Your tenant's lease changes what you own

When a commercial property is let, an investor is not really buying the walls. They are buying the lease. So the document your tenant signed can matter more to the value than anything about the building.

Why the lease carries the value

A let property produces income, and that income is only as reliable as the agreement behind it. Change the tenant, the remaining term or the terms themselves, and the same building becomes a different investment.

What raises value

• A long remaining term. Years of contracted income is exactly what an investor is paying for.
• A strong tenant. An established company that will still exist in five years reduces the buyer's risk, and lower risk means a higher price for the same rent.
• Built in rent increases. A lease with regular escalations protects income against inflation. One without them quietly loses value every year.
• A lock in period. A tenant who cannot simply walk away next quarter is worth more.
• The tenant paying outgoings. Where the tenant bears taxes and maintenance, more of the rent reaches you, and net income is what drives value.
• A tenant who has fitted out heavily. Somebody who has spent significantly on the space is far more likely to renew.

What reduces it

• A lease about to end, with no indication of renewal. The buyer is really buying a vacant unit with a small income tail.
• Rent below the market. Common with long standing tenants. It caps income until the lease ends, and it is one of the most frequent reasons a valuation disappoints an owner.
• A tenant with an early exit right the owner does not have.
• A weak or unknown tenant, or one whose trade is struggling.
• Unusual obligations on the landlord, such as major repairs or fit out contributions.
• Very old protected tenancies, which are a different world entirely and can reduce value dramatically. Those are covered under litigation valuation, because they usually end up there.

The rent below market problem, in numbers

Suppose your shop is let at four lakh a year, but similar shops now command six. A buyer values what they will actually receive, which is four, until the lease ends.

So your property is worth less than an identical shop next door that happens to be let at the market rent, even though yours is in better condition. That gap is not unfair. It is the contract you signed.

It also explains why a valuation may come in lower than a neighbour's recent sale, which owners often find hard to accept.

What to keep ready for a valuation

• The lease or leave and licence agreement itself.
• Rent currently received, and the escalation schedule.
• Remaining term and any lock in.
• Who pays taxes, maintenance and repairs.
• Deposit held, which is a liability not income.
• Payment history, if the tenant has been irregular.

Give these upfront. A valuer working without the lease is guessing at the most important input.
