DSCR (Debt Service Coverage Ratio) is the number commercial property investors have always watched closely. Residential investors have mostly ignored it, because when mortgage rates sat at 2.5% any reasonable property cleared DSCR of 1.0 by default.
That's changed. With mortgage rates above 6%, DSCR separates the investment properties that carry themselves from the ones quietly draining their owners' salaries each month. We calculated DSCR across 12,000+ tracked Australian suburbs at a realistic 6.5% rate and the results sit below.
- At 6.5% mortgage rate with 20% deposit, only suburbs with gross yields above ~5.5% achieve DSCR ≥ 1.0
- Just 15% of Australian suburbs currently meet the DSCR ≥ 1.0 threshold at this rate
- Regional QLD alone accounts for nearly half the DSCR-positive suburbs; Tasmania and regional WA fill most of the rest
- Even "high yield" metro suburbs often fail DSCR - yields of 4.5-5% still leave owners topping up $5K-$10K/year
What DSCR means in residential property
DSCR is the ratio of a property's net operating income to its annual debt service (principal and interest payments). A DSCR of 1.0 means rent exactly covers the loan. Above 1.0, the property pays itself plus surplus. Below 1.0, the owner makes up the difference out of their own pocket.
The formula:
DSCR = (Annual Rent - Operating Expenses) / Annual Mortgage Repayments
For a residential property, "operating expenses" means rates, insurance, property management, maintenance, and strata - typically 1.5-2.5% of property value annually. "Mortgage repayments" means principal and interest at the current rate.
When rates were 2.5%, a $500K property with 4% gross yield carried roughly $10K in annual interest on a $400K loan, easily covered by $20K of rent. DSCR was comfortably above 2.0. At 6.5% rates the same loan costs $26K in interest, and net rent of about $17K no longer covers it. DSCR drops to 0.65. The property itself hasn't changed, only the rate environment around it.
The 6.5% DSCR reality across Australia
We ran DSCR on every suburb in our dataset using standard assumptions:
- 80% loan-to-value ratio
- 6.5% mortgage interest rate
- Operating expenses = 2% of median property value annually
- Annual rent = median weekly rent x 52
| DSCR Range | Suburbs | % of National | What it means |
|---|---|---|---|
| DSCR ≥ 1.5 (strong positive) | 132 | 2.8% | Genuine cash surplus, often regional |
| DSCR 1.0-1.5 (positive) | 573 | 12.2% | Covers loan with small margin |
| DSCR 0.7-1.0 (mild deficit) | 1,487 | 31.7% | Top-up of $2K-$10K/year typical |
| DSCR < 0.7 (significant deficit) | 2,505 | 53.3% | $10K+/year deficit, deep negative gearing |
85% of Australian suburbs currently require ongoing income top-up to hold an investment property at 6.5% rates. Most of those investors bought when rates were sitting near the bottom of the cycle, and the arithmetic has shifted under them.
The top 10 DSCR-positive suburbs
These are the suburbs where the DSCR maths clearly works at current rates, all with DSCR of 1.5 or higher at our 80% LVR assumptions:
| Suburb | State | Median | Yield | Est. DSCR |
|---|---|---|---|---|
| Electra | QLD | $280K | 11.83% | 2.19 |
| Lake Bolac | VIC | $220K | 11.09% | 2.05 |
| Upper Stowport | TAS | $212K | 10.50% | 1.94 |
| Naturaliste | WA | $362K | 11.47% | 2.12 |
| Gundiah | QLD | $310K | 9.90% | 1.83 |
| Roseneath | QLD | $270K | 9.62% | 1.78 |
| Dunnrock | QLD | $383K | 9.49% | 1.75 |
| Boyne Valley | QLD | $300K | 9.57% | 1.77 |
| Waubra | VIC | $230K | 9.60% | 1.78 |
| Kincumber South | NSW | $299K | 11.07% | 2.04 |
Regional Queensland dominates this list, and it's not a coincidence. These are low-price, high-yield micro-markets where rent growth has outpaced price growth over the past three years. The same combination has become rare in capital cities.

At the other end of the distribution, the names are mostly what you'd expect: premium metro postcodes where yields of 2.5% or less leave DSCR in the 0.4-0.6 range. At those levels, the owner is effectively paying half the mortgage out of their own pocket for the lifetime of the hold.
Examples of typical DSCR-negative metro markets:
| Type of market | Typical Gross Yield | Typical DSCR at 6.5% |
|---|---|---|
| Premium Sydney (Eastern Suburbs, North Shore) | 2.0-2.8% | 0.35-0.55 |
| Premium Melbourne (Inner Bayside, Stonnington) | 2.3-3.1% | 0.45-0.60 |
| Inner Brisbane | 3.0-3.8% | 0.55-0.72 |
| Canberra (most suburbs) | 3.8-4.5% | 0.70-0.85 |
| Outer metro Perth | 4.5-5.5% | 0.85-1.05 |
| Regional VIC (e.g. Ballarat, Bendigo) | 4.0-5.0% | 0.75-0.95 |
A DSCR below 1.0 doesn't automatically mean a property is a bad investment. For growth-oriented investors with stable high incomes, carrying a $10K/year loss in exchange for long-term capital gain can make sense. That approach only works if you can sustain the loss indefinitely, capital growth actually arrives, and rates don't rise further. Properties where DSCR is deeply negative (below 0.6) need an especially strong growth thesis to justify holding at all.
How DSCR improves (and what changes it)
A few levers move DSCR, and understanding them shapes strategy.
Interest rate is the biggest lever. DSCR is most sensitive to rate changes - a 1% rate drop (from 6.5% to 5.5%) typically lifts DSCR by 15-18%. If the RBA delivers 3 x 0.25% cuts over the next 18 months (broadly the consensus forecast at time of writing), many suburbs currently at DSCR 0.85 move above 1.0 without any change in property or rent.
Deposit size is the second. Moving from 80% LVR to 50% LVR roughly doubles DSCR on the same property. The obvious trade-off is less leverage and slower portfolio growth, though the flip side is better serviceability and faster refinance flexibility.
Rent growth is the third. Rents rising faster than rates can lift DSCR over a 3-5 year hold. Tight vacancy markets (below 2%) are where this happens. See our glossary entry on vacancy rate for why that matters.
The lever that doesn't help quickly is property price itself. Capital growth reduces LVR over time, which helps future refinances, but it doesn't change current DSCR on an existing loan.
State-by-state DSCR distribution
| State | Median DSCR | % of suburbs DSCR ≥ 1.0 |
|---|---|---|
| TAS | 0.92 | 34% |
| NT | 0.85 | 28% |
| QLD | 0.84 | 24% |
| WA | 0.80 | 22% |
| SA | 0.75 | 15% |
| VIC | 0.72 | 12% |
| ACT | 0.70 | 8% |
| NSW | 0.62 | 7% |
Tasmania comes out on top. Affordable pricing combined with tight rentals gives the state the highest percentage of DSCR-positive suburbs in the country. NT and QLD follow close behind, driven by high-yield regional markets in each. NSW and ACT sit at the bottom, where gross yields are too low for DSCR to work at current rates.
DSCR is a single dimension. It tells you whether a property pays its own way. A high-DSCR property in a suburb with zero population growth is still a losing investment over time. PropRadar's investment score combines DSCR-style cash flow with growth, risk, and market dynamics. A practical approach is to use DSCR as a filter and the investment score as the final ranking.
What to do with this data
Buyers who can't sustain ongoing negative cashflow need DSCR as a hard filter, which means focusing on the 15% of suburbs where the maths works at 6.5% rates. Buyers who can sustain losses and have a strong growth thesis can be more flexible with DSCR, but should still know how far underwater the property will be before committing.
Our rental yield calculator computes DSCR for a specific property, and the suburb finder quiz matches suburbs to your risk profile. For the definitional primer, see our DSCR glossary entry.
DSCR was largely invisible during the low-rate era. It's now the single most important number for anyone buying an Australian investment property. When rent covers the loan, it's investing. When it doesn't, you're subsidising a speculative bet on future growth. Both approaches can work - but they're very different strategies, and they suit very different properties.
Frequently asked questions about DSCR
What is a good DSCR for an investment property in Australia?
DSCR of 1.0 or higher means rent covers the loan and operating expenses. 1.2 or higher gives comfortable margin for vacancy, rate rises, or unexpected expenses. Below 1.0 means you're subsidising the property from salary every month. At 6.5% mortgage rates, only 15% of Australian suburbs achieve DSCR ≥ 1.0 at 80% LVR.
How do I calculate DSCR on a residential property?
DSCR = (Annual Rent - Operating Expenses) / Annual Mortgage Repayments. Operating expenses include rates, insurance, property management, maintenance, and strata - typically 1.5-2.5% of property value annually. Mortgage repayments use principal and interest at the current rate.
What's the difference between DSCR and rental yield?
Yield is rent divided by property price. DSCR is rent (after expenses) divided by loan repayments. DSCR is more useful for investors because it directly answers "can this property pay its own way?" - yield doesn't account for your loan size or interest rate.
Can I improve DSCR without selling the property?
Three main levers: a larger deposit (moving from 80% to 50% LVR roughly doubles DSCR), waiting for rate cuts (each 1% drop typically lifts DSCR by 15-18%), and rent growth (in tight vacancy markets below 2%, rents can outpace rates over a 3-5 year hold). Capital growth itself doesn't help current DSCR until you refinance.
Does negative gearing help DSCR?
No. DSCR is a pre-tax measure. Negative gearing reduces your after-tax loss via a refund at your marginal rate, but it doesn't change the underlying cashflow gap. A property with DSCR of 0.6 still needs you to fund roughly 40% of the loan from salary - negative gearing just makes the sting smaller.
Which Australian states have the best DSCR?
Tasmania leads with 34% of suburbs at DSCR ≥ 1.0, followed by NT (28%) and QLD (24%). NSW (7%) and ACT (8%) sit at the bottom - gross yields in those states are too compressed against current mortgage rates for DSCR to work without a large deposit.
DSCR calculations use 80% LVR and 6.5% interest rate assumptions with 2% annual operating expenses. Individual results will vary by lender, loan structure, tax position, and actual expenses.
