The objective is to minimize risks and make the investment worthwhile and problem-free.

Lease agreements on a commercial property are one of the key sources of income for the asset. A proper review of ongoing contracts is necessary to ascertain the cash position of the property. Have a look at the following points:

  • Payment record and delinquency: Verify if tenants have consistently paid on time.
  • Occupancy level: A high vacancy rate may indicate structural or locational problems with the property.

  • Structure and foundation: Look for damage, cracks, or foundation problems that could necessitate expensive repairs.
  • HVAC system (heating, ventilation, air conditioning): Examine its usage, age, and maintenance cost.
  • Electric and plumbing networks: Check if they are compliant with regulations and functioning properly.
  • Safety and accessibility code compliance: State that the building meets fire safety protocols, ADA-accessibility requirements (in the US), and all other regulatory stipulations.

  • Rental income: Check current income against market rates to determine if it’s as anticipated.
  • Operating costs: Consider ongoing costs such as maintenance, insurance, taxes, and property management fees.
  • Tax history and liabilities: Verify if there are any outstanding tax debts or if there are any changes in tax rates that will affect profitability.
  • Profitability projections and market value: Consider trends in the market and the future appreciation of the property.

4. Regulatory Compliance and Legal Requirements

Non-compliance with regulations can result in exorbitant expenses in the form of fines or render the property useless for its intended use. The process of due diligence should include:

  • Zoning and land use: See that the planned use of the property is according to local ordinance.
  • Environmental impact: Determine possible soil contamination or environmental problems needing to be remediated.
  • Permits and licenses: Ensure the property is entitled to all the permits it needs for its utilization.

5. Legal Due Diligence

A legal inspection of the property guarantees that legal problems that can hamper the investment in the future are evaded. It is wise to investigate:

  • Title deeds and liens: Verify that the property boasts a clear title with no litigation or debts against it.
  • Restrictions or easements: Determine if there are limitations on use that can affect the development of the property.
  • Outstanding lawsuits or disputes: Assess if there are suits against the property or tenants.

Importance of Due Diligence Checklist

Given the enormous volume of information that needs to be reviewed in a commercial real estate transaction, it is strongly advisable that a due diligence checklist is used to help investors coordinate every aspect of the review. This reduces the chances of overlooking crucial details and enables effective decision-making.
