When real estate agents bring up due diligence, they usually mean the buyer’s research prior to making an offer or the contingency period before the final closing.
Real estate due diligence includes reviewing documents, financial calculations, and evaluating risks. This can be a complicated process that requires security. With the rise of data rooms, all parties of the RE deal can now manage and share critical documents securely and efficiently.
Understanding the due diligence process, how it’s done, and common pitfalls helps minimize risks in real estate. In this article, we elaborate on the due diligence process, how to use data rooms to simplify a due diligence period in real estate, and share a real estate due diligence checklist to help real estate investors stay organized.

What is due diligence in real estate?

Property due diligence starts when the buyer and seller accept the Purchase and Sale Agreement (PSA) and the buyer makes contractual deposits. This period takes up to 90 days. During this time, the buyer collects detailed information about the property values to make an informed decision whether or not to buy the object.

The key stakeholders involved in the real estate due diligence are:

  • buyers, who need to make sure the property is a sound investment;
  • sellers, who must provide transparent and accurate information about the object they sell;
  • legal experts, who review titles, contracts, and compliance with laws;
  • financial advisors, who analyze if the property is a valuable investment with potential returns.

Each stakeholder plays a critical part in the deal. Their smooth collaboration helps avoid costly mistakes and mitigate common due diligence risks.

Common risks associated with inadequate real estate due diligence

With adequately performed due diligence, you can be sure that your real estate investment will be profitable and the purchase process will go without any complications. Going through the property inspection checklist can act as a guide to making a smart and worthy investment.

On the other hand, if you neglect the due diligence process, you can face a lot of risks. These are the major pitfalls of poor real estate due diligence highlighted in this post from the BLEW. Inc, surveying, engineering, and environmental firm:

For instance, you can buy a property that is not ADA-compliant, has unpaid taxes, or can’t be used as planned due to zoning rules. These issues could have been indicated if you checked property titles, zoning laws, and land due diligence.

Environmental risks

Environmental site assessments play an integral role in establishing the functionality and status of a real estate investment. A properly performed ESA indicates potential contaminants in or under the property’s foundation, as well as investigating a property’s past and present environmental conditions. The impact of discounting environmental compliance bears a heavier burden: extensive site cleanup costs, regulation consequences, and environmental contamination.

Ignoring due diligence or conducting it without a structured plan can negatively affect finances and an investor’s reputation. Additionally, it can unintentionally harm the environment. Is it worth the risk? Probably, it is not. The real estate due diligence checklist we share in the next chapter will help you mitigate the risks and make sure the property is worth an investment.

Benefits of using a due diligence data room for real estate due diligence

Real estate acquisition is a complex, multi-step activity that can take months of your precious time. The due diligence checklist shared above can make this process more streamlined, however, managing such a vast amount of data requires secure online storage for investors and sellers to collaborate.

JLL’s 2023 Global Real Estate Technology Survey indicated that more than 80% of respondents (both occupiers and RE investors) are going to increase their technology budgets in recent years. Over 90% of them are ready to pay extra for a secure tech-enabled space. Virtual data rooms for due diligence can enhance this discovery stage. Here are some of the benefits you can expect.

Secure data storage

Security breaches jeopardize sensitive information and cause financial losses. One such breach happened back in 2023 when 1.5 billion records leaked in Real Estate Wealth Network data breach. 

The exposed database contained records about personal property history, motivated sellers, bankruptcy, divorce, tax liens, home owner association (HOA) liens, inheritance, vacant properties, and more. The folders also contained information on property owners, sellers, and investors. This costly mistake could potentially lead to other fraudulent activities like social engineering, phishing attacks, property & mortgage fraud, and more.

Virtual data rooms help to store data securely. Features like encryption protocols and access controls offer multiple layers of protection to safeguard confidential data. To minimize risks of data leaks or unauthorized access, data room administrators monitor user activity and address atypical activities.

Easy document sharing

Centralized document management is one of the main benefits of data rooms for real estate due diligence. Unlike traditional data rooms that are basically physical document storage, all data can be securely stored online. This means less paperwork and better accessibility for both private property and CRE due diligence.

On top of that, there is no need for physical meetings as all updates and discussions happen in real time within a secure online space. Q&A sections and audit trails feature ensure transparency and accountability throughout the due diligence process.

Compliance with regulations

Compliance with regulatory standards is non-negotiable in real estate transactions. All the top data room providers offer top-notch security features that comply with regulatory standards. When you conduct a due diligence process with a data room, you can rest assured your data is handled according to current industry laws and regulations.

How to organize real estate due diligence documents in a data room

Common mistakes to avoid in real estate due diligence

The real estate due diligence checklist we shared earlier is a critical component of the deal preparation. However, if you do not know the nitty-gritty of the due diligence procedure, it can be easy to make costly mistakes. Here, we look into the common pitfalls of real estate due diligence and share some tips to avoid them. Lacayo Law Firm, for example, identifies the following problems:

Overlooking hidden liabilities and legal encumbrances

Oftentimes, buyers do not apply for external legal support when doing the due diligence. This can lead to legal issues, loss of money, and reputational damage. No matter if you decide to invest in personal property or need to conduct commercial real estate due diligence, it’s recommended to apply for a qualified real estate attorney’s support to better understand the legal intricacies, guard your interests, and make sure everything complies with local regulations and laws.

Solely relying on seller-provided information

As a seasoned investor, never assume anything. Your goal is to uncover any problems or issues with the property. So, ask the seller hard questions and get answers in writing. Request copies of all financial statements to refer to them again later to make an informed decision.

Ignoring local zoning and development restrictions

Zoning restrictions regulate how a property can be used and developed. Before you sign up for a deal, you need to thoroughly inspect the local zoning laws to identify specific regulations that apply to the property you are investing in. This will help you discover if the property you are going to buy aligns with your intended use. If there are any restrictions that could hinder your plans, it is better to continue your property search.

Failing to verify financial and tax records thoroughly

There are many additional costs associated with owning a property. Not all buyers take them into account when closing a deal. Property taxes, homeowners’ insurance, and maintenance costs are just a few of the additional expenses. To avoid overpaying, make sure you verify financial and tax records when you determine whether a property is within your budget.

Final thoughts

Real estate due diligence is a time and effort-consuming process. But it is an absolute necessity as a thorough investigation can help you avoid overpaying, buying property that doesn’t fit your needs, violating laws and regulations, and other hidden problems that can happen in the long term.

The due diligence checklist real estate template shared above is your guide to a mindful and in-depth property check. Conduct thorough legal, financial, and technical checks of the property. Do not forget about environmental assessment and market analysis. This due diligence checklist will help you navigate the complexities of real estate transactions with confidence.

And remember to use a due diligence data room for better document management and collaboration between stakeholders. A secure data room will help save time, reduce errors, and facilitate smoother transactions.
