How Much House Can You Actually Afford?
Pre-approval tells you what lenders will give you, not what you should spend. Use these guidelines:
| Rule | Monthly Housing Cost | Why |
|---|---|---|
| Lender’s max (43% DTI) | Up to 43% of gross income | What you qualify for |
| Conservative (28% rule) | 28% of gross income | Leaves room for saving and lifestyle |
| Comfortable (25% rule) | 25% of take-home pay | Accounts for taxes, insurance, maintenance |
Pre-Approved Amount vs. Comfortable Amount
| Gross Income | Pre-Approved for (43% DTI) | Comfortable (25% take-home) | Difference |
|---|---|---|---|
| $75,000 | $330,000 | $245,000 | $85,000 |
| $100,000 | $440,000 | $330,000 | $110,000 |
| $125,000 | $550,000 | $410,000 | $140,000 |
| $150,000 | $660,000 | $490,000 | $170,000 |

Pre-Approval Tips
| Tip | Why |
|---|---|
| Get pre-approved before house hunting | Know your budget and show sellers you’re serious |
| Apply with 2-3 lenders | Rates and terms vary; compare within the shopping window |
| Don’t change jobs during the process | Employment stability is critical for approval |
| Don’t make large purchases | Big credit card charges or car loans change your DTI |
| Don’t open new credit accounts | Hard inquiries and new debt both hurt |
| Don’t move money around | Large, unexplained deposits require documentation |
| Keep a copy of your pre-approval letter | You’ll submit it with every offer |
| Renew before it expires | If your search takes longer than 60-90 days |
What Can Go Wrong After Pre-Approval
| Issue | How It Affects Approval | How to Avoid |
|---|---|---|
| Job loss or pay cut | Income no longer supports the loan | Don’t leave your job until after closing |
| Large purchase (car, furniture) | Increases DTI, may exceed limits | Wait until after closing |
| New credit card or loan | Hard inquiry + new debt | Don’t apply for any credit |
| Late payments | Credit score drops | Pay everything on time |
| Large cash deposits | Lender must source all funds | Don’t accept cash or move money around |
| Appraisal comes in low | Loan amount exceeds property value | Negotiate price down or cover the gap |
| Major negative on credit report | Collections, judgments | Monitor your credit throughout |
