$300k Deposit Property Investment Strategy

June 17, 2026

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.

Financing Options for $300k Investor

Option 1: Personal Loan (20% deposit, no LMI)

  • Deposit: $105–120k (20%)
  • Loan: $419–480k (80%)
  • LMI: $0 (avoided)
  • Interest rate: 6.9–7.2%
  • Term: 30 years

Option 2: LMI Loan (10–15% deposit, pay LMI)

  • Deposit: $52–78k (10–15%)
  • Loan: $446–472k (85–90%)
  • LMI: $25–40k (added to loan)
  • Total loan: $471–512k
  • Interest rate: 7.3–7.7% (slightly higher)
  • Term: 30 years
  • Advantage: Stretches $300k to buy 2 properties ($1.0M+)

Option 3: HELOC + Personal Loan (Leverage home equity)

  • HELOC on primary residence: $150–200k @ 7.5%
  • Personal loan: $100–150k @ 7.2%
  • Combined: $250–350k capital to invest
  • Advantage: More capital deployed, faster compound growth
  • Risk: If income drops, can’t service both mortgages

5-Year Summary:

  • Started: $300k capital
  • Ended: $317k equity, $1.1M portfolio, $45k/year income generation
  • Wealth gain: $117k equity growth
  • Cash flow: Still negative, covered by other income
  • 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

  1. Save emergency fund: $50k (in offset account, offset mortgage interest)
  2. Invest capital: $250k into 1 unit purchase
  3. Hold & stabilize: 3 years (understand property investing)
  4. Refinance: Borrow against equity, or save for property #2 deposit
  5. Scale: Buy property #2 (year 3–4)
  6. Compound: By year 10, you have $1.5M+ portfolio, $500k+ equity
