There is a stubborn belief among Nigerians abroad that a house is a “store of value.”
The logic goes like this: You build a house in Benin City. You lock the doors. You fly back to London. The house sits there, safe and static, waiting for you to return. It is a vault for your money.
This is a dangerous misconception. A house is not a gold bar. It is not a bank account. A house is a machine. It is a complex system of pumps, seals, wires, and finishes that requires constant operation to function.
When you leave a machine running, it wears out slowly. When you turn a machine off and leave it in a tropical climate for eleven months, it doesn’t just pause. It begins to die.
The Physics of Stagnation
The first enemy of the unoccupied house is not the burglar; it is the atmosphere.
In Nigeria, we have two extremes: intense humidity and intense dust. An occupied house fights these naturally. You open windows, creating airflow that prevents mold. You walk on floors, preventing dust from cementing into grime. You flush toilets, keeping water seals wet.
In an empty house, the air stops moving. This stagnation creates three distinct hazards:
- The Mold Bloom: Humidity gets trapped behind wardrobes and inside gypsum ceilings. Without cross-ventilation, mold spores settle on leather furniture and walls.
- The Dry Rot: Paradoxically, while the air is wet, the plumbing dries out. The rubber seals in your faucets and toilet tanks need moisture to stay flexible. When they dry, they crack.
- The Sewer Gas: Every sink and floor drain has a “P-trap”—a U-shaped pipe holding water that blocks sewer gas. In an empty house, this water evaporates. The seal breaks. . Sewer gas (and cockroaches) then have a direct highway from the septic tank into your bedroom.
The Mechanical Seizure
The most expensive components of your house—the generator, the borehole pump, the air conditioner—are designed to move.
If you leave a diesel generator unused for a year, the fuel degrades into sludge. The battery dies. The pistons seize. When you return in December and try to start it, you don’t just need a service; you often need a new engine.
We recently audited a property in GRA, Benin, that had been locked for two years. The owner thought it was pristine. In reality, the borehole pump had seized from rust, the AC compressors were stuck, and the inverter batteries were completely dead (sulfated) because they were never charged.
The cost to bring the house back to life was N3.5 million. The owner had “saved” nothing.
The Financial Calculus
Let’s look at the numbers.
If you build a standard 4-bedroom duplex in a decent area, its potential rental value is perhaps N3 million to N5 million per year.
By keeping it empty for your two-week Christmas visit, you are effectively paying N5 million for accommodation. That is roughly N350,000 per night. You could stay in the most expensive hotel suite in Edo State for a fraction of that cost, with zero maintenance liability.
You are paying a premium to watch your asset depreciate.
The “New” Premium
The counter-argument is usually, “I want it to stay new.”
But a house does not stay new by being ignored. It stays new by being maintained. A house with a tenant (or a facility manager) who spots a roof leak immediately is in better condition than a house where a roof leak goes unnoticed for six months, rotting the ceiling rafters.
The “newness” you are trying to protect is an illusion. You are protecting the cosmetic surface while the infrastructure decays.
Frequently Asked Questions
1. Does insurance cover damage if the house is empty? Almost never. Most Nigerian insurance policies have a “vacancy clause.” If the property is unoccupied for more than 30 or 60 consecutive days, coverage for theft, vandalism, and water damage is void. You are self-insuring against total loss.
2. Can I just ask my neighbor to open the windows once a month? You can, but “airing” isn’t enough. To prevent mechanical seizure, the generator needs to run under load. The toilets need flushing. The ACs need cycling. A neighbor doing you a favor won’t do a technical audit; they will just open a window and leave.
3. If I rent it out, won’t the tenant destroy it? This is the fear. But the solution isn’t “don’t rent”; the solution is “vet properly.” A professional property manager screens tenants for employment history and character. We also hold “security deposits” to cover damages. A good tenant pays you to keep your pipes working.
4. What is “Caretaker Management”? This is a service for owners who absolutely refuse to rent. You pay a monthly fee for a professional (not a cousin) to visit weekly. We run the water, start the generator, check for leaks, and clean the dust. It costs money, but it is cheaper than replacing a seized engine.
5. Can I use Short-Let (Airbnb) instead of a long-term tenant? Yes. This is the hybrid model. It keeps the house available for your visits but generates income the rest of the year. However, it requires intense management—cleaning, check-in, check-out. It turns your house into a business.
You have two choices: turn your house into an asset that pays you, or accept that it is a liability that costs you.
