When considering the purchase of a newly built condominium, it is important to understand its advantages and disadvantages accurately in comparison with a pre-owned condominium. This article explains the key strengths unique to new condominiums and the points that require careful attention.

What are the advantages of a newly built condominium?

The main advantages of buying a newly built condominium are threefold: up-to-date facilities, repairs for issues found during inspection, and stronger protection under non-conformity liability.

The facilities are up to date

Modern residential features such as floor heating, dishwashers, and high-speed internet lines are already in place. The newness of these facilities directly affects ease of living and comfort, and it can also help reduce renovation costs over the long term.

Any issues found during inspection can be repaired

During the pre-handover inspection (completion inspection), you can check for scratches, stains, and equipment defects and have them repaired before the property is handed over. Because pre-owned condominiums are generally delivered as-is, this is a major advantage of newly built properties.

Non-conformity liability is more comprehensive

Because the seller of a newly built condominium is a real estate company, the main structural components (foundation, columns, walls, roof, and so on) are legally required to carry a 10-year quality warranty. In private transactions involving pre-owned condominiums, the warranty period is usually much shorter, typically around six months to two years, so the level of reassurance differs significantly.

What are the disadvantages of a newly built condominium?

The biggest disadvantage of a newly built condominium is that it is more expensive than a pre-owned condominium. The main reasons for the higher price are as follows.

  • Sales costs such as model rooms, advertising, and labor are added to the property price
  • Real estate companies generally have a larger profit margin than brokers handling pre-owned condominiums
  • The value is elevated immediately after completion as a "new-build premium" (and asset value may decline by the time of handover)

New vs. pre-owned condominium: which should you choose?

The right choice depends on your objective. If you prioritize long-term residence and quality, a newly built condominium is often the better fit, while a pre-owned condominium is commonly the better standard if you prioritize cost performance and location. If your goal is investment, pre-owned condominiums often have an advantage from the standpoint of income yield.

Frequently Asked Questions (FAQ)

Q. How large is the price gap between a newly built condominium and a pre-owned condominium?

A. It varies by area and building age, but for properties in the same location and of similar size, newly built condominiums are commonly about 20% to 40% more expensive. With relatively new pre-owned units (5 to 10 years old), you may benefit from the price difference while still getting facilities that are nearly equivalent to new.

Q. What does the 10-year warranty for a newly built condominium cover?

A. Under Japan's Housing Quality Assurance Act, it covers the main structural components such as the foundation, columns, walls, and roof, as well as the parts that prevent rainwater intrusion. Facilities and interior finishes are not automatically covered, so they should be checked separately.

Q. What should be checked at the inspection of a newly built condominium?

A. Ideally, you should review scratches, stains, and warping on walls, floors, and ceilings; how doors and fittings open and close; the operation of water-related equipment; the position and function of outlets and switches; and the finish quality of storage spaces together with a specialist such as a home inspector.

Q. What is the new-build premium?

A. It refers to the brand and novelty value added to the price when the property is sold as new, and it is common for the resale price in the pre-owned market immediately after handover to be lower than the original purchase price. For investment aimed at resale, your return calculations should take into account the disappearance of this "new-build premium."
