With a $300k deposit, you can enter property investment and build wealth through leverage. This guide shows your options, financing paths, and 5-year wealth projection.
What Can You Buy With $300k Deposit?
Assuming 20% deposit ratio (conservative, no LMI):
Maximum purchase price: $1.5M
Your Options in Inner-North:
| Property Type | Suburb | Median Price | Deposit (20%) | Loan Amount | Yield |
|---|---|---|---|---|---|
| Unit | Preston | $524k | $105k | $419k | 5.1% |
| Unit | Northcote | $600k | $120k | $480k | 5.1% |
| House | Thornbury | $1.39M | $278k | $1.112M | 4.7% |
| House | Coburg | $1.21M | $242k | $968k | 4.6% |
Strategy 1: Single High-Yield Unit (Conservative)
Buy 1 unit, keep $195k in reserve.
Example: Preston Unit, $524k
- Deposit: $105k
- Loan: $419k @ 7% = $29.3k/year interest
- Weekly rent: $420 = $21.84k/year
- Less expenses: $8k/year (rates $3k, insurance $1.5k, PM $2.5k, maintenance $1k)
- Net income: $13.84k/year
- After mortgage: $13.84k – $29.3k = -$15.46k/year (NEGATIVE)
- BUT: Mortgage principal reduction ~$3k/year reduces true loss to -$12.46k
Verdict: Negative cash flow, but excellent capital growth play. If property appreciates 3% = $15.7k/year gain.
5-year outlook: Property $524k → $610k (+$86k), loan $419k → $380k, equity $105k → $230k.
Strategy 2: Two Units (Yield Focus)
Buy 2 high-yield units across suburbs.
Example: Preston Unit + Northcote Unit
- Property 1 (Preston): $524k, deposit $105k, loan $419k
- Property 2 (Northcote): $600k, deposit $120k, loan $480k
- Total capital deployed: $225k (of $300k)
- Reserve: $75k
Combined financials:
- Total rent: $420 + $475 = $895/week = $46.5k/year
- Total expenses: $16k/year
- Net income: $30.5k/year
- Total mortgage: $899k @ 7% = $62.9k/year interest
- After mortgage: $30.5k – $62.9k = -$32.4k/year
- Principal reduction: ~$6k/year
- True loss: -$26.4k/year
BUT: Capital appreciation. If properties appreciate 2% = $22.5k/year combined gain. Combined gain + appreciation ≈ break-even.
5-year outlook: Portfolio $1.124M → $1.28M (+$156k), loans $899k → $825k, equity $225k → $455k.
Strategy 3: Deposit + Equity (More Leverage)
Use $300k deposit + borrow against primary residence equity.
Scenario: You own home worth $1M, $200k equity available via HELOC.
Total capital: $300k + $200k = $500k → Can buy $2.5M property (at 20% deposit).**
Example: Coburg House $1.2M + Thornbury House $1.3M
- Property 1: $1.2M, 20% deposit = $240k
- Property 2: $1.3M, 20% deposit = $260k
- Total deposit: $500k ✓
- Total loans: $1.96M @ 7% = $137.2k/year interest
- Total rent: $430 + $450 = $880/week = $45.8k/year
- Net income after expenses: $30k/year
- After interest: $30k – $137.2k = -$107.2k/year (VERY NEGATIVE)
Verdict: RISKY. Only do this if you have $100k+ annual income to cover negative cash flow.

- Path: Clear — buy 1, hold, buy 2, scale
Common $300k Mistakes
Mistake 1: Overextending With LMI
Problem: Use 10% deposit, pay $40k LMI, stretch to buy $2M property. Loan $1.8M @ 7% = $126k/year interest. Rent $1.8M property = $65k/year. Loss = $61k/year (unsustainable).
Fix: Start conservative (20% deposit, 1 property). Once cash flow stable, expand leverage.
Mistake 2: Not Keeping Reserve
Problem: Deploy all $300k into deposits. Then vacancy/repair hits, can’t cover mortgage payment.
Fix: Keep $50–100k in offset/emergency account. Invest remaining $200–250k.
Mistake 3: Wrong Suburb Choice
Problem: Buy in lower-yield suburb (Ivanhoe 3.8%) instead of high-yield (Preston 5.1%). 1.3% difference = $6.8k/year less income on $524k property.
Fix: Prioritize yield for cash flow (Preston, Northcote, Coburg). Prioritize growth for appreciation play (Ivanhoe, Kew, Richmond).
FAQs: $300k Investment Deposit
Q: Can I use $300k to buy a house?
A: Yes, but risky. $300k = 25% deposit on $1.2M house (good LVR). BUT: Houses have higher maintenance costs, longer holding periods. Unit is safer (5–10 years to build wealth). House is better for 15+ year holds.
Q: Should I buy 1 or 2 properties?
A: Buy 1 first. Understand cash flow, maintenance, tenant management with 1 property. Then buy #2 once confident. This is the safe path to a 10-property portfolio.
Q: How long until I’m cash flow positive?
A: 5–10 years depending on interest rates. As mortgage principal decreases, cash flow improves. At year 10, your $419k loan is ~$350k, and rent rises 2–3%/year. Breakeven is realistic by year 8–10.
Your $300k Action Plan
- Save emergency fund: $50k (in offset account, offset mortgage interest)
- Invest capital: $250k into 1 unit purchase
- Hold & stabilize: 3 years (understand property investing)
- Refinance: Borrow against equity, or save for property #2 deposit
- Scale: Buy property #2 (year 3–4)
- Compound: By year 10, you have $1.5M+ portfolio, $500k+ equity
