Bulk leasing (sublease) is a structure in which owners entrust their apartment buildings or condominiums to a real estate company in a single arrangement, leaving property management and tenant response entirely to that company. While it can help avoid vacancy risk, there are also drawbacks that should be reviewed carefully.

How does bulk leasing differ from management outsourcing?

How bulk leasing works

A real estate company leases the entire property and then sublets it to tenants. The fee is 10〜20% of the rent, and the payment amount does not change even if there are vacancies or rent arrears. Property management and trouble handling are also included.

Difference from management outsourcing

Management outsourcing is a model in which only management operations and tenant recruitment are delegated. The owner signs the lease directly with the tenant, and the fee is lower at 3〜10% of the rent, but the owner bears the risks of vacancy and nonpayment.

What are the advantages and disadvantages of bulk leasing?

Advantages

  • Property management and complaint handling can be fully entrusted
  • Income is guaranteed even if there are vacancies or rent arrears
  • Long-term contracts of 10 years can provide more stable income

Disadvantages

  • Income may decline due to periodic rent reviews
  • You may not be able to track occupancy conditions
  • If no agreement is reached on a rent revision, there is a risk of contract termination

What four points should be checked in a bulk leasing contract?

1. Review the contract terms carefully

Be sure to confirm the contract period, contract rent, frequency of rent reviews, and renewal conditions.

2. Validity of the business plan

Review whether the income and expense plan is realistic and supported by clear grounds. Using a second opinion can also be effective.

3. Rules on restoration and repair costs

It is important to clarify in advance the cost rules and the requirement to present an estimate before any charges are incurred.

4. Brokerage capability and approach to information disclosure

Check whether the company will disclose tenant information, and choose a management company with strong leasing capability.

Frequently asked questions (FAQ)

Q. Is the rent guarantee in bulk leasing permanent?

No. In general, rents are reviewed every two years, and the guaranteed amount may be reduced depending on building age and market conditions.

Q. Can a bulk leasing contract be terminated midterm?

In most cases, termination by the owner is subject to conditions. Those termination terms should be confirmed before signing the contract.

Q. Which is better, bulk leasing or management outsourcing?

The better choice depends on the property location, vacancy risk, and the owner's tolerance for management burden. It should be assessed comprehensively.
