The 28/36 Rule Explained

- Front-end ratio (28%): Your total monthly housing payment (mortgage + property tax + insurance + HOA) should be at most 28% of your gross monthly income
- Back-end ratio (36%): Your total monthly debt payments (housing + car + student loans + credit cards) should be at most 36% of your gross monthly income
Affordability by Income Bracket
| Income | Max Home (28% front-end) | Max Home (36% back-end) | Recommended (25%) |
|---|---|---|---|
| $50,000 | $168,632_28 | $168,632_36 | $168,632_REC |
| $75,000 | $252,949_28 | $252,949_36 | $252,949_REC |
| $100,000 | $337,265_28 | $337,265_36 | $337,265_REC |
| $150,000 | $505,898_28 | $505,898_36 | $505,898_REC |
| $200,000 | $674,531_28 | $674,531_36 | $674,531_REC |
The "recommended (25%)" column assumes a slightly more conservative ratio, leaving you more money for savings, retirement, and unexpected expenses. This is the sweet spot for most buyers in San Diego.

- 15-year fixed: 5.85%

Property Taxes and Other Costs
In San Diego, the total cost of homeownership includes more than just the mortgage. You should budget for:
| Cost | Annual Amount | Monthly Equivalent |
|---|---|---|
| Property tax (1.16%) | $10,672 | $889 |
| Home insurance | $1 | $0 |
| HOA fees (if applicable) | $0-6,000 | $0-500 |
| Maintenance (1%/year of home value) | $9,200 | $766 |
| Total additional costs | $19,873 | $1,656 |
These costs add about 25-40% to your total monthly housing payment. The "max home price" in the table above is based on the mortgage payment only — factor in these extras to get your true budget.
Down Payment Strategies
The 20% down payment is the gold standard because it eliminates private mortgage insurance (PMI). But there are lower down payment options:
- 3.5% down (FHA loan): Requires PMI, accessible to first-time buyers with 580+ credit score
- 5% down (conventional): Requires PMI, accessible to most buyers with 620+ credit score
- 10% down: Lower PMI than 5% down, but still required
- 20% down: No PMI, best rates, most competitive offer
- 25%+ down: Best rates, lowest monthly payment, may help in competitive markets
For first-time buyers in San Diego, the FHSA + RRSP Home Buyers' Plan can help you accumulate the down payment. See the FHSA calculator and RRSP calculator for details.
Tips to Increase Your Affordability in San Diego
1. Improve Your Credit Score
A 780+ credit score can save you 0.5-1% on your mortgage rate. On a $400,000 loan, that's $100-200/month in savings — $36,000-72,000 over 30 years. Pay down credit card balances, dispute errors, and don't open new accounts before applying.
2. Pay Off Other Debt
Lenders count your car payments, student loans, and credit card minimums against you. Paying off a $400/month car payment can increase your affordability by $80,000-100,000.
3. Increase Your Down Payment
Every extra $20,000 down can increase your max home price by ~$25,000 (since you're borrowing less). Use the Should I Buy This? calculator to evaluate tradeoffs.
4. Consider a 15-Year Mortgage
A 15-year mortgage has a higher monthly payment but a much lower rate (typically 0.5-0.75% less). If you can afford the higher payment, you'll pay $200,000+ less in interest over the life of the loan.
5. Look in Adjacent Areas
Homes 15-30 minutes outside San Diego center are often 20-40% cheaper for comparable square footage. A longer commute might be worth $100,000+ in home price.
