Buying a home is one of the biggest financial decisions you will ever make. Whether you’re looking in Lagos, Abuja, Port Harcourt, or any growing city in Nigeria, the first question every homebuyer must answer is simple:
“How much house can I realistically afford?”
This guide breaks everything down into simple formulas, real examples, and Nigeria-specific price insights so you can make confident decisions before buying a property.
Why Understanding Affordability Matters
- It protects you from overpaying.
- It helps you avoid future financial stress.
- It guides you toward the right locations based on your income.
- It keeps you realistic when dealing with agents and developers.
Many buyers look at house prices first, but the smart approach is to calculate your affordability before searching.
The 30–35% Monthly Income Rule
A safe rule for Nigeria is:
Your total monthly housing cost should not exceed 30–35% of your monthly income.
Formula:
Affordable Monthly Payment = Monthly Income × 0.30 to 0.35
This amount should cover:
- Mortgage or developer payment
- Service charges
- Maintenance
- Insurance (if applicable)
Example Calculation (Nigeria)
If you earn ₦600,000 monthly:
- ₦600,000 × 0.30 = ₦180,000
- ₦600,000 × 0.35 = ₦210,000
Your safe monthly payment is ₦180K – ₦210K.
This amount determines the house price you can afford.

Step-by-Step: How to Calculate Your Exact Budget
1. Determine your monthly net income
Include salary, business income, and side earnings.
2. Subtract essential expenses
Rent, feeding, bills, transportation, school fees, loans, health costs.
3. Apply the 30–35% rule
This gives you your maximum monthly housing payment.
4. Evaluate your savings
Most developers require 20–30% initial deposit.
Mortgages typically require a 20–30% down payment as well.
5. Check long-term stability
Will your income remain steady over the next 2–5 years?
Hidden Costs Most Buyers Forget
These should be included when planning your affordability:
- Legal fee: 5–7.5%
- Survey: ₦300K – ₦1.5M
- Documentation fees
- Agent commission (usually 5%)
- Service charge (₦100K – ₦750K yearly)
- Furnishing (₦500K – ₦5M+)
- Governor’s Consent (3–5% depending on state)
Always budget an extra 10–15% for these.
Nigeria-Friendly Affordability Formula
Use this to estimate your maximum house price:
Maximum House Price = (Annual Income × 4 to 5) + Current Savings – Outstanding Debt

If your annual income is ₦10M, you can typically afford:
₦40M – ₦55M
