A plain-language glossary of housing terms

Definitions of the terms used across this site

Every term below is used somewhere else on this site. Definitions are general and describe ordinary usage rather than any statutory definition.

Achieved price
The amount actually paid at completion, after any renegotiation. The only price that is evidence of what a market did.
Affordability assessment
A lender's evaluation of whether repayments are sustainable, including a stress test at a higher rate than the one being offered.
Agreed price
The figure accepted when a sale goes under offer. In most of the UK it is not binding until contracts are exchanged.
Arrangement fee
A lender's charge for setting up a loan, payable up front or added to the balance, in which case interest is paid on it for the term.
Asking price
The advertised figure. A marketing decision rather than a valuation.
Backland development
New housing built on the rear part of deep existing plots, usually reached by a side access.
Boundary
The physical or legal edge of a property. Registered plans show general position, not precise legal lines.
Break-even horizon
The length of stay at which the unrecoverable costs of buying and selling are outweighed by the saving against renting.
Building line
The consistent distance from the street at which the fronts of buildings sit along a stretch of road.
Building regulations approval
Confirmation that work met construction standards. Distinct from planning permission, and frequently the missing document in a transaction.

The most detailed buyer survey, covering construction, defects, their causes and likely remedies. Suited to older or altered buildings.
Capital
The amount borrowed, as distinct from the interest charged on it.
Chain
A sequence of linked transactions in which each purchase depends on a sale. The main source of fragility in residential transactions.
Chain-free
A buyer whose purchase does not depend on selling a property, or a seller with no onward purchase.

Condition report
The lightest form of buyer survey, giving element-by-element gradings without detailed advice or, usually, a valuation.
Conservation area
A designated area where additional controls apply to demolition, alteration and trees.
Contract
The agreement for sale. Until it is exchanged, either party may withdraw without liability in most of the UK.
Conveyancing
The legal work of transferring ownership, covering title, searches, enquiries and completion.
Covenant
A promise attached to land that restricts or requires something, binding on later owners.
Deposit
The buyer's own contribution to the purchase price, and separately the sum paid on exchange of contracts.

A right over someone else's land, such as a right of way or a right to run services beneath it.
Early repayment charge
A fee for repaying a loan, in whole or part, during a fixed or discounted period.
Environmental search
A desk-based assessment of contamination, flood, ground stability and landfill risk. Not a site inspection.

Fixed rate
A mortgage rate held constant for an agreed initial period, after which the loan reverts to a variable rate.

Frontage
The width of a plot along the street. A primary determinant of density and of what a plot cost to develop.
Gazumping
A seller accepting a higher offer after agreeing a sale but before exchange, which the absence of a binding agreement permits.

Homebuyer survey
A mid-level inspection of visible and accessible parts, with gradings and commentary, often including a valuation.
Illiquidity
The property of an asset that cannot be sold quickly or cheaply. A defining feature of housing.
Indemnity policy
Insurance used to cover a defined legal risk, such as a missing consent, rather than resolving the underlying issue.
Infill
New building within an already developed area, on gaps, garden land or redundant sites.
Interest-only
A loan on which no capital is repaid during the term, leaving the full balance outstanding at the end.
Leasehold
Ownership of a property for a fixed term under a lease, with obligations to a freeholder.
Lender's valuation
An inspection commissioned by the lender to confirm the property is adequate security. Not a condition survey for the buyer.
