Double-allocation scam: two tenants, one flat, big problem

Imagine pulling up to your new flat at 9 AM on move-in day with a moving truck behind you, two-year rent already paid, tenancy agreement signed, keys in hand — and finding another tenant at the same gate, with their own moving truck, their own signed agreement, and their own set of keys that also open the front door.

This is the double-allocation scam. Two tenants pay full rent and caution for the same property to the same "landlord" in the same month. On move-in day, one of you (the unlucky one) is out ₦3-5 million and has to start the rental search again from scratch while the landlord's phone has gone to voicemail permanently.

It happens more often than people realise. This post covers how the scam works, how to detect it before you pay, and what to do on the day if it happens.

How the scam actually works

The mechanics are simple and the payoff is high, which is why this scam is increasingly common in Lagos and Abuja.

A landlord (real or fake) advertises a property on multiple platforms simultaneously — Jiji, PropertyPro, WhatsApp groups, maybe two different agents. Each channel generates its own pool of interested tenants. The landlord runs a parallel conversation with two prospects, pretending each is the only one.

Both prospects visit the property on different days (or the same day at different times). Both like it. Both agree to take it. Both are given bank details and asked to pay "the rent and caution to secure the property."

Tenant A pays on Monday. The landlord says "great, come sign the lease on Wednesday and pick up keys." Tenant B, unaware, pays on Tuesday. The landlord says the same thing, but proposes a move-in on Saturday.

By Friday, the landlord has ~₦6-10 million in their account. They have already stopped replying to one or both tenants. On move-in day, whoever shows up first takes the property (or there's a confrontation). The other tenant has no flat, no money, and no practical path to recovery.

Sometimes the scammer is the genuine owner, and the game is to collect two sets of caution and rent then hand one of them back after "apologising for the mix-up" — keeping the "mistake" caution as profit. Sometimes the scammer doesn't own the property at all and both tenants are out entirely.

Why the scam works

Three properties of the Nigerian rental market enable this:

1. Stamp duty is skipped. Most tenancy agreements in Nigeria are never stamped at the state internal revenue service. Without a stamped agreement with a unique serial number, the state has no record of the first lease existing. The landlord can execute a second, equally valid-looking agreement with no conflict visible to outsiders.
