Few things make house-hunting feel more intimidating than the wall of acronyms and shorthand that comes with it. Listings, agents and paperwork are full of terms like OTP, MOP, TOP and en bloc, tossed around as though everyone already knows them. Getting to grips with property jargon Singapore buyers keep meeting is one of the quickest ways to feel in control, because once the words make sense, the decisions behind them do too. This guide is a plain-English glossary of the terms you are most likely to encounter, grouped so you can find them, with a quick-reference table you can keep open while you read your documents.
Why the Jargon Matters
Property language is not there to confuse you, though it often feels that way. Each term is shorthand for a rule, a document or a stage in a transaction, and most of them carry real financial or legal weight. Mixing up leasehold and freehold, or misreading what MOP means for your resale plans, can shape a decision worth hundreds of thousands of dollars.
The aim here is understanding, not expertise. Knowing what a term means helps you ask the right questions, but the numbers, rates and eligibility rules attached to many of these words change often. Treat this glossary as general information, not financial or legal advice, and always confirm current figures and rules with the official source, whether that is HDB, URA, CPF Board, IRAS, MAS or the SLA.
Buying and Selling Terms
These are the words you meet from your first offer to the day you collect your keys. The Option to Purchase, or OTP, is a legal document in which a seller grants you the exclusive right to buy at an agreed price within a set period, in exchange for an option fee. To exercise the OTP is to sign and pay the deposit, turning the option into a firm contract. The Sale and Purchase Agreement, or SPA, is the fuller contract used for new launches.
Conveyancing is the legal work of transferring ownership, done by a conveyancing lawyer. A caveat is a notice your lawyer lodges to register your interest in the property. Completion is the final date when the balance is paid and ownership legally transfers. Vacant possession means the seller hands over the property empty and ready for you. Valuation is a professional estimate of a property’s worth, which matters because your loan is usually based on it.
HDB and Public Housing Terms
Public housing has its own vocabulary. BTO, or Build-To-Order, is HDB’s system for new flats built once enough buyers commit. A resale flat is an existing HDB flat bought from its current owner rather than from HDB. MOP, the Minimum Occupation Period, is the number of years you must live in your flat before you can sell it or rent it out in full; the exact period is set by HDB and should be checked with them.
An EC, or Executive Condominium, is a hybrid: it starts with HDB-style rules and eligibility, then becomes fully private after a set number of years. A grant is government support that helps eligible buyers with the cost of a flat, though amounts and income ceilings change and must be checked with HDB and the CPF Board. COV, or Cash-Over-Valuation, is any amount a resale buyer pays in cash above the flat’s valuation.
Money, Loan and Tax Terms
The financing side has the densest jargon, and it is worth slowing down for. LTV, the Loan-to-Value ratio, is the share of a property’s price or value that a bank will lend. TDSR, the Total Debt Servicing Ratio, and MSR, the Mortgage Servicing Ratio, are limits on how much of your income can go towards debt and mortgage repayments. All three are set by MAS or HDB, change over time, and must be checked at the current figure rather than assumed.
BSD is Buyer’s Stamp Duty, ABSD is Additional Buyer’s Stamp Duty, and SSD is Seller’s Stamp Duty; these are taxes administered by IRAS whose rates change, so always verify the current rate. CPF accrued interest is the interest you would have earned on CPF savings used for your home, which must be returned to your CPF account when you sell. In-principle approval is a bank’s non-binding indication of how much it may lend you.
A Quick-Reference Glossary
Keep this table handy while you read listings or paperwork. It gathers the most common terms in one place, in plain language. For any term tied to a figure or a rule, confirm the current detail with the relevant authority before you rely on it.

Terms Around Developments and Ownership
A few more words describe the property itself. TOP, the Temporary Occupation Permit, is the point at which a new development is safe and permitted to be occupied, often before every legal formality is finished. CSC, the Certificate of Statutory Completion, comes later and confirms the development fully meets requirements.
Freehold means ownership with no time limit, while leasehold means ownership for a fixed number of years, such as 99, after which it returns to the state. En bloc, or collective sale, is when the owners in a development agree together to sell the whole site, usually to a developer. URA is the Urban Redevelopment Authority, Singapore’s land-use planner, whose master plan shapes what can be built where. When any of these terms touches your own decision, read the specifics carefully and get professional help.
Using This Glossary Well
This glossary suits first-time buyers, renters becoming owners, and anyone who wants to read a listing or a contract without reaching for a search engine every other line. It is a starting point for understanding, not a substitute for advice, and it deliberately avoids quoting rates or amounts because those are exactly the details that change.
When a term carries money or legal consequences, go to the source: HDB and the CPF Board for public housing, eligibility and grants, IRAS for stamp duty and tax, MAS for loan rules, URA and the SLA for land and planning, and a conveyancing lawyer for your contracts. For agents, use a CEA-registered professional and check the CEA Public Register. Nothing here is financial or legal advice; it is general information to help you ask better questions.
