$300K Cash: Buy Two Properties Fast, or Buy One and Renovate? Here's How to Decide.

This month I got asked the same question maybe fifteen times. Different people, different incomes, different postcodes — but the same core dilemma.

"Joey, I've got $300K-$400K in cash. My income's decent. Should I split my money across two deposits and buy two properties back-to-back, or should I buy one really good property and spend $80K-$100K doing a conversion to lock in positive cash flow before I even think about the next one?"

Fair question. And the answer depends almost entirely on one thing that most people overlook.

The single question that determines your strategy

Do you need negative gearing?

That's it. That's the fork in the road.

If your personal income is above $130,000-$150,000 and you expect it to stay there or go higher over the next two years — and you've got the stomach to be slightly out of pocket each month — then the aggressive two-property approach makes sense. You're buying land, maximising your exposure to capital growth across two different suburbs, and using the tax system to subsidise your holding costs.

If you're more conservative, or you're already carrying debt in other states, or you simply don't want to be feeding money into properties every month — then buying one excellent property and converting it to positive cash flow before moving on is the smarter play.

Neither strategy is wrong. But picking the wrong one for your situation can cost you years 1.

Strategy A: the fast-expansion play (two properties, negative gearing)

This is for the high-income earner who views property as a wealth accumulation engine and is comfortable with short-term negative cash flow in exchange for double the land exposure.

Here's what it looks like in practice with a $350K cash reserve and $150K+ income.

Property 1: $720K in Cranbourne or Hampton Park. 600-square-metre block, weatherboard or single brick, three bedrooms. You put down 20% ($144K) plus stamp duty (roughly $39,600 at 5.5%) plus legal and BA fees. Total cash outlay: approximately $195K. You do a light cosmetic touch-up — $5,000 for paint, maybe $5,000 for SPC flooring — and list it for rent at $520-$560 per week 2.

On an 80% LVR interest-only loan at roughly 6.5%, your annual interest bill is about $37,440. Add council rates ($2,000), land tax ($2,000), insurance ($1,800), PM fees at 4.9% + GST (~$1,550), water ($650), and maintenance ($1,500). Total annual costs: approximately $46,940.

Rental income at $540/week: $28,080. Annual shortfall: roughly $18,860.

But you're on $150K income, sitting in the 37% marginal tax bracket. That $18,860 paper loss — plus depreciation of maybe $8,000-$10,000 on the building — reduces your taxable income by $27,000-$29,000. At 37%, that's approximately $10,000-$10,700 back from the ATO at tax time 3.

Real out-of-pocket after tax refund: about $8,000-$9,000 per year. Or roughly $160 per week.

Property 2: Six to twelve months later, Property 1 has appreciated (Melbourne southeast is running at roughly $5,000-$7,000 per month in 2025). You refinance, extract $30K-$40K of equity tax-free, and combine it with your remaining cash ($155K) to fund Property 2 in a different suburb — say Boronia or Narre Warren.

Same structure. Now you've got 1,200+ square metres of land across two suburbs, double the capital growth exposure, and two negative-gearing deductions stacking on top of each other. Your total annual tax benefit is approaching $20,000. Real cost of holding two properties: maybe $15,000-$18,000 per year combined.

"The whole game is land accumulation," says Joey Don, Co-Founder & CEO at PremiumRea. "You're collecting dirt, and renters are paying most of the bill. The ATO is paying the rest. Each block is appreciating at 7-8% per annum. On $1.4 million of combined property value, that's $98,000-$112,000 of growth per year. Your $18K annual holding cost is nothing next to that."

Strategy B: the steady play (one property, positive cash flow first)

This is for the investor who sleeps better knowing every property they own is self-sustaining. Maybe they're not on a monster salary. Maybe they've been burnt before. Maybe they just reckon there's no point owning something that costs you money every week.

I respect that. And the numbers work differently, but they work.

Property 1: $780K in the outer east or far southeast. 600-plus square metres, good block shape, side access wider than 3 metres. You put down 20% ($156K), stamp duty ($42,900), fees. Total cash outlay: about $210K.

But instead of renting it as-is, you spend $110,000-$125,000 building a 30-square-metre granny flat in the rear yard. That takes 4.5-5.5 months from paperwork to completion 4.

Once the granny flat is done and has its OC, you rent the main house at $500-$550/week and the granny flat at $370-$390/week (including bills). Combined: $870-$940/week.

On the same 80% LVR IO loan at 6.5% on $780K, annual interest is $40,560. Add all holding costs. Total annual costs: approximately $49,000-$50,000.

Rental income at $900/week (midpoint): $46,800.

Net position: roughly -$3,000 per year. Basically break-even. And with one more RBA rate cut (markets expect at least one more in late 2025), you flip to genuinely positive 5.

But here's the bonus. The granny flat doesn't just add rent. It adds value. A $110K granny flat typically lifts bank valuations by approximately $150,000 once the OC is issued 4. You refinance at month 8-10, extract $30K-$50K in equity, and that becomes the deposit for Property 2. Same playbook, different timeline.

The difference from Strategy A? You've never been out of pocket. You've never written the ATO a letter asking for your money back. The property funded itself from the start. It just took a bit longer to get to Property 2.

The Melbourne market in mid-2025: why both strategies work right now

I should note the specific conditions that make both of these strategies viable in 2025.

Melbourne's far southeast is still the affordability sweet spot. You can buy 600-square-metre blocks with habitable houses for $700K-$800K. In Sydney, the same budget gets you a two-bedroom unit in Parramatta with no land, no development potential, and no meaningful capital growth history 6.

The RBA's February 2025 rate cut to 4.10% has already flowed through to improved cash flows. If the cash rate drops to 3.60%-3.85% by early 2026 (as futures markets suggest), every investment property in our portfolio gets a $2,000-$4,000 per year improvement in holding costs 7.

Rents are still climbing. Melbourne's vacancy rate is sitting around 1.5-2.0% in the outer suburbs. We're placing tenants within 14 days of listing, and rents are increasing at roughly 5% per annum. On a $550/week property, that's an extra $27/week next year — $1,400 per year — without doing anything.

And crucially, Melbourne's property market cycle has turned. After three years of falling or flat prices, the growth engine has kicked in. Our internal data shows southeast Melbourne properties appreciating at 7-10% for the 12 months to May 2025 8. Both Strategy A and Strategy B benefit from this. The only question is whether you want to ride the growth wave on one surfboard or two.

Which one did I actually recommend?

Of the fifteen people who asked me this month, here's roughly how it shook out.

Eight went with Strategy A — the fast-expansion play. All had incomes above $140K, stable employment (mostly tech, finance, or healthcare), and existing familiarity with negative gearing from prior investments. Two of them are buying their second Melbourne property; six are entering Melbourne for the first time from Sydney or Brisbane.

Five went with Strategy B. Two were first-time investors with $200K-$250K in savings but no prior property experience. They wanted the emotional comfort of knowing the property pays for itself. Three were experienced investors who already had negatively geared properties in other states and wanted Melbourne to be their cash-flow positive anchor.

Two decided to wait. I told them the same thing I'll tell you: the 70-80 thousand dollar house in Melbourne's southeast is going up by $5,000-$7,000 per month. Waiting six months costs you $30K-$42K in price appreciation. That's not an opinion — it's what the CoreLogic data shows from January to May 2025 8.

But it's their money. The decision has to feel right, not just look right on a spreadsheet.

The one thing I said to all fifteen: whatever you do, buy land. Not a unit. Not a townhouse. Not an off-the-plan apartment in Box Hill. Buy a block of dirt with a house on it — preferably an old one where the land is worth 80% or more of the price. The building depreciates. The land compounds. That's the only rule that never changes.
