The Ultimate Guide To Calculating ROI On A Fix And Flip Rehab Investment Property

Before you venture into any investment, it’s wise to do your due diligence. If you’re thinking of purchasing an investment property, it’s important to not only calculate your potential ROI before you invest, but also be aware of the traps into which many investors fall.

Here’s The Ultimate Guide To Calculating ROI On A Fix And Flip Rehab Investment Property

Before any finer calculations begin, there is some quick math every investor can perform to decide if a property is even worth looking at further.

Step 1: Know your targeted sale price.

As you consider investing in a rehab property, it’s best to start by determining the price at which you hope to resell it. By starting with the end goal in mind, you’ll be able to look at comps and ensure the area and market can easily demand that price.

Step 2: Calculate the rehab costs.

This step requires the most work in calculating, however an estimated rehab cost will help you determine if there’s enough wiggle room in your math to even make investigating the property worth your time. If you’re unable to access the property or want to use quicker numbers, a good rule of thumb is $50/sq foot in repair costs.

Step 3: Determine the buying price.

If the property is in foreclosure or has an upcoming auction, the buying price may be an unknown. However, you should know for certain what purchase price makes you comfortable. Anything below that price is even better. And if a property is listed for sale, you should similarly know the purchase price you want as it relates to what you’d negotiate for and what you’d walk away from. A good rule of thumb for an expected purchase price is 70% of your projected sales price, less repairs.

Before You Borrow, Make Sure The Deal Makes Sense

 Doing some simple math that assumes you use all cash for this investment will swiftly show whether or not it’s worth proceeding further.

Target Sales Price

– (Rehab Costs + Purchase Price + Closing Costs + Holding Costs)


This calculation is based on an unlevered investment model and therefore has no financing costs involved. Now, if the profit is significant enough, you’ll want to take a closer look at the property and determine the actual profit and return while levering a hard money loan.

Calculating ROI On A Fix & Flip Via A Hard Money Loan

Let’s say you found an investment property you wanted to fix & flip and negotiated a purchase price of $80,000. You planned to spend $20,000 in rehab expenses and created a rehab timeline of 90 days. Let’s compare the calculations of borrowing versus doing a cash deal.

Hard Money Loan Cash Deal
Purchase Price 80,000 80,000
Rehab Cost 20,000 20,000
Holding Costs 4,000 4,000
Finance Costs 8,000
Total Project Cost 112,000 104,000
Loan Amount 90,000
Cash Needed 22,000 104,000
Sales Price 140,000 140,000
Closing Costs 11,200 11,200
Net Proceeds 128,800 128,800
Profit 16,800 24,800
Cash-on-cash Return 76% 24%

The above scenario illustrates the power of leverage. Funding the deal with cash, the borrower generates a net profit of $24,800 while using $104,000 of cash. This gives them an ROI of 24 percent.

Using leverage via a hard money loan, the borrower is able to generate a net profit of $16,800 on a $22,000 investment, which equates to a higher ROI of 76 percent.

When To Borrow & When To Pay Cash

Some investors utilize cash only on their investment properties and have shied away from borrowing. However, as illustrated above, investors can generate higher cash-on-cash returns by partnering with a hard money lender in order to help leverage their cash.

For example, an investor with $120,000 in cash might be able to purchase one property at a time, rehab it over the course of 3 months and resell it. This process may be repeated 3-4 times during the year.

Partnering with the best hard money lender would allow that same investor to leverage his or her cash by investing $30,000 per property for up to 4 properties at once, while borrowing the rest.

Additionally a hard money lender offers many benefits in addition to financing. They add to your real estate investment team to help you:

  • Evaluate each investment property’s ROI
  • Provide due diligence on contractors and suppliers
  • Guide you through the entire investment and rehab process from initial due diligence to completion of the deal through sale or refinance

I appreciate your team's support during the entire rehab process for my property. This is my first deal, there were a lot of unknowns that came with that. The construction process intimidated me and held me back from doing real estate for several years. Kurt has been phenomenal, he was a wealth of knowledge. I appreciate how he gets in touch to talk through in-scope item completion and aligning on ways to ensure my construction draws are adequate. I'm thankful to have someone who has my business's best interests at heart.
