Rental Income

What it is

Rental income is the monthly rent a tenant pays you to live in a property you own. It’s one of the wealth engines on every rental — alongside appreciation, equity paydown, and tax advantages.

Here’s the honest picture of what it looks like when you actually receive it. You get $1,500 bucks a month to live there. Well, think of it like when you go buy a bag of Doritos. You get a big old bag, you’re pumped about it, then you open it up, and you only get like a third of it full of chips. That’s what happens when you get your rent money. You got to pay property management. You got to pay for maintenance. You got to put money aside for CapEx. You got to pay your taxes, property taxes. You got to pay insurance. You got to put money aside for vacancy because people don’t live there indefinitely. They move out, you fix it up a little bit, put it back on the market. You don’t get the whole bag of chips. You only get some of them. That is your net operating income.

Why it matters

Flips are the groceries — chunks of cash every three to six months. Rentals are the retirement plan. Both are needed.

The mistake most new investors make is judging a rental by cash flow alone. When the net NOI looks like $42/month, they reject it. But that same property is appreciating, the tenant is paying down your mortgage, and you’re writing off depreciation against other income. Stack all four engines and the return on your down payment approaches a number you’d never get from a check.

Here’s where it really hits you. I went on an appointment once to buy a house from this guy. I looked him up before I went. He owned 50 houses. No mortgages. All 50 outright in cash. I show up and it’s this dude in an HVAC van — Bubba Hicks. I’m like, there’s no way this is the guy. We go on the appointment, and afterward I ask him straight up: how do you own 50 houses in cash? He says, “About 30 or 40 years ago, my neighbor wanted to sell a house. They said $100,000 for it. I went to the bank and said, will you give me $100,000 to buy this house? And they did. I put a renter in it. I used the money that the renter gave me and paid the mortgage. Then another neighbor wanted to sell. I went back to the bank, got the money, put a tenant in that one. Paid the mortgage with that rent. Did that 48 more times. After 30 years, all the mortgages were gone.”

That’s it. That’s the whole thing. Grab assets, put tenants in them to pay for it. The rent covers the debt, the debt burns down month after month, and one day you own 50 houses in cash.

How it shows up

The 1 percent rule exists for this reason. If monthly rent isn’t close to 1% of purchase price, the math rarely survives the operating costs bite plus the mortgage. That’s the quick filter before you dig into the actual numbers.

The 31 percent rule is the operating cost side: 7% vacancy, 8% maintenance, 8% CapEx, 8% property management — that’s 31% of gross rent gone before the mortgage. On $1,800 rent, that’s roughly $558 in operating costs. Whatever’s left after that has to cover the debt service and leave you something. Dreamers look at gross. Operators look at what’s actually left.
