Quick answer
The DSCR ratio is the property’s monthly rent divided by the property’s monthly housing obligation — principal and interest plus property taxes, insurance and any HOA dues. A ratio of 1.00 means the rent exactly covers the obligation; below 1.00 the property does not cover itself at all. Lenders set their own minimum, and the four inputs that move a Georgia file most are the county tax figure, the insurance premium, HOA dues, and the appraiser’s market rent opinion.
The two halves of the fraction
Debt service coverage ratio is a landlord’s version of a simple question: does this property pay for itself? The numerator is the rent the property can command — usually a market rent figure documented by an appraiser, sometimes a signed lease, occasionally a documented short-term rental history. The denominator is the full monthly housing obligation on the loan you are asking for: principal and interest on that loan amount, plus one twelfth of the annual property taxes, plus one twelfth of the annual insurance premium, plus any monthly HOA dues.
Notice what is not in the denominator: your other properties, your personal income, your business revenue. That is the entire appeal of the product for real estate investors. The property is the business, and the lender underwrites the business.
Notice what is also not in the numerator: anything you project. If the property is vacant at closing, the rent figure is an appraiser’s opinion of market rent, documented with comparable rentals. That opinion is the number the lender uses, whether or not your own pro forma is higher.
The worked arithmetic, with dollar figures that are illustrative only
Take a modest Georgia single-family rental renting for $1,900 a month. Annual property taxes on the county’s most recent assessment are $3,400, and a landlord (non-owner-occupied) insurance policy runs $1,750 a year. There is no HOA. Suppose the quoted payment on the loan amount you want comes to $1,840 a month at the rate and term being discussed. The monthly obligation is $1,840 plus $283 of taxes plus $146 of insurance, or $2,269. Divide $1,900 by $2,269 and the ratio is 0.84 — the property does not cover itself.
Those dollar amounts are arithmetic illustration, not a quote, and the payment figure is an input you would enter yourself alongside the rate you are actually offered. Change one variable and the answer changes: at a down payment large enough to bring the payment to $1,310, the obligation falls to $1,739 and the ratio becomes 1.09. Raise the rent opinion to $2,050 and the same loan produces 1.18.
This is why arguing about the ratio in the abstract is wasted effort. The number is a function of four or five inputs, and each one is negotiable in a different way — price, down payment, program, or the evidence you supply to the appraiser.
Four inputs that quietly move a Georgia file
The county tax figure is the input investors most often get wrong. Georgia assesses most property at 40% of fair market value and applies local millage on top, and counties reassess on their own schedules. When a property sells above its last assessed value, the county can move the value. A file modelled on the previous owner’s tax bill may look comfortable and then miss once the new bill arrives. Model the post-closing figure.
Insurance is the second. Age of roof, age of systems, whether the property sits in a designated flood zone, and whether it is coastal all change the premium materially. On coastal Georgia property, a wind and flood premium can be the difference between a deal that covers and a deal that does not.
HOA dues are the third. In the large planned subdivisions of Gwinnett, Cobb, Forsyth and Henry County, dues are a fixed monthly obligation that goes straight into the denominator. Some programs also treat special assessments and mandatory fees differently, which matters if the association has one coming.
The fourth is the rent opinion itself, and it is the one most subject to evidence. A signed lease at a strong number, comparable rentals in the same condition, and a property that photographs as finished all support a higher opinion than a vacant house with a seller’s pro forma attached.
What the bands mean in practice
Investors talk about ratio bands because they are a useful shorthand, provided you remember that the floor is set by the lender and not by the internet. A ratio below 1.00 means the rent does not cover the obligation — the property needs cash from you every month before you count vacancy, maintenance or management. Between roughly 1.00 and 1.20 the property covers itself on paper but leaves very little room for the ordinary cost of owning a building. Between roughly 1.20 and 1.35 there is a working cushion. Above that, the property is doing real work. Where any specific program draws its minimum is set by that lender, and floors differ.
The essential caveat: a ratio of 1.25 is not the same as positive cash flow. Most programs do not deduct vacancy, property management or a maintenance reserve in the coverage test. A property that covers at 1.25 can still lose money every month once a realistic vacancy allowance, a management fee and a maintenance budget are subtracted. The ratio tells you what a lender will accept; your own spreadsheet has to tell you whether you should buy it.
- Below 1.00 — the property does not cover itself. Any approval will require cash from you elsewhere.
- 1.00 to 1.20 — covers on paper with almost no cushion for real ownership costs.
- 1.20 to 1.35 — a working cushion for taxes, insurance and vacancy surprises.
- Above 1.35 — comfortable coverage; useful when taxes or insurance are volatile.
Why the same file gets two different answers
Send one clean file to two wholesale lenders and you can get two different outcomes without changing a single fact. The differences are usually in policy, not in arithmetic: one lender may use a market rent opinion where another will accept a signed lease; one may use the county’s most recent tax figure while another grosses it up; one may require a minimum loan amount that quietly rules out a $140,000 property.
Then there are overlays. Some programs restrict condos with high non-owner-occupied concentration, some limit the number of financed properties an investor may hold, some have added requirements for properties with deferred maintenance. A file that misses one lender by a hair can clear another with the same structure. That is precisely the work a broker does: not finding a magic product, but matching the file to the lender whose policy actually fits it.
What to do when you are short
A coverage shortfall has four honest fixes. Increase the down payment, which lowers the obligation directly and is the most reliable lever. Renegotiate the price, which lowers both the loan amount and, eventually, the tax assessment. Change the property — a different unit count or a submarket with a stronger rent-to-price relationship. Or change the program, which sometimes means accepting a larger reserve requirement or a different structure in exchange for a lower coverage floor.
What does not work is submitting a hopeful application. If the arithmetic does not clear, the appraisal will not save it, and a declined file is a worse outcome than an honest conversation in week one. We would rather tell you the down payment at which a deal clears and let you decide whether that is the trade you want to make.
