The 28/36 Rule Explained
The 28/36 rule is the cornerstone of mortgage affordability. It states: spend no more than 28% of gross monthly income on housing costs (front-end ratio) and 36% of gross monthly income on total debt (back-end ratio).
Housing costs in the 28% rule include: mortgage principal + interest + property taxes + homeowner's insurance (PITI) + HOA fees + PMI if applicable.
Example: Income €100,000/year = €8,333/month. Max PITI = €8,333 × 0.28 = €2,333. Max total debt = €8,333 × 0.36 = €3,000.
With €500 in existing monthly debts, you have €3,000 − €500 = €2,500 available for housing — limited by the back-end rule to €2,500 (not the €2,333 front-end maximum in this case).
Down Payment Impact on Affordability
Your down payment dramatically affects what you can afford and what you pay:
| Down Payment % | PMI Required? | Monthly Cost Impact | Upfront Cash Needed (€400K home) |
|---|---|---|---|
| 3% (FHA) | Yes (MIP, permanent) | +€200–400/mo | €12,000 |
| 5% | Yes (~0.5-1.5%/yr) | +€150–300/mo | €20,000 |
| 10% | Yes (lower rate) | +€75–150/mo | €40,000 |
| 20% | No | €0.00 | €80,000 |
PMI (Private Mortgage Insurance) typically costs 0.5–1.5% of the loan amount annually. On a €350,000 loan at 1%, that's €3,500/year or €292/month — a significant chunk of housing budget.
Mortgage Rate Impact on Affordability
Interest rates have a massive effect on home buying power. For a €400,000 home with 20% down (€320,000 loan):
| Interest Rate | Monthly P&I | Total Interest Paid |
|---|---|---|
| 4.0% | €1,527 | €229,736 |
| 5.0% | €1,718 | €298,521 |
| 6.0% | €1,919 | €370,829 |
| 7.0% | €2,129 | €446,516 |
| 8.0% | €2,348 | €525,523 |
A 1% rate increase on a €320,000 loan adds ~€200/month to your payment. This is why refinancing (or buying when rates are lower) saves hundreds of thousands over a 30-year loan.
Hidden Costs of Homeownership
First-time buyers often underestimate true homeownership costs beyond the mortgage payment:
- Property taxes: Typically 0.5–2.5% of home value annually (€2,000–€10,000+ on a €400K home)
- Homeowner's insurance: €800–€2,000/year depending on location and coverage
- Maintenance and repairs: Budget 1–2% of home value annually (€4,000–€8,000 on a €400K home)
- HOA fees: €100–€1,000+/month for condos and planned communities
- Utilities: Higher than renting — €200–€600/month for a house vs. apartment
- Closing costs: 2–5% of purchase price (€8,000–€20,000 on a €400K home)
The true monthly cost of homeownership is often 25–40% higher than the mortgage payment alone. Factor these into your budget before committing.
How Lenders Calculate Maximum Loan Amount
Lenders use both DTI ratios and loan-to-value (LTV) ratios to determine maximum mortgage amounts. The lower of these two limits applies:
- Income-based limit: Maximum monthly payment × 12 months / annual rate factor
- Property-based limit: Appraised value × maximum LTV (typically 80% without PMI, 95–97% with PMI or FHA)
Credit score also affects the maximum loan. With a 620 credit score, you may only access FHA financing with a higher rate. A 760+ score unlocks the best conventional rates and more flexible terms.
First-Time Homebuyer Programs
If you're a first-time buyer (or haven't owned a home in 3 years), you may qualify for assistance:
- FHA loans: 3.5% down with 580+ credit score; 10% down with 500–579
- USDA loans: 0% down for rural/suburban properties; income limits apply
- VA loans: 0% down for eligible veterans and service members; no PMI
- State/local programs: Down payment assistance grants of €5,000–€25,000+ in many states
- Good Neighbor Next Door: 50% off for teachers, law enforcement, firefighters, EMTs in HUD-designated areas
Rent vs. Buy: When Does Buying Make Sense?
Use the price-to-rent ratio (P/R) to decide: P/R = Home Price ÷ Annual Rent. Below 15: buying is clearly better. 15–20: depends on personal factors. Above 20: renting may be financially smarter.
Other factors favoring buying: plan to stay 5+ years, stable income, building equity/wealth, desire to customize, tax benefits (mortgage interest deduction for itemizers). Factors favoring renting: need flexibility, market at peak, high maintenance costs, better investment opportunities elsewhere.

Frequently Asked Questions
How much house can I afford on €60,000 a year?
On €60,000/year (€5,000/month), the 28% rule gives €1,400/month for housing (PITI). At a 7% rate with 20% down, this translates to roughly €175,000–€200,000 purchase price depending on taxes and insurance in your area.
How much house can I afford on €100,000 a year?
€100,000/year = €8,333/month. Max PITI at 28% = €2,333/month. At 7% for 30 years with 20% down, this supports approximately €290,000–€330,000 in purchase price.
What credit score do I need to buy a house?
Minimum: 500 (FHA with 10% down). Practical minimum: 620 for most conventional loans. Best rates: 740–760+. Each 20-point improvement in credit score can improve your rate by 0.25–0.5%, saving tens of thousands over the loan life.
How much do I need for a down payment?
Minimum: 3% conventional, 3.5% FHA, 0% VA/USDA. Recommended: 20% to avoid PMI. On a €350,000 home, 20% = €70,000. Many buyers use 5–10% and accept PMI to buy sooner.
Is it better to get pre-qualified or pre-approved?
Pre-approval is better. Pre-qualification is a quick estimate based on self-reported data. Pre-approval involves verified income, credit pull, and asset verification — it's a conditional commitment from a lender and strengthens your offer.
What is the rule of thumb for home affordability?
The most common rules: (1) 28/36 rule — PITI ≤28% of gross income, total debts ≤36%. (2) 2.5–3x income rule — home price ≤ 2.5–3× annual gross income. Both are starting points; adjust for local market conditions.
How does student debt affect home buying?
Student loans count as monthly debt payments in DTI calculations. Even in deferment, lenders typically count 0.5–1% of the balance as a monthly payment. High student debt significantly reduces maximum mortgage amount.
Can I buy a house with no down payment?
Yes, through VA loans (veterans), USDA loans (rural areas), or some state/local first-time buyer programs. No-down-payment loans result in higher monthly payments and immediate negative equity if the market drops.
What is included in a mortgage payment?
A full mortgage payment (PITI) includes: Principal (loan repayment), Interest, property Taxes (escrowed), and homeowner's Insurance (escrowed). May also include PMI, HOA fees, and flood insurance.
How do I get the best mortgage rate?
Key factors: credit score (760+ for best rates), down payment (20%+ for no PMI), loan type (conventional vs. FHA), loan amount, and lender competition. Shop at least 3–5 lenders and consider mortgage brokers who access multiple wholesale lenders.
