What is a Construction Loan?

A construction loan is a specialized mortgage designed for building a home rather than buying an existing one. Unlike a standard mortgage where you receive the full loan amount at once, construction loans release funds in phased drawdowns as construction progresses.

💡 Key Insight: During construction, you typically pay interest only on the amount drawn so far. Once construction is complete, the loan converts to a standard mortgage with principal + interest payments.

How Construction Loans Work

The Drawdown Process

Instead of receiving the full loan amount upfront, funds are released at key construction milestones:

1
Foundation & substructure — First drawdown after foundation is complete
2
Wall & floor slab — After walls and ground floor slab
3
Roof & external walls — After roof installation
4
Finishes & fittings — Internal finishes, plumbing, electrical
5
Final completion — Last drawdown after inspection

Interest During Construction

Conversion to Standard Mortgage

📊 Example Timeline:
  • Month 1-6: Construction period — pay interest only (~KES 15,000-30,000/month)
  • Month 7 onward: Loan converts — pay principal + interest (~KES 55,000/month)

Pros & Cons of Construction Loans

✅ Advantages

  • Lower payments during construction — Interest-only period
  • Pay only for what you've built — Drawdown structure
  • Build exactly what you want — Custom design and finishes
  • Potential cost savings — No developer profit margin
  • Bank oversight — Regular inspections ensure quality
  • Can use land as collateral — Land equity reduces deposit

❌ Disadvantages

  • More documentation required — Architectural plans, building permits
  • Interest rate risk — Variable rates during construction
  • Construction delays — Drawdowns tied to milestones
  • Cost overruns risk — You may need extra funds
  • Higher interest rate — Typically 0.5-1% above standard mortgage

Requirements for a Construction Loan

Land Requirements

Construction Documents

Contractor Requirements

⚠️ Important: Banks require verified invoices and sometimes site inspections before each drawdown. Keep all receipts and contractor documentation organized.

Loan-to-Value (LTV) & Deposit Requirements

ComponentFinancing AvailableYour Contribution
Land value (if owned) Up to 80% of land value counts as equity 20% of land value (imputed)
Construction costs (BOQ) Typically 80-90% 10-20% cash deposit
Total financing Up to 90% of total project (land + construction) 10-20% cash + land equity

💡 Pro Tip: If you already own the land, its value serves as your deposit. You may need little to no additional cash beyond construction costs.

Hidden Costs of Construction Loans

⚠️ Always budget a contingency fund of 10-15% above your BOQ. Construction almost always costs more than initially estimated.

Renovation & Home Improvement Loans

If you already own a home but need financing for major renovations or extensions:

💡 Pro Tip: Some banks offer "home improvement loans" as personal loans (not secured by property). These have higher interest rates (15-20%) but faster approval.

Frequently Asked Questions

Can I act as my own contractor (owner-builder)?

Some banks allow owner-builders, but they typically require proof of construction experience or a background in building. Most banks prefer licensed contractors.

What if construction costs exceed the loan amount?

You are responsible for cost overruns. That's why we recommend a 10-15% contingency fund. Some banks may offer additional financing, but not guaranteed.

How long does construction loan approval take?

Longer than standard mortgages — typically 6-10 weeks. The bank must review architectural plans, BOQ, contractor credentials, and conduct multiple valuations.

What happens if construction is delayed?

You continue paying interest-only during the delay. Most banks allow 12-24 months for construction. Extensions may incur fees.
