The Complete HDB Buying Guide for Singapore Homeowners

Understanding Your Eligibility

Before you start flat-hunting, confirm your HDB eligibility. Singapore Citizens (SCs) aged 21 and above can purchase any HDB flat. Permanent Residents (PRs) can only buy resale flats and must be part of a family nucleus with another PR or SC.

First-timer households enjoy priority schemes including the Additional CPF Housing Grant (AHG) of up to $80,000, Enhanced CPF Housing Grant (EHG) of up to $120,000, and Proximity Housing Grant (PHG) of up to $30,000 when living near parents or children.

If you own private property locally or overseas, you must dispose of it within six months after completing an HDB resale purchase under the revised wait-out policy effective July 2026.

BTO vs Resale: Making the Right Choice

Build-To-Order (BTO) flats are priced below market rates and come with generous grants, but waiting times can stretch to 4+ years for popular projects. If you need housing sooner or want an established neighbourhood, resale may be preferable.

Resale flats offer immediate occupancy and mature amenities, but prices reflect market conditions. A four-room resale flat in a prime location could cost $600,000–$900,000 depending on remaining lease and condition.

Consider your life stage: young couples starting out may benefit from BTO affordability, while families needing space near good schools often find value in mature estates.

Financing Your HDB Purchase

HDB Concessionary Loans offer interest at 2.6% (0.1% above CPF OA rate) with up to 75% loan-to-value (LTV). Bank loans may offer lower initial rates but carry higher risk of rate fluctuations and require stricter credit assessments.

Use your CPF Ordinary Account savings for downpayment — at least 10% for HDB loans (20% for bank loans), with the remainder payable in cash. Factor in stamp duties: BSD is calculated on the purchase price or market value, whichever is higher.

The Mortgage Servicing Ratio (MSR) caps monthly loan repayments at 30% of gross monthly income for HDB loans. Bank loans follow Total Debt Servicing Ratio (TDSR) at 55%.

Grants You Should Know About

Enhanced CPF Housing Grant (EHG): Up to $120,000 for first-timer families purchasing resale flats. Income ceiling is $14,000 for households, $7,000 for singles.

Proximity Housing Grant (PHG): Up to $30,000 when buying a resale flat within 4km of parents' or married child's residence. Increased to $40,000 for extended proximity grants.

Family Grant ($50,000) and Singles Grant ($25,000) supplement the EHG. These are not stackable — you receive the higher applicable amount based on your profile.

CPF Housing Top-Up Grant helps couples where one party has insufficient CPF by allowing top-ups from the other spouse's account, subject to conditions.

Step 7: Second appointment — collect keys and begin renovation planning

Hidden Costs Buyers Overlook

Stamp duties alone can add $24,600–$60,000+ to your upfront costs depending on property value. Budget 3-5% of purchase price for legal fees, valuation fees, and miscellaneous charges.

Renovation costs average $30,000–$80,000 for a typical four-room flat. Factor in ID consultation, materials, and potential delays.

Monthly conservancy and service charges range from $26.50–$116 depending on flat type. Property tax applies annually based on annual value assessment.
