Upgrading Your Alexandria Apartment: Safe Borrowing Limits That Hold

Upgrading from an Alexandria apartment to a family home is safe when you borrow less than the bank will lend, stress‑test repayments at current rates +3%, and keep total home/investment repayments under about 30–35% of your after‑tax income.

That’s the decision line that matters more than the property photos.

1. What’s a safe borrowing limit for an Alexandria upgrade?

For inner‑Sydney borrowers, a practical rule is:

1. Model repayments at current interest rates +3%.
2. Keep total home and investment repayments ≤30–35% of after‑tax income.
3. Keep your new home loan ≤80% LVR if possible to avoid LMI and give yourself flexibility.

This aligns with how APRA expects banks to assess loans (3% buffer) and with stress benchmarks we use across Alexandria and the Eastern Suburbs.

Quick example (illustrative, not advice):

• Combined after‑tax income: $230k (around $320k gross).
• Safe repayment band (30–35%): $5,750–$6,700/month.
• At a stressed rate of 8% P&I over 30 years, that supports roughly $900k–$1.05m of total home debt.

If the bank offers you $1.3m, the safe move is to ignore that number and work off the lower figure.

From apartment equity to family home borrowing power – the key numbers in between.

2. From Alexandria apartment to house: working the equity and LVR

Most Alexandria upgraders start with an apartment worth $800k–$1.2m and a partial mortgage left.

Step 1: Estimate your usable equity

Usable equity is usually capped at 80% of value minus your current loan.

Say your apartment is worth $950k and you owe $520k:

• 80% of value: $760k
• Usable equity: $760k − $520k = $240k

If you sell, that $240k (before selling costs) can form most of your house deposit.

Step 2: Price band for a family home

Suppose you’re eyeing a $1.6m inner south house:

• 20% deposit target (to avoid LMI): $320k
• Purchase costs (stamp duty, legals, inspections): say $80k–$90k

You’d ideally want $400k+ available, or you accept either:

• Higher LVR (85–90%) + LMI, or
• A cheaper house now and upgrade again later.

Step 3: Check the new loan against your safe limit

If you had $400k cash/equity on a $1.6m house:

• New loan: $1.2m (75% LVR)
• At 6% over 30 years: ~$7,200/month
• At stressed 9%: ~$9,650/month

On $230k after‑tax income, that stressed repayment is ~50% of income – well above a safe 30–35% band.

That’s the key risk: the inner south upgrade often breaks the 35% rule unless income is strong or you keep the purchase price down.
