What is a mortgage system?
A mortgage system is a financial and legal framework that enables individuals, groups and businesses to acquire or develop real estate by borrowing from financial institutions and repaying the principal and interest over an agreed period, typically spanning several years.
Instead of paying the full cost upfront, the buyer contributes an initial amount, known as equity or a down payment, while the mortgage lender provides the balance. The borrower subsequently repays the loan through monthly instalments covering principal and interest.
The property serves as collateral for the mortgage. The buyer (mortgagor) retains ownership, subject to the lender’s (mortgagee’s) security interest. If the borrower defaults, the lender may enforce its security rights in accordance with the mortgage agreement and applicable laws.
Mortgage interest rates may be fixed or variable, depending on the loan terms. A fixed rate provides repayment certainty, while a variable rate may change with market conditions.
In Nigeria, mortgage financing remains severely underdeveloped. The country’s mortgage-to-GDP ratio is frequently cited at less than one per cent, reflecting the limited penetration of formal housing finance. Meanwhile, the National Housing Data Technical Committee puts Nigeria’s 2025 housing deficit at 14.925 million units.
Why the mortgage system is struggling
High monetary policy rate: Nigeria’s Monetary Policy Rate (MPR) was reduced from 26.5 percent to 23 percent by the Central Bank of Nigeria (CBN) in September 2026. By comparison, the US Federal Reserve’s Federal Funds Rate target range was 3.75–4.00 percent, while the Bank of England’s Base Rate was 3.75 percent. Although these policy rates are not directly equivalent to mortgage lending rates, they illustrate the differences in monetary conditions and funding costs.
With an MPR of 23 percent, affordable long-term commercial mortgage financing remains difficult. Government intervention may therefore be necessary. However, subsidised mortgage financing increasingly resembles social investment, as illustrated by the MOFI Real Estate Investment Fund (MREIF), rather than a fully market-driven mortgage system. Its limited initial funding also restricts the number of beneficiaries.
Poor salaries and wages: The earnings of many formal and informal workers are inadequate to support mortgage repayments. Nigeria’s N70,000 minimum wage offers limited purchasing power relative to prevailing housing costs. Even highly educated professionals, including university professors, may struggle to service mortgages because of the disparity between their earnings and residential property prices.
High interest rates and inflation: Commercial lending rates remain elevated, with some Nigerian banks charging between 20 percent and 30 percent or more, depending on the borrower and loan category. These financing costs, combined with inflation, make monthly mortgage repayments unaffordable for many average-income earners.
Funding mismatch: Most financial institutions rely significantly on short-term deposits to finance lending. This creates an asset-liability mismatch, making it difficult for banks to provide housing loans extending over 20 to 30 years. Mortgage financing requires stable, long-term funding.
Cumbersome land administration: Obtaining a Certificate of Occupancy (C of O) or Governor’s Consent under the Land Use Act 1978 can be slow, bureaucratic and expensive. Weak land administration delays property transactions and mortgage collateralisation, leaving much of Nigeria’s land outside the formal financial system and effectively turning it into dead capital.
Exclusionary housing finance frameworks: Public schemes such as the National Housing Fund (NHF) and primary mortgage institutions face challenges involving public awareness, bureaucratic bottlenecks and limited loanable funds. Consequently, many low- and middle-income earners remain excluded from mortgage financing.
Informal employment and weak credit records: A significant proportion of Nigeria’s workforce operates in the informal economy. Many traders, artisans and self-employed individuals lack conventional employment records, verifiable income documentation and formal credit histories, making it difficult to qualify for mortgages.
Developers’ preference for cash payments: High financing costs and mortgage processing delays encourage developers to favour outright cash payments or substantial upfront contributions through off-plan property schemes. This bypasses mortgage financing and exposes buyers to fraud. Reports have put losses from fraudulent property transactions in Lagos, Abuja and Port Harcourt at about N3 trillion, although this figure should be treated as an industry estimate rather than an independently verified national statistic. Diaspora Nigerians have featured prominently among reported victims.
Corruption: Corruption also undermines mortgage financing. Where illicit funds influence property acquisition and development, formal housing finance institutions operate in an environment where transparency and financial discipline are weakened.
Low financial participation: EFInA’s 2026 Access to Financial Services Survey reports that 79 percent of Nigerian adults are financially included, up from 74 percent in 2023. However, financial inclusion does not automatically translate into access to mortgage credit. Limited borrowing capacity, unemployment and reluctance to access conventional interest-bearing loans because of religious beliefs further constrain mortgage adoption.
What needs to change?
Nigeria needs structural reforms to make its mortgage system effective, efficient and economically sustainable. Workers’ incomes must improve, while housing costs must come down through greater adoption of locally sourced and affordable building materials, including timber and cement-free walling systems.
The country must also develop sustainable long-term funding for mortgage institutions, modernise land administration, strengthen property registration and introduce lending frameworks that accommodate informal-sector workers.
Ultimately, salaries are too meagre and housing costs too high for mortgage financing to make a significant impact on housing provision in Nigeria.
Although MREIF offers mortgages at 9.75 percent per annum, with repayment terms of up to 20 years, its initial N250 billion tranche comprises N150 billion in government concessionary funding and N100 billion in commercial funding. It forms part of a broader N1 trillion programme. By August 2026, the fund had reportedly disbursed over N140 billion, supporting 2,018 mortgages across 27 states.
Even at an average loan of N50 million, N250 billion would finance only 5,000 mortgages, illustrating the limitations of relying on subsidised financing to address a housing deficit of nearly 15 million units.
Nigeria therefore needs broader economic and institutional reforms to make housing affordable and mortgage financing accessible to a much larger proportion of its population.
