Property Viewing Checklist for Singapore Buyers and Renters

A property viewing in Singapore is best treated as a structured inspection rather than a walk-through: the buyer confirms eligibility and budget beforehand, records defects, noise, layout and lease facts during the visit, and checks the asking price against transaction data afterwards. This checklist follows that sequence for HDB resale flats, private resale condominiums and developer show flats, and it flags the points at which the Option to Purchase (OTP) turns a viewing into a binding commitment.

TL;DR

• Before any viewing, obtain an HDB Flat Eligibility (HFE) letter for an HDB flat or an Approval-in-Principle (AIP) for private property, and set a budget ceiling that survives the Total Debt Servicing Ratio (TDSR) test.
• During the viewing, inspect water pressure, drainage, ceilings, walls, windows, noise, orientation and any renovation works, and photograph everything with a timestamp.
• Singapore operates on a caveat emptor basis, so verbal assurances from an agent or seller do not replace checks through official channels.
• After the viewing, compare the asking price with recent transactions in the same block or project, and read the OTP terms before paying any option fee.
• Show flats illustrate unit types and do not guarantee an exact replica of the unit being sold, so the approved plans and written notices at the site take precedence.

Before the viewing: eligibility, budget and research

The most common error in Singapore house-hunting is viewing units that the buyer cannot yet legally or financially purchase. Two documents set the boundary. For an HDB flat, the Council for Estate Agencies directs buyers to obtain an HDB Flat Eligibility (HFE) letter through My Flat Dashboard before making housing and financing decisions. For private property, the equivalent is an Approval-in-Principle from a financial institution, which indicates how much the lender is prepared to extend.

Confirm the loan ceiling

The loan ceiling is not simply a multiple of income. Banks incorporate an interest rate floor into the TDSR calculation, as the Monetary Authority of Singapore noted in a written parliamentary reply on rising rates and mortgage repayments. A flat that fits the headline budget may therefore fail the stress-tested figure. The worked examples in Know Your Loan Ceiling: MSR and TDSR show how the two ratios interact for HDB and private buyers, and the five-step mortgage affordability check sets out the order in which the figures should be assembled.

A budget check should also cover the cash portion of the purchase. LTV limits in Singapore explain why even buyers who need little financing still have a minimum cash requirement. Buyers who already own a residential property should review the ABSD and TDSR checks for a second property before shortlisting anything, since the additional tax can change which units are worth viewing at all. For a quick sense of whether a monthly commitment leaves enough room for other spending, a house poor affordability calculator offers a general cross-check, though it is no substitute for a bank's own assessment.

HDB buyers should additionally check which grants apply, because grant amounts affect the realistic price band. The page on HDB grants in 2026 summarises amounts, eligibility and how they stack.

Research the unit before arriving

Before the appointment, the following can be established from a desk:

1. Recent transaction prices for the same block or project, ideally for the same flat type and a similar floor range.
2. The remaining lease, which affects both financing and resale value.
3. The URA Master Plan zoning around the property, since the CEA guidance cited by practitioners points buyers to the Master Plan for future developments rather than to verbal descriptions.
4. The floor plan, which should be read before the visit. The guide to floor plan reading and four wall symbols helps identify structural walls, which cannot be hacked, and service areas such as the bomb shelter.

For condominiums, the haio transaction pages show price history by project, for example CityVale, D'Mira and Casa Riviera, which allows an asking price to be placed against what comparable units actually sold for.

What to bring to a viewing

A short kit makes records comparable across viewings:

• A phone with a flashlight, for under-sink cabinets, ceiling corners and the inside of wardrobes.
• A tape measure or laser measure, because room dimensions quoted in listings are often approximate.
• A phone charger or small plug tester, to confirm that sockets work.
• A printed or digital scoring sheet with the same rows for every unit, so that a third or fourth viewing can be compared with the first.
• The floor plan and a note of the asking price, the remaining lease and the transaction range for similar units.

Where possible, visit at two different times, for instance a weekday evening and a weekend morning. Noise from traffic, construction, neighbours, void decks, hawker centres or schools varies considerably between those periods, and a single mid-day visit can understate it.

Exterior, building and surroundings

The inspection begins before the front door is opened. Observations outside the unit often matter more than finishes inside it, because they cannot be changed by the owner.

For condominiums, note the facilities and their upkeep, and ask about the maintenance fee and any recent or planned special levies. For HDB flats, check the corridor privacy: units opposite lift lobbies, stairwells or rubbish chutes are common sources of complaints.

Inside the unit: room-by-room inspection

The Home & Decor Singapore defects guide lists built-in carpentry, appliances, water pressure, drainage speed, sewer odour and holes in walls among the points to examine. The sequence below expands those into a route that can be followed in about forty-five minutes.

Entrance, living and dining areas

• Open and close the main door, gate and every window. Check that locks, hinges and grilles operate smoothly.
• Look at the ceiling for water stains, discolouration or fresh patches of paint that may conceal previous leaks.
• Inspect the floor for hollow-sounding tiles (tap with a knuckle or coin), cracks and uneven levels.
• Switch on every light and test every socket and air-conditioning unit, noting the age of the compressors.
• Stand still for a minute with windows closed and then open, and listen.

Kitchen

• Run the tap at full flow and check pressure, then fill the sink and watch how quickly it drains.
• Open every cabinet and look beneath the sink for dampness, mould or corroded pipes.
• Check the hob, hood and any included appliances, and confirm in writing which of them remain with the unit.
• Note ventilation: a kitchen with poor airflow retains cooking odours and humidity.

Bathrooms and household shelter

• Flush the toilet, run the shower and check water pressure and temperature response.
• Look at the grout and silicone around the bathtub or shower for blackening or gaps, and at the ceiling below any bathroom above for staining.
• Smell the floor trap and drains. A persistent sewer odour can indicate a dry trap or a deeper plumbing issue.
• In HDB flats, locate the household shelter and note how it has been used, since its structure cannot be altered.

Bedrooms, balcony and utility spaces

• Measure the rooms and compare with the floor plan, and check whether built-in wardrobes are fixed or movable.
• Inspect the corners of exterior walls and behind furniture for mould or seepage, especially on lower floors and in units facing prevailing rain.
• Check balcony or yard drainage, waterproofing and any signs of ponding.
• Look at the window frames and seals for rust, gaps and rain staining.

Renovations and unauthorised works

Renovation history deserves its own step, because the buyer inherits the consequences. Under the caveat emptor principle that governs Singapore property transactions, the buyer assumes responsibility for any unauthorised works discovered after purchase, regardless of whether the seller disclosed them. The HDB resale procedures state that the HDB Branch inspection exists to check for unauthorised renovation works that may damage the common property or other flats, or affect the structural stability of the building. Sellers of HDB flats must regularise or remove such works before the transaction completes, but a buyer who notices doubtful alterations during the viewing is better placed to raise them before committing.

Points to look for at the viewing include:

• Walls that appear to have been removed, shifted or newly built, compared with the floor plan.
• Changes to the bathroom or kitchen layout, enlarged openings or altered windows.
• Floor finishes that have been raised or hacked, and any visible alterations to the main door or gate.
• Wiring that appears to have been extended or relocated without a clear distribution board.

For anything uncertain, a qualified person such as a building surveyor can verify compliance before the Option to Purchase is exercised, as HDB-related guidance notes. Verbal assurances about past works are not a substitute for documentation.

Show flats and new launches

A developer show flat requires a different mindset, since the unit on display is not the unit being purchased. The URA Home Buyers' Guide advises buyers to review the information on the project and the specific unit carefully before committing, and notes that developers must ensure the displayed plans, models and show units are accurate. In practice, show units are meant to illustrate unit types and not to guarantee an exact replica. Where a show unit has had a wall removed or otherwise altered, the location, thickness and width of the change should be clearly labelled.

At a show flat, the checklist narrows to:

1. Compare the show unit layout with the approved plan of the unit being considered, including its floor level and orientation.
2. Ask for the schedule of finishes, fittings and appliances in writing, and note which items in the show unit are not included.
3. Look at the site plan to establish the position of the unit relative to the entrance, lifts, facilities, neighbouring developments and any noise sources.
4. Check the payment schedule and the expected completion timeline against the financing plan.
5. Leave with the written notices and brochures, not just impressions.

Because the unit does not yet exist, the viewing cannot test noise, view or light directly. A visit to the actual site, at different times of day, supplements the show flat.

Rental viewings

Tenants share most of the interior checks with buyers but face a different set of risks, mainly around inventory and deposit disputes. The following apply in particular:

• Photograph all existing damage on the day of the viewing or key collection, and attach the images to the inventory list.
• Confirm which furniture and appliances are included, and who is responsible for servicing air-conditioning units.
• Check the lease length, the diplomatic or early-termination clause if any, and the stated rules on subletting and visitors.
• Compare the asking rent with recent rental transactions in the same building before negotiating.

Questions to ask the agent or owner

The questions below are aimed at facts that can be verified, since the burden of due diligence sits with the buyer.

• Why is the owner selling or renting, and how long has the unit been on the market?
• What renovation was done, when, and are the permits available?
• Has there been any water seepage, pest issue or dispute with neighbours?
• What are the monthly maintenance fee and any outstanding or announced special levies?
• What is the remaining lease, and what is included in the sale (furniture, air-conditioning, appliances)?
• For HDB resale: has the seller registered an Intent to Sell, and when?

Answers should be recorded and, where material, confirmed in writing.

After the viewing: price check and the Option to Purchase

The viewing ends with a comparison, not an offer. Score each unit against the same criteria, then place the asking price beside recent transactions for comparable units. If the ask sits materially above the recent range, the gap is a negotiating point or a reason to walk away.

Once a buyer wishes to proceed, the Option to Purchase becomes the central document. According to the HDB, the Option to Purchase expires 21 calendar days from the option day, including weekends and public holidays. The OTP important notes state that sellers must have a valid Intent to Sell registered in the HDB Flat Portal at least seven days before granting an OTP, and that the Intent to Sell must remain valid when the resale application is submitted. The buyer needs a valid HFE letter at the time the OTP is granted. Terms that depart from the HDB-prescribed form, such as side agreements, are not enforceable.

The option fee is capped at S$1,000 and the deposit (option fee plus option exercise fee) at S$5,000, as set out in the HDB's published OTP terms. Because the OTP is a binding contract, any structural or renovation concern identified at the viewing should be resolved, or a surveyor engaged, before the buyer exercises it.

Our perspective: why a viewing needs data

A viewing captures how a property feels, and that is only half of the decision. At haio, the working premise is that the other half is data: transaction history, valuation, affordability and market direction, all of which can be checked before anyone walks through a door. Singapore's caveat emptor framework places responsibility on the buyer, and a buyer who arrives with a verified budget and a transaction range is less dependent on the seller's or agent's characterisation of what is a fair price.

We also see a recurring pattern: viewers evaluate the interior carefully and the price loosely. The reverse order serves buyers better. Establish the loan ceiling, learn what comparable units have sold for, then use the viewing to confirm the physical condition that justifies, or fails to justify, the asking price. Interest rates add a further reason for discipline. As we discuss in our mortgage rate forecast and the comparison of fixed and floating home loans, the repayment on a given loan can move over the holding period, and the affordability test should reflect that.

For investors, the viewing checklist should be paired with an underwriting routine; the 15 minute underwriting checklist for property investors sets out the figures to hold alongside the physical inspection.

— HAIO

Using haio before and after a viewing

The free tools on haio cover the preparatory steps described above: the Affordability page tests a purchase budget, Property Analysis places a unit within its market context, and haio's List assembles listings alongside data. Buyers who want valuation reports and deeper analytics can review haio+, published at S$49 per month or S$499 per year.

A one-page scoring sheet

To keep viewings comparable, a simple sheet with the following rows, each scored from 1 to 5 with a short note, is sufficient:

A total score is less informative than the row-level notes. A unit that scores well overall but fails on renovation compliance, for example, should be treated differently from one with minor cosmetic issues.

FAQ

What should I look out for when viewing a flat in Singapore?

Check for water stains on ceilings, hollow floor tiles, water pressure, drainage speed, sewer odour, window and door operation, and signs of mould on exterior walls. Also compare the layout with the floor plan to spot altered walls or unauthorised works, and note noise levels at different times of day.

What documents do I need before viewing a resale property?

For an HDB flat, a valid HFE letter is required before an OTP can be granted, so it is sensible to obtain it before viewing seriously. For private property, an Approval-in-Principle from a bank shows the likely loan amount. Both help establish which units are realistically within reach.

How long is an Option to Purchase valid for an HDB resale flat?

The HDB-prescribed OTP is valid for 21 calendar days from the option day, including weekends and public holidays. The seller must also have registered an Intent to Sell at least seven days before granting it. Any private agreement that departs from the prescribed terms is not enforceable.

Can I rely on the show flat to know what my unit will look like?

Not entirely. Show units illustrate unit types and are not a guarantee of an exact replica. Review the approved plans, the schedule of finishes and the written notices at the site to confirm what is included in the specific unit.
