How to Calculate ROI on Property Investment - Miami Real Estate

As an investor, you should know the value of your property investment and the returns you get from it. This should tell you if the investment is profitable or not. If profitable, to what percentage? Is it too little or just okay?

Return On Investment (ROI) is the simplest way to evaluate whether your investment was profitable, broke even, or unprofitable.


Before you take any step further, feel free to check out this rent calculator built to help property investors and landlords for estimating their return on investments.

What is ROI in Property Investment?

Return on Investment (ROI) is the ratio of income to Investment cost. This ratio can either be positive or negative. If positive then your investment was profitable, if negative, you should reevaluate that investment.

In property investment, ROI is used to show how profitable the property is from annual records. Let's look at how you can calculate ROI on your own.

How to Calculate ROI for Your Property Investment:

To get the Return on Investment, first, you have to calculate the gross profit or gross loss. That is;

Total income - Expenses = Gross Profit

Then you find the ratio of that to the Investment cost.

Net profit ÷ Investment cost = ROI Ratio

Take the ratio and multiply by 100 to get the percentage. Let's look at how you can calculate this if you had a property.

Calculating ROI on Different Real Estate Investments

There are several ways you can invest in the real estate industry. You don't have to own a building. Amazing, right?

Here are some of the popular ways to invest in real estate:

  1. Flipping houses

  2. REITs

  3. Rental

ROI on Flipping Houses

Zack bought a house for $100,000. He repaired the house at $20,000 then resold it for $150,000.

The total cost incurred on the investment is $100,000 + $20,000 = $120,000

Net profit:

$150,000 - $120,000 = $30,000


($30,000 ÷ $150,000) × 100 = 20%

What if Zack bought and sold in the wrong season in Miami? He buys a house during summer and sells it during winter. The Purchase price is still $100,000 and repairs sum up to $20,000.

If he sold the house at $110,000 because he couldn't find a better deal, what would the ROI be?

Total cost incurred:

$100,000 + $20,000 = $120,000

Net profit:

$110,000 - $120,000 = -$10,000

Return on Investment:

(-$10,000 ÷ $120,000) × 100 =


If only he could have been a little more patient!

ROI on Real Estate Investment Trusts (REITs)

This is the simplest way to invest in real estate. You'll notice that anyone can do this, even a 12-year-old. Yes, that 12-year-old.

What are REITs in Property Investment?

Real Estate Investment Trusts (REITs) is a simple investment style where you buy a share of the property. Just like the stock market.

This enables you to invest in real estate even if you have limited funds to own a building. That's why we say it's for everyone. How thoughtful.

If you buy shares from a REITs company, the shares will earn you dividends. Zack decided to invest in REITs this time. He deposited $50,000 into his account and invested. At the end of that financial year, he had earned $10,000.


(10,000 ÷ 50,000) × 100 = 20%

That's a juicy cheque right there!

As you have noticed there is no other cost apart from the investment cost. We also didn't subtract the income from the cost incurred. That is because the investment cost can be gained when you decide to sell your shares of the REITs.

Returns on REITs fluctuate depending on the market conditions. He could earn 30% next year and then 10% the year after that.

Calculating the Return On Investment (ROI) on Rental Property

Calculating Return on Investment for a rental property depends on how you bought the property. Was it financed or bought with cash?

There is a specific way to calculate for each of those:

  • Cost Method

  • Out-of-Pocket Method

Cost Method (for cash transaction)

Zack bought a house at $500,000 with a closing cost of $4,000. Repairs cost him $16,000. Paid all this with cash.

Monthly expenses including gas bills, taxes, and maintenance add to $1,000. He receives $5,000 in rent monthly from the property.

Net Profit:


$5,000 × 12 months = $60,000


$1,000 × 12 months = $12,000

Income - Expense = profit

$60,000 - $12,000 = $48,000

Purchase cost:

$500,000 + $4,000 + $16,000 = $520,000


(48,000 ÷ 520,000) × 100 = 9.2%

Out-of-pocket method (for financed transactions)

If he bought the same house using a mortgage, what would be his ROI?

To get a $500,000 mortgage loan, he had to make a 10% down payment. The closing cost was $4,000 while repairs cost $16,000.

The mortgage is for 30 years with an interest rate of 6% for the $450,000 lent. That means he would have to pay monthly installments of $2,698. Monthly expenses add up to $1,000 while monthly rent is $5,000.


$5,000 × 12 = 60,000


$2,698 × 12 = 32,364

$1,000 × 12 = 12,000

$12,000 + 32,364 = 44,364

Net profit:

$60,000 - 44,364 = $15,636

Cost incurred in the investment:

Down-payment + Closing cost + Repair cost

$50,000 + $4,000 + $16,000 = $70,000


(15,636 ÷ 70,000) × 100 = 22.34%

Amazing numbers, right?
