5 Common Mistakes First-Time Homebuyers Make in Singapore (And How to Avoid Them)
  1. Not budgeting for the full cost of buying a home. Many first-timers fixate on the property price and loan, but forget the hidden costs that add up. Besides your downpayment, remember to budget for Buyer’s Stamp Duty (which can be tens of thousands), legal/conveyancing fees, option fees, valuation fees, agent commissions (if any), and renovation costs. Skipping these in your planning can leave you cash-strapped later. How to avoid it: Make a checklist of all possible expenses. Use tools like Cashew’s Affordability Calculator to estimate not just your loan amount but also the cash/CPF needed upfront. Always keep a buffer of extra savings for unexpected expenses (like a higher renovation quote or temporary housing if your move-in is delayed).
  2. Overstretching your budget (taking the maximum loan). It’s tempting to buy the most expensive home the bank says you can afford, especially when you’re excited about a particular condo or location. But taking on the maximum loan allowed (up to the 75% LTV limit or your TDSR threshold) can be risky. You might end up “house poor,” with too much of your monthly income going into repayments, leaving little for emergencies or lifestyle needs. Interest rates can also rise, which would increase your monthly instalments if you chose a floating rate loan. How to avoid it: Base your budget on what monthly payment you’re comfortable with, not just the maximum the bank will lend. A common guideline is to keep total housing costs (mortgage, taxes, maintenance) under about 30-35% of your income for peace of mind. If the bank offers you a loan that breaches that comfort level, you don’t have to use the full amount. It’s perfectly okay (smart, even) to buy a slightly cheaper home and have financial breathing room. Use our calculators to run different scenarios (e.g., if interest rates climb from 2% to 4%) and see if you could still cope.
  3. Skipping mortgage pre-approval or HDB loan eligibility checks. Some buyers dive into home viewings and even commit to an Option to Purchase without firmly securing their financing. This can lead to nasty surprises – for example, finding out the bank will only lend you $450k when you need $500k, or discovering you’re not eligible for an HDB loan after paying the option fee. How to avoid it: Always get your financing sorted before you make an offer. If you’re going with a bank, get an Approval in Principle from the bank (or better yet, through Cashew we can obtain several for you from different banks to compare). If you plan on an HDB loan, apply for the HDB Flat Eligibility (HFE) letter early. These pre-approvals give you a clear cap and assure the seller you mean business. It also protects your option fee from being forfeited due to loan issues. Essentially, don’t sign anything or exchange money on a property until you know the funds are secured.
  4. Not comparing mortgage options (or just taking the default option). Another mistake is not doing your homework on home loans. First-time buyers might automatically take an HDB loan without considering if a bank loan could save them interest, or conversely, jump on a bank loan without realizing the HDB loan’s benefits (like no early repayment penalty and smaller downpayment in cash). Even among bank loans, there are dozens of packages – fixed rates, floating rates linked to SORA, different lock-in periods, etc. Going with the loan your current bank offers you, without comparison, might cost you thousands more in interest. How to avoid it: Shop around and compare. This is where an unbiased mortgage broker like Cashew is a lifesaver – we partner with all the major banks to present you with the best rates and terms in one place, for free. Within minutes, you can see if another bank offers a lower interest or a package with perks (legal fee subsidies, for example). If all that choice sounds overwhelming, you can also chat with our AI Mortgage Assistant or a human advisor who can explain the differences. The key is: treat your mortgage like any big purchase – explore your options before deciding.
  5. Letting emotions overpower due diligence. It’s easy to fall head over heels for a home – the renovated interior, the view, or the perfect location. But emotional attachment can lead to overlooking practical issues. Some buyers rush to seal the deal on a “dream home” without checking critical details like the remaining lease on a 40-year-old HDB flat (which can affect future resale value and loan limits), or whether that lovely balcony view will be obstructed by a new development in two years. Others might skip a professional home inspection (for landed properties) or ignore signs of maintenance problems because they’re in love with the place. How to avoid it: Take a step back and do your due diligence. For HDB flats, verify the lease details and consider how it aligns with your long-term plans (will the flat be at least 95 years remaining if you intend to pass it to your kids, for example?). For any property, check recent transaction prices (so you don’t overpay), inspect the unit thoroughly (look for water damage, ask about any renovations or repairs needed), and read the surroundings – are there en bloc plans, construction upcoming, etc.? It helps to have a rational second opinion: bring along a trusted friend or enlist a qualified agent who will point out red flags. And remember, there will always be other houses if one doesn’t work out. It’s better to lose out on an offer than to end up with buyer’s remorse.

In summary, being a first-time homebuyer in Singapore is a learning process. You can avoid most of these mistakes by educating yourself (since you’re reading this, you’re on the right track!), planning your finances carefully, and leveraging the right resources. Cashew is here to support you at every step – from budgeting tools to unbiased loan comparisons and expert advice. Learn from common mistakes, plan well, and you’ll be well on your way to a successful and rewarding first home purchase. Keep calm and happy home hunting!
