A few days ago, someone asked me: “Is this property a good investment?”

The property looked nice. Good location. Decent rent. The seller was also saying, “This is a great opportunity.”

But in real estate, “looks good” is not enough. Because a property can look like a dream… and still behave like an expensive headache. 😅

So I asked one simple question:

What do the numbers say?

Let’s take a simple real-life example

Suppose you are planning to buy a rental property for $250,000.

Expected rent: $2,200/month. That means yearly rent:

$2,200 × 12 = $26,400

At first, it looks good. But now let’s add real life.

Because real estate also comes with: vacancy, property tax, insurance, repairs, maintenance, management cost, and unexpected surprises.

Let’s say total yearly expenses are around $9,000. Also, assume vacancy loss is $1,320.

So actual rental income becomes:

$26,400 − $1,320 = $25,080

Now calculate NOI

NOI = Rental Income − Operating Expenses

$25,080 − $9,000 = $16,080

So the property makes $16,080/year before loan payments.

Now check the cap rate

Cap Rate = NOI ÷ Property Price

$16,080 ÷ $250,000 = 6.43%

Not bad. But here comes the important part.

Now check the real cash flow

Suppose your yearly loan payment is $15,600. Now your actual cash flow is:

$16,080 − $15,600 = $480/year

That is only $40/month.

So technically, the property is profitable. But practically?

One small repair can wipe out the whole year’s profit. One broken water heater and your investment starts behaving like a needy best friend. 😄

This is why I believe investors should not only ask: “Will this property appreciate?” They should also ask:

“Can this property survive bad months?”

Before investing, check these numbers

1. Cash Flow — How much money is left after all expenses?

2. Cap Rate — How much return does the property generate compared to its price?

3. Vacancy Risk — What happens if the property is empty for a month?

4. Repair Buffer — Do you have cash ready for unexpected costs?

5. Cash-on-Cash Return — How much return are you getting on the money you actually invested?

My takeaway

Real estate investing is not about falling in love with the property. It is about falling in love with the numbers.

Because good numbers give you confidence. Bad numbers give you stress, late-night calculations, and random Google searches like: “How much does plumbing repair cost?” 😅

Before buying any property, don’t just check the location. Check the math.

The deal is only good when the numbers make sense.
