The Economics of Buying Property Off-Plan
Buying property off-plan means purchasing a property before construction is fully completed. Depending on the development, this could mean buying during the planning stage, at the beginning of construction, or at another stage before completion.
For investors, the attraction is usually straightforward: the opportunity to enter a development earlier rather than waiting until the property is completed.
However, buying early should not be viewed as an automatic guarantee of profit. A proper investment decision considers the purchase price, location, development quality, market demand, payment structure, expected rental performance and the investor’s time horizon.
Why Entry Price Matters
The price at which an investor enters a property investment can have a significant effect on the eventual outcome.
Consider a simple hypothetical example.
An investor purchases an apartment off-plan for ₦50 million. By the time the development is completed, comparable completed apartments in the same market are selling for ₦60 million.
The difference is ₦10 million, representing a 20% nominal increase from the original purchase price.
However, this should not automatically be interpreted as a 20% investment return.
The investor may also have incurred legal fees, documentation costs, financing costs, furnishing expenses, service charges or other applicable costs. Market conditions may also have changed during the construction period.
This is why experienced investors consider the total economics of an acquisition rather than simply comparing the initial purchase price with a later asking price.
Why Off-Plan Prices Can Change During Construction
Property developments are completed in stages.
A project may move from planning and site preparation through foundation works, structural construction, mechanical and electrical installations, finishing and eventually completion.
As construction progresses, the nature of the opportunity changes.
An investor purchasing very early is committing capital when a greater portion of the development is still to be completed. Someone purchasing much later can physically observe considerably more of the finished asset.
Developers may therefore review prices during the development period based on factors such as construction progress, prevailing market conditions, development costs and commercial considerations.
Any future price movement, however, remains dependent on the specific development and wider property market.
Payment Structure Is Part of the Investment
Purchase price is only one component of a property transaction.
The payment structure can also be important.
For example, an off-plan development may permit qualified buyers to make payments over an agreed period rather than paying the entire purchase price immediately.
This can allow an investor to structure the acquisition around available capital and expected cash flow.
Investors should carefully review the applicable payment schedule, deposit requirements and contractual terms before committing to a purchase.
A longer payment period should not automatically be interpreted as a cheaper investment. The relevant question remains whether the overall acquisition makes financial sense.
Location Still Matters
Buying early cannot compensate for weak underlying demand.
The long-term performance of a property is influenced by factors such as accessibility, surrounding infrastructure, employment and commercial activity, population characteristics, availability of comparable properties and demand from prospective residents or tenants.
Different locations can also support different types of property.
An area with strong demand for smaller apartments, for example, may produce different investment dynamics from an area where family-sized accommodation dominates demand.
This is why property development and investment analysis should begin with understanding the market rather than simply choosing a building design.
Rental Demand Matters
For investors purchasing property primarily to generate income, potential rental performance deserves particular attention.
A basic way of evaluating an income-producing property is through gross rental yield:
Gross Rental Yield = Annual Gross Rental Income ÷ Total Acquisition Cost × 100
For example, if an investor has a total acquisition cost of ₦60 million and the property generates ₦6 million in gross rental income during a year, the gross rental yield would be 10%.
This is only a starting point.
Gross rental income does not account for operating expenses.
Depending on the property and rental model, expenses may include management, maintenance, utilities, service charges, repairs, insurance, marketing, cleaning, furnishing replacement and periods when the property is unoccupied.
Investors should therefore distinguish between projected revenue and the income remaining after relevant expenses.
Short-Let Property Requires Additional Analysis
Short-let apartments operate differently from conventional annual rentals.
Revenue can depend on nightly rates, occupancy, seasonality, location, competition, property quality, management and operating expenses.
For example:
Annual Gross Revenue = Average Nightly Rate × Occupied Nights
An apartment charging ₦100,000 per night does not necessarily generate ₦36.5 million annually because that calculation assumes the apartment is occupied every night of the year.
A more realistic analysis incorporates an estimated occupancy rate.
If the same apartment achieved an average occupancy of 60%, the simplified calculation would be:
365 days × 60% = 219 occupied nights
219 × ₦100,000 = ₦21.9 million gross annual revenue
Even this figure would still represent gross revenue rather than profit because operating expenses would need to be deducted.
This is why rental projections should be based on reasonable assumptions and relevant market information rather than headline nightly rates alone.
Appreciation and Cash Flow Are Different
Property investors generally look at two different potential sources of economic value.
The first is capital appreciation — an increase in the market value of the property over time.
The second is cash flow — income generated by renting or otherwise commercially operating the property.
A property can experience appreciation without producing strong rental income. Another property may generate attractive rental income while experiencing relatively modest price appreciation.
Investors should therefore understand what they are buying the property to achieve.
An investment intended primarily for rental income should be assessed differently from a property purchased primarily for long-term capital preservation or future resale.
Consider the Total Acquisition Cost
A common analytical mistake is to calculate investment performance using only the advertised purchase price.
Suppose an apartment costs ₦50 million, but additional amounts are required for applicable documentation, legal services, furnishing or other costs necessary to prepare the property for its intended use.
The investor’s actual capital commitment may therefore be greater than ₦50 million.
A more complete calculation is:
Total Acquisition Cost = Purchase Price + Applicable Acquisition Costs + Costs Required to Prepare the Property for Its Intended Use
Understanding the total acquisition cost makes comparisons between different investment opportunities more meaningful.
Time Changes the Economics
Time is another important component of an off-plan investment.
A 20% increase over one year is economically different from a 20% increase over four years.
Investors should therefore consider not only how much an asset may increase in value, but also how long their capital is committed before the property becomes available for occupation, rental or resale.
Inflation should also be considered when evaluating long-term performance because an increase in the nominal price of an asset does not necessarily represent an equivalent increase in purchasing power.
Due Diligence Comes Before Returns
Financial projections should never replace proper due diligence.
Before purchasing a property, prospective buyers should independently review the information relevant to the particular transaction. Depending on the property and transaction structure, this may include title documentation, contractual terms, applicable approvals, payment obligations, specifications and other relevant documentation.
Professional legal, financial or other specialist advice may also be appropriate depending on the circumstances of the buyer and the transaction.
The objective is not simply to identify an attractive projected return.
It is to understand the asset being purchased, the terms under which it is being purchased and the assumptions behind its expected performance.
A Better Way to Think About Off-Plan Investment
Instead of asking:
“How much will this property appreciate?”
An investor can ask a broader set of questions:
What am I paying today?
What is my total acquisition cost?
What comparable properties exist within the market?
What type of rental demand exists in the location?
What income could the property reasonably generate?
What expenses would be required to operate it?
How long am I prepared to hold the investment?
What assumptions am I making about future market conditions?
These questions create a more disciplined framework for evaluating property.
The Bottom Line
Buying property off-plan can provide investors with an opportunity to participate in a development before completion, potentially access structured payment arrangements and position themselves for the future use, rental or resale of the completed property.
But the fundamental principle remains simple:
Buying early is not enough. Buying well matters more.
A sound property decision considers the entry price, location, market demand, development quality, payment structure, total acquisition cost and intended investment strategy together.
The strongest investment decisions are therefore not based solely on promises of future appreciation. They are based on research, reasonable assumptions, appropriate due diligence and a clear understanding of what the investor wants the property to achieve.
