"I want to buy a house, but I don't know where to start" is a feeling a lot of first-time buyers share. Buying a home is one of the biggest purchases most people will ever make, and knowing the right sequence of steps is what makes the process go smoothly. This article walks through the correct steps for buying a house, the things to watch out for along the way, and the best timing for a purchase in plain, practical terms.

How Do You Buy a House? A 6-Step Overview

Buying a home breaks down into six steps. Understanding the full sequence up front makes it much easier to make good decisions at each stage.

Step 1: Work Out Your Financing

The first thing to figure out is your budget and how much you can realistically borrow on a mortgage. As a general rule of thumb in Japan, lenders tend to approve loan amounts of roughly six times annual income (so an annual income of 8 million yen typically supports borrowing around 48 million yen). A down payment of 10-20% of the purchase price is a common benchmark, but zero-down mortgages have also become mainstream, so putting nothing down up front is a realistic option for many buyers.

Step 2: Sort Out What You Actually Need

Work through your must-haves: floor plan, commute distance, school district, parking, and so on. To avoid regrets later, it's worth getting every member of the household's opinion before you start looking. Rank your priorities and split them clearly into "non-negotiable" and "nice to have but flexible."

Step 3: Gather Information

Pull information from multiple channels — property portal sites, real estate agency branches, and print listings. The trick is to narrow the field roughly by area, budget, and floor plan first, so you keep a healthy number of options on the table rather than fixating on one listing too early.

Step 4: Tour and Narrow Down Properties

Once you've shortlisted candidates, go and see them in person. Photos won't show you everything, so check carefully for cracks or warping in the walls, where outlets are placed, mold around plumbing fixtures, and the surrounding environment (noise levels, distance to the nearest supermarket).

Step 5: Sign the Sale and Purchase Agreement

Once you've found a property you like, you move into contract negotiations with the seller. Negotiating the price down is completely normal in Japan, and in many cases the seller has already priced the listing with some room for negotiation built in. Signing the contract requires your registered personal seal (jitsuin), a certificate proving that seal is registered (inkan shomeisho), and identity documents. Cancelling after signing generally means forfeiting your deposit as a penalty, so read everything carefully before you sign.

Step 6: Handover

Handover typically happens about a month after the contract is signed. You'll need your registered seal, a residence certificate (juminhyo), identity documents, and funds to cover final prorated adjustments (for things like property tax and management fees).

Two Big Things to Watch Out for When Buying a House

1. Think It Through Thoroughly Before You Sign

Cancelling after the contract is signed is difficult and triggers a penalty. If you're buying a previously owned home, getting a home inspection (a professional structural and condition survey, typically costing around 60,000 yen) before you sign lets you understand the true condition of the property in detail.

2. Be Ready for the Mortgage Screening Process

If your loan application is turned down after you've already signed, you risk losing your deposit and facing a cancellation penalty. The key is to apply for an amount that genuinely matches your income, and to go into the screening process with no missed payments or outstanding debt on your record.

When Is the Best Time to Buy a House?

The right timing varies by household, but statistically, marriage, having a child, or a child starting kindergarten or school are common triggers for buying. If you're planning to take out a mortgage, your 40s are roughly the last realistic point at which you can still qualify for a long repayment term, which is why buying by your 40s tends to be the practical cutoff. It's also increasingly common for couples to buy a barrier-free home for just the two of them once their children have grown up and moved out.

Frequently Asked Questions (FAQ)

Q. How much should I set aside for a down payment?
A. A common benchmark is 10-20% of the property price. For a 30-million-yen property, that works out to roughly 3-6 million yen, though zero-down mortgages are now widely available as well.
Q. How much can I actually borrow on a mortgage?
A. A common approval benchmark is around six times annual income. That said, the actual amount you can borrow depends on the specific lender, your employment type, and your debt-to-income ratio, among other factors.
Q. Is a home inspection required when buying a previously owned house?
A. It isn't legally required, but for a cost of around 60,000 yen, a professional inspector can give you a detailed assessment of the structure and building systems, so it's strongly recommended.
Q. What should I pay special attention to during a property viewing?
A. Key things to check include cracks or warping in the walls, the placement of electrical outlets, mold around plumbing fixtures, noise from neighbouring properties, and the distance to the nearest supermarket or school.
