The 28/36 Rule (The Starting Point)
Most lenders use the 28/36 rule as a guideline:
- 28%: Your monthly housing costs (mortgage principal + interest + taxes + insurance, or PITI) shouldn't exceed 28% of your gross monthly income
- 36%: Your total debt payments (housing + car loans + student loans + credit cards) shouldn't exceed 36% of gross income
This is a lender rule — it's designed around what they'll approve, not what's comfortable for you. It uses gross income (before taxes), which overstates your real flexibility. A more conservative personal target is keeping housing under 25% of take-home pay.
The Real Costs of Homeownership
First-time buyers often focus on the mortgage payment and miss the full picture. Monthly homeownership costs include:
- Mortgage principal + interest
- Property taxes (varies significantly by state/county)
- Homeowner's insurance
- PMI if down payment is under 20% (typically 0.5–1.5% of loan annually)
- HOA fees (if applicable)
- Maintenance and repairs (budget 1% of home value per year)
- Utilities (typically higher than renting)
A Quick Affordability Estimate by Location
Housing costs vary dramatically across KC plant locations. Here's a rough monthly budget guideline for a first home in each region, based on median home prices and current mortgage rates (illustrative — verify current rates with KCCU):
| Location | Median Home Price (est.) | Monthly PITI (est. at 7%) | Suggested Min. Income |
|---|---|---|---|
| Corinth, MS / Paris, TX | $130,000–$170,000 | $900–$1,150 | ~$43,000+ |
| Jackson / Loudon, TN | $180,000–$230,000 | $1,200–$1,550 | ~$58,000+ |
| LaGrange, GA / Mobile, AL | $160,000–$210,000 | $1,100–$1,400 | ~$53,000+ |
| Memphis, TN / Owensboro, KY | $180,000–$240,000 | $1,200–$1,600 | ~$61,000+ |
| Neenah / Appleton, WI | $230,000–$310,000 | $1,550–$2,100 | ~$80,000+ |
| Chester, PA (suburban Philly) | $280,000–$400,000 | $1,900–$2,700 | ~$103,000+ |
All figures are estimates using illustrative assumptions. Verify current home prices and mortgage rates before making any decisions. Contact KCCU for current mortgage rate information.
Down Payment: How Much Do You Need?
- 20%: Avoids PMI; historically the standard
- 10%: Requires PMI but reduces time to homeownership
- 5%: Many conventional loans; PMI required
- 3.5%: FHA loans minimum (with qualifying credit score)
- 0%: VA loans (military) and some USDA rural programs
Don't drain your emergency fund for a larger down payment. Going into homeownership without liquid savings is a recipe for stress — the first repair can hit before you've rebuilt any cushion.
Check Your Credit First
Your credit score directly affects your mortgage interest rate. A difference of 50–100 points can mean a 0.5–1% difference in rate — which on a $200,000 mortgage over 30 years translates to $25,000–$50,000 in total interest. Before house-hunting, check your credit report, dispute any errors, and avoid opening new credit accounts.
