What should I expect? 

During due diligence in real estate, you should expect a smooth process that will take about a month. Major problems do come up, but they are rare. In fact, more than 90% of real estate contracts go through and close. 

  • Inspection of the structure 
  • Financial information examination 
  • Title search 

Residential sales include these elements. Commercial and industrial transactions will include other, more complicated clauses as well. These may include a study of legal commitments, a review of management.


A due diligence checklist includes items that you should take care of at each stage of the sale. Since it is a complicated process, you should have your own idea about what items you need to take care of when. Depending on your situation you need to include different things, you may want to: 

  • Rent a residential property 
  • Buy a residential property  
  • Rent a commercial property 
  • Rent an industrial property 
  • Buy a commercial property 
  • Buy an industrial property 

Residential sales are the easiest types of transactions, so you should start by looking at a good residential checklist. Add appropriate topics according to the type of property you are interested in.1  

Due Diligence Clause 

A due diligence clause is a section of a contract that allows the buyer to ensure that there are no major problems with the property. Both residential and commercial contracts include these clauses, and they are important because:

  • They ensure the value of the property 
  • They allow for inspections for any hidden defects 

Buying a home is complicated, and these clauses help make sure that your investment is reasonable.2  

Is Due Diligence in Real Estate Required? 

Due diligence in real estate is not required, but we highly recommend that you take the time to learn the process and stay on top of each issue that arises. Never go into any large transaction blind. Make sure you always get as much information as you can about the home before you make an investment.  

Types of Due Diligence in Real Estate

Types of due diligence for residential properties protect you and your lender from making a bad deal. They include: 

  • Home inspection 
  • Title search 
  • Appraisal 
  • Financing 

These are standard in almost all residential real estate contracts. You may add a home sale contingency or other tests such as radon or mold inspections, which would be part of the home inspection. Commercial and industrial have much more involved clauses for management, financials, and structural issues.3  

When Due Diligence Ends 

After due diligence ends, the sale is pending. When you buy your home, the deal is almost done. Two groups still prepare paperwork for the closing: 

  • Mortgage company 
  • Title agency 

These finalize the paperwork with dates and other details, such as actually scheduling a closing date that all parties can attend. This usually takes a week or less.  

Buyer’s Due Diligence in Real Estate

Due diligence when buying a house is making sure you understand the process and executing each contingency efficiently so your house closes on time.  

  • Before you even start looking for a house make sure you understand the process in your area 
  • Find a competent realtor that you trust 
  • Vet your mortgage company. Really shop around and make sure you have the best deal for you 
  • Take the clauses in your contract seriously. Find competent professionals to help you with each clause 

There are usually four clauses in a typical residential contract, but you should be careful long before you sign a contract. You need to find a good agent and lender as soon as you begin your hunt for a new home. 

Seller Backs Out During Due Diligence 

A seller can back out during due diligence with a cause. The two main reasons are they can’t find another house, and they get a better offer. Sellers, though, must be careful because they may want to, but they must have cause to. Three ways a seller may cancel a contract are: 

  • Seller added a home sale contingency 
  • The buyer can’t adhere to the terms, such as securing a mortgage on time 
  • Buyer requests repairs the seller is unwilling to do 

A home sale contingency is by far the biggest deal killer from the seller’s side.  However, if the seller really wants to get out of the contract, they can disagree to deal with any issues with the home inspection. If the buyer really wants the house, though, they may agree to not seek any repairs.4
