📚 What is the 28/36 Rule (Plain English)
The 28/36 rule is two percentages that limit how much of your income can go to debt:
🔹 28% "Front-End" DTI: Housing costs (Principal + Interest + Taxes + Insurance) ≤ 28% of gross monthly income
🔹 36% "Back-End" DTI: ALL monthly debt (housing + car + student + credit + child support) ≤ 36% of gross monthly income
Real Example: Jake, $8,000/month income
| Gross monthly income | $8,000 |
| Max housing (28%) | $2,240/mo |
| Max total debt (36%) | $2,880/mo |
| Existing car loan | –$450/mo |
| Student loans | –$180/mo |
| Real max housing for Jake | $2,250/mo (28%) OR $2,250/mo (36% after debts) = $2,250/mo |
At 6.75% rate + $500 taxes/insurance, Jake can afford approximately a $290,000 home with 10% down.

⚠️ 7 Hidden Costs Most Buyers Forget
The 28/36 rule only covers PITI. Here's what else eats your monthly budget:
HOA / Condo fees
For condos, PUDs, planned communities. Adds directly to housing DTI.
$200–$600/mo
Home maintenance
$300K home = $3K–$9K/yr. Roof, HVAC, appliances break on schedule.
1–3% of home value/yr
Utilities increase
Most homes use 2–3× the energy of apartments. Budget accordingly.
+$100–$300/mo
Lawn / landscape
DIY or pro service. Ignored by renters, crushing for buyers.
$50–$200/mo
Property tax increases
Reassessments after purchase often spike taxes. Texas/NJ especially painful.
+3–10%/yr
Insurance increases
Climate-driven jumps in FL, CA, TX, LA. Budget for this.
+5–20%/yr (2026)
Furniture + setup
Window treatments, appliances, move, fresh paint. Budget $10K buffer.
$5K–$25K one-time
❓ 28/36 Rule & Affordability FAQ 2026
Q: Should I borrow up to my max approval amount?
No. Lenders approve you at the MAX possible ratios, but buying at your max leaves you "house poor" — no money for emergencies, investing, or life. Rule of thumb: aim for a purchase at 80% of your max approval. If approved for $400K, buy a $320K house. You'll have cash flow for repairs, investments, vacations, and rate-cutting refinances.
Q: Do bonuses and overtime count for affordability?
Sometimes. Lenders use conservative income rules: (1) Base salary — 100% counts. (2) Bonus income — must have 2+ year history, averaged. (3) Overtime — must be "consistent" (2+ year history), averaged. (4) Commission — averaged over 2 years. (5) Part-time job — must have 2+ years. (6) Side hustle (1099) — must have 2 years tax returns. If you just got a raise or big bonus, lenders won't count it until you have a full year of history.
Q: Can I use a co-signer to afford more house?
Yes — a non-occupant co-signer can boost your DTI calculation. FHA specifically allows this. The co-signer's income is added to yours; their debts are also added. Best candidates: parents with paid-off homes and good income. Risks: co-signer is 100% liable if you default; affects their DTI for their own loans. Alternative: have the co-signer GIFT you down payment funds (allowed on FHA, conventional, VA) instead of co-signing. Cleaner for everyone.
