Are You Evaluating Properties Wrong?

The 1% rule was the benchmark: If a property rented for roughly 1% of its purchase price each month, it was generally considered a good candidate for cash flow.

Unfortunately, higher interest rates, property taxes, insurance costs, and operating expenses have changed that.

Today, I believe we need a better way to evaluate cash-flow potential. That’s why I created a metric I call the Rent-to-Payment Ratio.

The formula is simple:

Monthly Rent ÷ Monthly PITI Payment = Rent-to-Payment Ratio

PITI stands for principal, interest, taxes, and insurance.

Instead of comparing rent to the purchase price, I compare rent to the property’s actual monthly mortgage payment. This gives me a much better picture of how rising interest rates, property taxes, and insurance costs affect cash flow.

The New Benchmark for Cash Flow

After ranking major U.S. metros by their rent-to-payment ratios, I believe we can establish some useful benchmarks for investors in 2026.

A ratio of 1.0 is still the gold standard. At 1.0, the monthly rent equals the property’s principal, interest, taxes, and insurance payment.

But 1.0 is no longer a magical threshold.

Based on my analysis, I consider a ratio of 0.75 or higher to be a market where cash-flow opportunities can still exist. Below 0.75, finding cash flow becomes significantly more difficult—but it isn’t necessarily impossible.

These numbers are designed to identify deals with greater cash-flow potential, not to replace a proper property-level analysis.

For example, if a metro has an average rent-to-payment ratio of 0.60, that doesn’t mean every property in the market has a 0.60 ratio. By definition, roughly half of the properties will perform above the average.

My goal is to use these rankings to identify deals where the odds of finding a good cash-flowing deal are higher.

Once I identify a deal, it is my job to find properties that outperform the market average.

And, of course, I still need to run a complete deal analysis before buying anything. Rules of thumb are useful for narrowing down opportunities, but they should never replace detailed underwriting.

The New Reality: Cash Flow Has to Be Found

Across the 54 metros I analyzed, the average rent-to-payment ratio is approximately 0.80, with a median of about 0.76.

That means that in a typical major-city investment, market rent covers only about 76% to 80% of the property’s total monthly PITI payment.

That is a dramatic change from the days when a 1% rent-to-price ratio was considered relatively easy to find.

Today, I look at the market this way:

• 1.00+ — Excellent cash-flow potential
• 0.75–0.99 — Workable, but requires careful deal selection
• Below 0.75 — Difficult cash flow environment

.

When the ratio falls below 0.75, I generally need something else to make the deal work. That could mean buying significantly below market value, achieving above-market rents, adding bedrooms or other value-add improvements, or using a different investment strategy altogether.

For experienced investors, the question is no longer simply, “Where can I buy a property that cash flows?”

Instead, I want to know:

Which deals are close enough to break-even that my ability to source, negotiate, underwrite, and add value can turn an average deal into a good one?

That’s a much more useful way to think about today’s market.

Where the Cash Flow Is: Midwest and Northeast Markets

One of the clearest patterns in the data is that many of the strongest cash-flow markets are areas where home prices remain relatively affordable while rents have remained strong.

At the top of the rankings is Detroit, with a rent-to-payment ratio of approximately 1.99.

That means average market rent is nearly twice the modeled monthly PITI payment.

Detroit has an average home value of roughly $72,000 and average rent of approximately $1,280 per month. With relatively modest principal and interest payments, combined with comparatively manageable taxes and insurance, the spread between rent and PITI can provide a substantial cushion.

That cushion matters.

It gives investors more room to absorb vacancies, capital expenditures, maintenance, and future increases in taxes or insurance.

Other Midwest markets—including Cleveland, St. Louis, Cincinnati, Indianapolis, Columbus, Chicago, and Kansas City—also fall within a generally workable range, with ratios typically between 0.81 and 1.19.

In these markets, the challenge shifts away from simply finding a market that can cash flow. Instead, success depends heavily on the property, neighborhood, rental income, tenant quality, and acquisition price.

What the Numbers Don’t Tell You

There is one major limitation to any market-level analysis:

The numbers don’t tell me what I’m actually buying.

For example, knowing that Detroit has homes available for under $80,000 tells me very little about the quality of those homes or the neighborhoods where they are located.

Paper cash flow is one thing. Real-world cash flow is something else entirely.

Crime, neighborhood conditions, tenant quality, property condition, deferred maintenance, and socioeconomic factors can quickly destroy what initially appears to be a great deal.

That’s why I believe market-level data should be the beginning of the process—not the end.

I need good local data, experienced professionals, and reliable agents and brokers who understand the individual neighborhoods.

Cash flow on paper doesn’t always translate into cash flow in the real world.

Always do your due diligence.

When Cash Flow Is Almost Impossible

At the opposite end of the rankings are markets where high home prices overwhelm otherwise strong rents.

San Jose, San Francisco, Los Angeles, Seattle, and San Diego all have strong rental markets, but their home prices push monthly PITI payments far beyond what rents can reasonably support.

For example:

• San Jose: approximately 0.39
• Austin: approximately 0.40
• Los Angeles: approximately 0.49
• Seattle: approximately 0.49
• San Francisco: approximately 0.52
• San Diego: approximately 0.56

.

Austin is particularly interesting because it was one of the major pandemic-era growth markets. Although home prices have come down from their peaks and rents have softened, the market still has a relatively low rent-to-payment ratio.

In these markets, I generally wouldn’t buy a property solely for leveraged cash flow.

Investors may instead be looking for long-term appreciation, a place to park capital, or a specialized value-add opportunity.

Buying all cash can also dramatically change the economics.

Another possibility is finding a property where I can add significant value—such as adding bedrooms, an ADU, or other income-producing improvements—to increase rents enough to move the property toward break-even.

Taxes and Insurance Can Change Everything

One of the biggest lessons from this analysis is that purchase price isn’t the only thing that matters.

Taxes and insurance have increased dramatically in many markets, and those expenses can turn what once looked like a good investment into a marginal or negative-cash-flow property.

Oklahoma City is a good example.

The market has a rent-to-payment ratio of approximately 0.56, and one major reason is the cost of homeowners insurance. Insurance alone represents roughly 40% of the modeled PITI payment.

That’s significant.

In markets such as Houston and Miami, exposure to hurricanes, flooding, wind, hail, and other severe weather has pushed insurance costs substantially higher.

Houston and Miami have average annual insurance costs of approximately $7,860 and $6,000, respectively.

Those costs directly reduce the amount of rent available to cover debt service and other expenses.

By comparison, markets such as Birmingham and Indianapolis benefit from relatively low effective property-tax rates and more moderate insurance costs. That leaves more room for rental income to cover the property’s monthly expenses.

This is why I believe sophisticated investors need to look beyond purchase price and rent.

I want to understand what makes up the payment.

Two properties with the same purchase price and rent can have completely different cash-flow profiles if one has dramatically higher taxes and insurance.

Why Payment Matters More Than Price

In 2026, I don’t believe rent-to-price ratios are enough to properly evaluate a rental property.

My rent-to-payment analysis assumes a 6.5% interest rate, a 30-year fixed mortgage, and 20% down, while incorporating city-level property taxes and insurance.

That provides a much more realistic picture of what an investor’s monthly financial obligation actually looks like.

The difference becomes particularly important when taxes and insurance vary significantly from one market to another.

For me, market selection isn’t simply about finding the lowest-priced homes or the highest rents.

I want to find markets where price, rent, taxes, and insurance are in balance.

Ideally, I want taxes and insurance to remain reasonable relative to property values so that future rent growth can translate into additional cash flow.

I also want to be cautious about markets where insurance or other non-mortgage expenses are being driven higher by climate or regulatory risks.

In those markets, getting a great purchase price may not be enough to save the deal.

The Regional Divide: Why the Midwest Wins

The regional differences in the data are significant.

The Midwest is the only major region with an average rent-to-payment ratio above 1.0, at approximately 1.01.

The other regions are considerably lower:

• Midwest: 1.01
• Northeast: 0.89
• South: 0.78
• West: 0.61

.

That tells me that, on average, the Midwest currently offers the strongest environment for leveraged cash flow.

The West is particularly challenging. At an average ratio of 0.61, the typical property is already significantly underwater on PITI before I even account for maintenance, vacancy, capital expenditures, and other operating expenses.

Midwest

I would still drill down into specific neighborhoods, streets, property types, and strategies. A strong market average doesn’t automatically make every property a good investment.

Northeast

Markets such as New York, Boston, and Philadelphia offer strong tenant demand and limited housing supply. The trade-off is generally lower cash-flow potential, with investors often accepting lower yields in exchange for stability and potential appreciation.

South

The South is much more uneven.

Blue-collar markets such as Memphis and Birmingham can offer strong cash-flow opportunities, while higher-priced growth markets such as Austin, Atlanta, Nashville, Tampa, and Houston can be much more difficult to cash flow using traditional financing.

West

For me, Western markets are primarily appreciation and wealth-preservation plays rather than leveraged cash-flow markets.

Cash flow with debt is extremely difficult to achieve in the typical property.

How I Would Use These Rankings

If I were building or expanding a rental portfolio in 2026, I would use this data as a market-screening tool—not a buying list.

My strategy would be straightforward.

1. Start with high-ratio markets

Markets such as Detroit, Cleveland, Memphis, Birmingham, Hartford, and St. Louis deserve a closer look if my primary objective is cash flow.

2. Investigate the middle

Markets with ratios between approximately 0.75 and 1.0 can still offer opportunities.

These markets may provide a combination of modest cash flow and appreciation, but I would need to be more selective about acquisition price and property quality.

3. Treat low-ratio markets as specialty plays

Markets such as Austin and many West Coast cities require a different strategy.

Cash purchases, short-term rentals, significant value-add projects, or long-term appreciation may make sense, but I wouldn’t expect the average leveraged rental property to produce strong cash flow.

Final Thoughts

The good news is that cash flow hasn’t disappeared.

Even with interest rates around 6.5%, high home prices, and rising property taxes and insurance costs, there are still large parts of the country where rental properties can cash flow—or at least get close to breaking even.

The key is that I can no longer rely on the old rules of thumb.

The 1% rule and rent-to-price ratios can still provide a quick starting point, but they don’t tell me what the property is actually going to cost me every month.

That’s why I created the Rent-to-Payment Ratio.

It gives me a simple way to compare rental income against the property’s actual PITI obligation and identify markets where cash flow has a better chance of working.

But this is only the first step.

Once I identify a promising market, I still need to find the right property, negotiate the right price, accurately estimate repairs and expenses, understand the neighborhood, and run a complete investment analysis.

The numbers can point me in the right direction.

It’s still my job to find the deal.
