Owning rental property has created more everyday millionaires than almost any other strategy. Unlike flipping houses, where you're constantly hunting for the next deal, buy-and-hold investing builds wealth steadily over decades. You collect rent every month, your tenants pay down your mortgage, and the property appreciates in value—all while you potentially pay less in taxes than a W-2 employee earning the same income.
But rental property investing isn't for everyone, and it's not entirely passive. There are tenants to manage, maintenance to handle, and real money at risk. This guide covers what you need to know before buying your first rental—from analyzing deals to understanding the financial realities of being a landlord.
How Rental Properties Build Wealth
Rental real estate generates returns through multiple channels simultaneously, which is what makes it so powerful for wealth building.
Cash flow is the money left over each month after collecting rent and paying all expenses: mortgage, property taxes, insurance, maintenance, vacancy reserves, and property management if you use one. A well-selected property might produce $200 to $500 per month in positive cash flow—money you can spend, reinvest, or save. Over time, as rents increase and your mortgage balance decreases, cash flow typically grows.
Appreciation builds wealth even when you're not looking. Historically, U.S. home values have appreciated 3-5% annually on average, though this varies significantly by market and time period. A property that costs $200,000 today might be worth $250,000 or more in five to seven years. You benefit from appreciation on the entire property value, not just your down payment.
Mortgage paydown happens every month as your tenants' rent covers your loan payment. Each payment reduces your principal balance and increases your equity. Over 30 years, your tenants essentially buy the property for you. After the mortgage is paid off, nearly all the rent becomes cash flow.
Tax advantages set real estate apart from other investments. Depreciation allows you to deduct a portion of the property's value each year (typically over 27.5 years), even though the property may actually be appreciating. This paper loss often eliminates your tax bill on rental income entirely. You can also deduct mortgage interest, property taxes, insurance, repairs, and virtually every expense related to the property.
When you sell, you can defer capital gains taxes indefinitely through a 1031 exchange, rolling profits into a larger property. Some investors never pay capital gains taxes, exchanging up throughout their careers and passing properties to heirs at a stepped-up basis.
Analyzing Rental Properties
The difference between a good investment and a money-losing mistake comes down to the numbers. Before making an offer on any property, you need to project cash flow and returns with realistic—even conservative—assumptions.
The 1% rule is a quick screening tool: monthly rent should equal at least 1% of the purchase price. A $200,000 property should rent for at least $2,000 per month to have a reasonable chance at positive cash flow. Properties that don't meet this threshold aren't automatically bad, but they need closer scrutiny.
Cash-on-cash return measures how hard your actual investment is working. It's your annual cash flow divided by the total cash you invested (down payment, closing costs, initial repairs). A rental producing $4,800 per year in cash flow on a $40,000 investment generates a 12% cash-on-cash return—significantly better than most stock market returns, and that's before counting appreciation or loan paydown.
To calculate cash flow, start with gross rental income, then subtract everything: mortgage payment (principal and interest), property taxes, insurance, HOA fees if applicable, maintenance (budget 5-10% of rent), vacancy (5-10% of rent), and property management if you won't self-manage (8-10% of collected rent). What's left is your cash flow. Be conservative—expenses almost always end up higher than expected.

Financing Investment Properties
Financing rentals is different from financing a home you'll live in. Lenders see investment properties as higher risk—you're more likely to walk away from a rental than from your primary residence if things go wrong—and they price accordingly.
Expect to put 15-25% down, with 20-25% being most common. Some portfolio lenders and credit unions offer lower down payment options, but they're the exception. The more you put down, the better your cash flow (since your mortgage payment is lower) and often the better your interest rate.
Interest rates on investment properties run 0.5% to 1% higher than owner-occupied rates. That half-point difference adds up—on a $200,000 loan, it's about $60 per month.
Lenders want to see cash reserves—typically six months of mortgage payments per property—to ensure you can cover vacancies or unexpected repairs. They'll also scrutinize your debt-to-income ratio, though many lenders allow you to count a portion of projected rental income (usually 75%) to help qualify.
A credit score of 680 or higher is generally needed for investment property loans; 720+ gets you the best rates. If you're below these thresholds, consider improving your credit before investing or looking into alternative financing like portfolio lenders or private money.
Property Management: DIY or Hire Out?
You can manage rental properties yourself or hire a property manager. Each approach has trade-offs.
Self-management maximizes cash flow since you're not paying the 8-10% management fee. You control tenant selection, maintenance decisions, and how quickly issues get resolved. But you're also on call for emergencies, responsible for showing units, collecting rent, handling repairs (or coordinating contractors), and dealing with problem tenants. For local properties and investors with time and temperament for landlording, self-management often makes sense, at least initially.
Property managers handle the day-to-day: tenant screening, rent collection, maintenance coordination, and legal compliance. Good managers earn their fee through lower vacancy rates, better tenant selection, and efficient maintenance. They're essential for out-of-state investing or investors who don't want landlording to be a second job. The cost typically runs 8-10% of collected rent, plus fees for tenant placement (often one month's rent) and sometimes markups on maintenance.
Many investors start self-managing to learn the business, then transition to property management as their portfolio grows or their time becomes more valuable.
Getting Started
Your first rental doesn't need to be perfect—it needs to be a solid deal that teaches you the business. Many successful investors start with a house hack: buying a duplex, triplex, or fourplex, living in one unit, and renting the others. This lets you use owner-occupied financing (lower down payment, better rates) while learning to be a landlord with training wheels.
Focus on properties in neighborhoods you understand, with numbers that work even under conservative assumptions. Build relationships with a real estate agent who works with investors, a lender who does investment loans, and contractors you can call when things break.
Most importantly, run the numbers on everything. The more deals you analyze, the better you'll recognize good opportunities when they appear. When you find a property that cash flows with realistic projections and fits your investment criteria, you'll be ready to act.
Start building your team before you need them: a lender who understands investment properties, a real estate agent who works with investors, a handyman or general contractor for repairs, and perhaps a property manager for the future. When a great deal appears, you'll be ready to move fast.
