer 30 year fixed rate loans.  Thirty year fixed mortgages are offered through numerous mortgage brokers in your area for a loan that will be in your personal name and there is a maximum limit on these type of loans (limited by your W-2 income and the maximum number of loans they will allow one borrower to have).

    The best way to find a commercial banker is to network with other RE investors in your area and ask them who they use and (this next point is very important) would they make an introduction to their banker for you.  The reason being, unless you don't know a soul in your area, it is far better to be introduced to a commercial lender by another RE investor, CPA, or business owner than to walk in cold off the street.  Your reception will be much better the way I recommend you find a good lender versus taking the pot luck approach and trying to find the needle in a haystack by yourself.  Hope that helps!


  4. this was a very helpful article thank you. Could you offer any pointers to finding these commercial lenders, and will they do 30 year fixed rate loans?


  5. A standard figure for R&M is hard to pin down.  Some people use a flat dollar amount per month per unit.  When you have enough history, you can also take the historical average (at least you have something to justify to the banker) of actual R&M expenses since it is hard to argue with actual numbers.

    My personal experience has been that this has been all over the board with some banks injecting their standard formula as a percentage of gross rents and others that don't put in anything at all, especially if they are using historical numbers from tax returns to calculate the Debt Service Coverage.

    As a fellow RE investor, my response to my bankers is:  "I just spent a ton of money fixing up the place and we did a great job!  We shouldn't have any major R&M expenses for the first several years!" and that has worked, believe it or not.

    The point of the Debt Service Coverage ratio is to know ahead of time how the properties cash flow in relation to the proposed debt and your job, as a RE investor, is to know what that number is and to have a response to the banker if they throw a curve ball at you for how you plan to cover R&M expenses, etc.  Hope that helps some?


  6. Great breakdown, but one question.  When you state NOI = Gross Rent - (Taxes+Insurance+Repairs & Maintenance) what are you using for R&M?  A factor or based on some measure of performance?  Clarity here would help my calculations.

    Side note, I've also had residential bankers tell me they don't count rental income until 2-years of ownership.  Banks are afforded some latitude on what qualifies as seasoned, but you're right that it takes at a minimum a tax return.  Great post!


  7. Great post David!  One thing I'd like to note though is that while working with commercial lenders is much more based on the asset (rather than an individual's DTI), there are downsides associated with commercial loans.  I've had several commercial lenders tell me before "Unless you absolutely need a commercial loan, you want to max out the number of residential loans first and then shift to commercial."  Commercial lenders simply don't offer 30YR fixed rate loans like a regular bank does.  Usually the maximum length of a loan would be 20 years (rarely, 25 if you can do some negotiating), and the rates are almost never fixed for more than 5 year periods.  I've also seen the rates for commercial loans anywhere from half a point to a point-and-a-half higher than a similarly-sized residential loan.

    Now I'm not trying to knock down commercial loans.  They're very helpful, and of course, are always used on multifamilies with 5+ units.  Its just important for a new investor to not rush out there and try and qualify for a commercial loan on their four-family, when they could get a lower rate and more attractive terms talking to a residential lender instead so long as they qualify with an appropriate DTI ratio.    


    1. I totally agree with you to max out on the number of loans you can get with a 30 year fixed rate first.  Some deals won't cash flow on a 20 year amortization depending on your market and the price you end up having to pay for the purchase and renovation versus the rental income it can generate.   I see a ton of newbies hit the wall on financing when they either max out their limit on the number of loans (or dollar amount they can qualify for) and wonder how they are going to build a large rental portfolio without Fannie/Freddie financing.  The answer is, pivot to your local community banks and credit unions that will finance permanent loans on rental properties and keep going!


  8. Thanks David,

    Nice narrative in simplying things. 

    I did  calculations of my rentals, Now  I know  where to focus next time.


  9. Glad you found it helpful.  Many new investors struggle to understand how they can accumulate more than a few properties when Fannie and Freddie limit how many a person can purchase.  This is how you can break through this barrier but it is important to cultivate a relationship with a commercial lender at a bank or credit union in your area so you can achieve a higher number of rentals.


  10. David,

    Great article! I had no idea that DSC even existed. I'm very new to real estate investing and while my wife and I make respectable salaries this could potentially unlock another level of possibilities for us that will enable us to achieve our goals and begin our calling! Thanks again.
