First Home BuyerFinance ReadinessCheck.

The gap between what you think you can borrow and what a lender will approve is where most first home buyer deals fall apart. Not at the property. Not at the negotiation. At the finance. This prompt maps every variable in your position before you brief a broker or make an offer.

Why this matters

Why this matters

Most first home buyers walk into a broker conversation knowing their savings balance and their salary. That's about a third of what a lender actually assesses. The rest — HECS debt, credit card limits, buy-now-pay-later exposure, living expense allowances, and the serviceability buffer — is invisible to them.

The serviceability buffer alone is the thing that catches most first home buyers. Lenders don't assess whether you can repay at the actual rate. They assess whether you could repay at the rate plus 3%. At current rates that reduces your maximum borrowing capacity by roughly 20–25% compared to what a simple income-to-loan ratio would suggest.

This prompt maps the full picture before you see a broker. Not because it replaces the broker conversation — it doesn't. Because a client who walks in knowing their actual position gets a more useful conversation and makes better decisions.

The serviceability buffer is the variable most first home buyers don't know exists. It's also the one that most changes what they can borrow.

Heads up

Be honest with your numbers. The point of this prompt is to surface the gaps in your finance position before a broker does. Conservative inputs give you a realistic picture. Optimistic inputs give you a false sense of readiness.

Return a structured finance readiness report with exactly these 8 sections:

## 1. DEPOSIT POSITION
My deposit as a percentage of my target price. Funds remaining after deposit. Whether I'm above or below the 80% LVR threshold. Whether I'm above the 90% threshold.

Stamp duty estimate for my state at my target price. First home buyer concession or exemption if applicable. Legal fees estimate. Building and pest estimate. Total estimated cost beyond the deposit.

## 3. TOTAL FUNDS TO COMPLETE
Deposit plus stamp duty plus costs. Gap between my current savings and total funds required.

## 4. GOVERNMENT SCHEME ELIGIBILITY (assumptions only)
First Home Guarantee: 5% deposit no LMI, price cap for my state, eligibility assumption.
State-based first home owner grant: amount and eligibility assumption.
Flag: scheme eligibility depends on income, property type, and current availability. Verify with your broker.

## 5. BORROWING CAPACITY SIGNAL

Case Study

The HECS debt that changed the borrowing capacity.

A teacher in Sydney, 29 years old, gross income $95,000. Saved $85,000. Targeting $750,000 in the inner west. Came to me thinking she had enough for a 10% deposit with costs covered. The readiness check told a different story.

Two factors she hadn't accounted for changed her number significantly.

AI · HECS TreatmentHECS/HELP balance of $52,000. Australian lenders assess HECS as a monthly liability even when repayments are income-contingent. At $95,000 gross, compulsory repayment is approximately 3% = $2,850/year = $237/month. This reduces assessed monthly surplus and therefore borrowing capacity. Estimated impact: approximately $40,000–$55,000 reduction depending on lender.
AI · Credit Card LimitsTwo credit cards, combined limit $18,000, both currently at zero balance. Lenders typically assess credit card exposure at approximately 3% of the limit per month regardless of actual balance: $540/month in assumed repayments. Recommendation: if you won't use these cards in the purchase period, consider reducing limits to $5,000 total before applying.
AI · Revised EstimateRevised borrowing capacity signal with HECS and credit card treatment: approximately $470,000–$510,000 depending on lender. At 90% LVR that implies a purchase price of approximately $520,000–$565,000. To reach $750,000, deposit required at 90% LVR plus LMI: approximately $135,000. Gap to target: approximately $50,000.

She wasn't ready for $750,000. She was ready for $580,000 — which was still a viable property in the right suburb at the right configuration. She reduced her credit card limits before applying, which recovered about $30,000 in capacity. She bought 11 months later at $625,000 in a suburb she hadn't previously considered.

Step 04 · Refine

Your first run is fine. Your fifth is sharp.

Tune 01

Run it with your broker's actual numbers

After your first broker meeting, update the prompt with your formal borrowing capacity figure. Now the readiness check is calibrated to your actual position, not an estimate.

Tune 02

Re-run every 3 months

Your savings grow. HECS balances change. Credit card limits can be adjusted. Run the readiness check quarterly so your picture stays current.

Tune 03

Test different price points

Run the prompt three times: at your target price, $50,000 below, and $100,000 below. See what changes at each point — especially the LMI threshold and the government scheme price caps.

Save it

Save this readiness check in a Claude Project alongside your Day 02 strategy. Update it whenever your financial position changes. The gap between your current readiness and your target property is the plan.

The honest bit

What it still gets wrong.

i.

Borrowing capacity varies by lender

The same income, HECS balance, and credit card limits produce different borrowing capacity numbers at different lenders. This prompt gives you a signal. Your broker gives you the actual assessment.

ii.

Government scheme availability changes

First Home Guarantee allocations run out. Price caps adjust. Eligibility rules change. Verify current scheme availability with your broker, not this prompt.

iii.

Stamp duty concession thresholds move

Every state updates thresholds, usually in the budget. Verify the current threshold for your state before relying on any duty calculation from this prompt.

iv.

Savings pattern matters more than savings balance

Lenders assess not just your deposit amount but how it was accumulated. Genuine savings over three months is a standard requirement. Tell Claude your savings history, not just the total.

The Workflow

How this stacks.

Day 03 maps your finance position. Day 06 stress-tests your borrowing power against different rate scenarios. Day 29 builds your broker meeting preparation pack. Run them in sequence before your first broker conversation.

The week three vision

Before your first broker meeting.

You'll know what a lender sees when they look at your file.

You'll walk in knowing your deposit position at every LVR point, your stamp duty exposure in your target state, which government schemes you likely qualify for, the impact of your HECS balance on your borrowing capacity, and the three things you should fix before your application goes to a lender. That's not a typical first home buyer. That's a client a broker can efficiently help.
