Higher interest rates have made rental property investing more challenging in Tucson, particularly for buyers who rely on financing.
The same rates can have almost the opposite effect on existing owners. If you already have a rental property financed at 3% or 4%, that mortgage may be increasingly difficult to replace—and potentially an important reason to think carefully before selling.
For rental property owners, the real question isn't whether today's interest rates are good or bad. It's whether the property, financing, and investment still work together.
Quick Answer: How Do Higher Interest Rates Affect Rental Property Owners?
Higher interest rates increase the cost of buying rental property and make positive cash flow harder to achieve. They can also reduce investor competition and make existing low-rate mortgages considerably more valuable.
For current owners, a favorable mortgage can strengthen the case for holding a rental—but only if the property itself still has solid economics.
A good mortgage and a good investment are not the same thing.
Why Higher Rates Make Rental Property Purchases More Difficult
The effect of higher interest rates becomes obvious when you look at the monthly payment.
Consider a $300,000, 30-year mortgage.
At 4%, the principal-and-interest payment is approximately $1,432 per month.
At 7.03%, it's approximately $2,002 per month.
That's roughly $570 more every month for exactly the same amount of borrowed money.
And that's before property taxes, insurance, vacancy, repairs, capital improvements, HOA expenses, or property management.
Freddie Mac reported an average 30-year fixed mortgage rate of 7.03% as of September 24, 2026. Investment-property rates can differ from conventional owner-occupied mortgage rates, but the example illustrates why today's financing environment has changed the investment calculation.
In our experience, investors become less active when financing costs increase. The deals that worked easily with inexpensive financing become harder to find.
That doesn't mean there aren't good rental property investments. It means investors have to be more selective about what they buy and what they pay.
Tucson's Lower Property Prices Don't Eliminate the Financing Challenge
Tucson has a different price-and-rent relationship than Phoenix, which is one reason we don't think investors should evaluate the two markets exactly the same way.
As of August 2026, Zillow reported a typical Tucson home value of approximately $321,900 and average rent of approximately $1,425.
Those citywide figures aren't a substitute for evaluating an individual rental. A three-bedroom home near a major employment area can have very different economics from an older property requiring significant repairs or a home competing with a large supply of nearby rentals.
But the numbers provide useful context.
Lower acquisition costs can make the market accessible at a lower total investment than more expensive markets. At the same time, higher borrowing costs still consume a meaningful portion of the rent a property generates.
The result is that purchase price matters more than ever.
Investors can't assume that a property will work simply because homes are less expensive than in some other Southwest markets.
Look at the Entire Return, Not Just Monthly Cash Flow
Cash flow is important. But focusing exclusively on the amount left over each month can give an incomplete picture of a rental property's economics.
Rental property returns can potentially come from four places:
- Cash flow: Rental income remaining after operating expenses and financing costs.
- Mortgage paydown: Principal payments gradually reduce the debt and increase owner equity.
- Appreciation: The property may increase in value over a long holding period, although appreciation is never guaranteed.
- Tax benefits: Rental real estate may provide depreciation and other tax benefits depending on the investor's circumstances.
Residential rental buildings are generally depreciated over 27.5 years under the IRS General Depreciation System. Individual tax circumstances vary, so investors should discuss tax strategy with a qualified tax professional.
We've seen properties where monthly cash flow alone doesn't tell the entire story. Principal reduction, potential appreciation, and depreciation benefits can materially affect the overall return.
But those benefits shouldn't be used to make a bad deal look good.
A property should have reasonable underlying economics before an investor starts counting on appreciation or tax benefits.
Existing Owners May Have Something Buyers Can't Easily Replicate
For an owner who bought or refinanced several years ago, the financing attached to the property may now be one of its most attractive characteristics.
Suppose you own a rental with a fixed mortgage at 3.5%.
If you sell it and purchase another investment property, you may be exchanging that inexpensive financing for a substantially higher borrowing cost.
Selling therefore isn't just a decision about the property.
You're also deciding whether to give up the financing attached to it.
Economists describe part of this phenomenon as the mortgage lock-in effect. Federal Reserve research has found that the gap between existing homeowners' mortgage rates and prevailing market rates significantly reduced homeowner mobility after interest rates increased.
We see the same basic consideration with rental property owners. When an owner has favorable long-term financing, that mortgage deserves to be included in the hold-or-sell decision.
Don't Confuse a Great Mortgage With a Great Rental
This distinction is particularly important.
A good mortgage and a good investment are not the same thing.
We generally encourage owners to think carefully before giving up favorable long-term financing. But we don't recommend keeping an unfavorable rental solely because the mortgage rate is attractive.
Consider the property itself:
- Is the rent appropriate for the amount of equity invested?
- Is the property consistently attracting qualified residents?
- Are maintenance costs reasonable?
- Does the property have significant deferred maintenance?
- Are major capital expenses approaching?
- Are taxes, insurance, HOA expenses, and other ownership costs increasing?
- Does the property still fit your investment objectives?
This can be particularly important with Tucson's older housing stock.
An inexpensive mortgage doesn't offset an investment that requires significant ongoing repairs, has weak rental economics, or no longer fits the owner's financial goals.
Conversely, a property purchased with a higher interest rate can still make sense if the price and overall economics are attractive.
The mortgage should be part of the investment decision—not the entire investment decision.
Higher Rates Are One Reason Homeowners Become Accidental Landlords
Not every landlord originally intended to own rental property.
Some become landlords after moving for work, military service, family reasons, or a change in housing needs. Others purchase another home but decide not to sell their previous residence.
Today's interest-rate environment adds another consideration.
A homeowner who has a 3% or 4% mortgage may hesitate to give it up—especially when replacing that home or purchasing another investment could require substantially more expensive financing.
Renting the property instead of selling can preserve the existing mortgage while allowing the owner to retain the home as a long-term investment.
But the favorable loan shouldn't make the decision automatically.
Before converting a home into a rental, the owner should evaluate realistic market rent, vacancy, management, maintenance, property condition, future capital expenses, insurance, taxes, and the amount of equity tied up in the home.
Our Tucson Accidental Landlord's Guide goes deeper into that decision and the practical issues involved in converting a former residence into a rental.
Higher Rates Can Create Opportunities for Investors, Too
The current environment isn't entirely negative for buyers.
When financing is inexpensive and investment properties are easy to cash flow, more investors tend to compete for them.
Higher borrowing costs can reduce that competition.
That leads to an investment principle we think is particularly important:
There is a big difference between paying a high interest rate and paying too high a price for a property.
If an investor purchases a good property at an attractive price with expensive financing, there may eventually be an opportunity to refinance if rates decline.
If an investor pays too much for the property, there is no equivalent solution.
You can potentially refinance an expensive loan. You can't refinance away an excessive purchase price.
That doesn't mean investors should assume rates will decline.
A property purchased today should make sense based on today's reasonable economics. Refinancing should be viewed as possible future upside—not something required to make the investment work.
What Higher Rates Can Mean for Tucson Rental Demand
Interest rates don't affect landlords only through their mortgage payments.
They also influence the rent-versus-buy decision.
As mortgage rates increase, so does the monthly payment required to purchase the same home. Some households that might otherwise buy therefore remain renters longer.
That can support rental demand.
Tucson also has its own demand drivers. The University of Arizona, Davis-Monthan Air Force Base, major employers, population changes, seasonal patterns, and the supply of available housing can all influence rental activity.
Those factors don't affect every neighborhood or property equally.
A home that works well for a long-term resident near an employment center may behave differently from a property heavily influenced by university demand or another localized source of renters.
That's another reason we prefer evaluating rental properties individually rather than relying on broad statements about the market.
Higher interest rates can support rental demand, but they don't guarantee higher rents.
Inflation Can Favor Owners With Long-Term Fixed Debt
Inflation can create another advantage for some long-term rental property owners.
Over time, inflation can contribute to higher rents and asset values. But the principal balance on a conventional fixed-rate mortgage doesn't increase simply because the value of money changes.
An owner may therefore be collecting future rents in higher nominal dollars while continuing to repay debt established years earlier.
In effect, inflation can reduce the real burden of fixed-rate debt over time.
This is one reason long-term fixed-rate financing can be particularly valuable.
But the same principle applies here as elsewhere in the investment: favorable financing can't turn an unfavorable property into a good one.
What We Recommend to Rental Property Owners
If you already own a rental with attractive long-term financing, don't give up that mortgage casually.
Start with the property.
Determine its realistic market rent. Calculate actual operating expenses. Consider vacancy, maintenance, management, insurance, taxes, HOA expenses, and upcoming capital improvements.
Then look at the equity you have invested and the return the property is generating on that equity.
Finally, consider the financing.
A low-rate mortgage can make an already good rental property significantly more attractive to hold.
But our approach is straightforward:
Keep favorable financing when the underlying property also makes sense to own. Don't keep an unfavorable property simply to keep a favorable mortgage.
Should You Keep or Sell a Tucson Rental With a Low Mortgage Rate?
There isn't one answer for every owner. These questions can help frame the decision.
What would the property realistically rent for today?
Don't base the decision on what the property rented for several years ago or what you hope it might rent for. Start with current market conditions and comparable rentals.
What does the property actually cost to own?
Include more than the mortgage. Account for maintenance, vacancy, management, taxes, insurance, HOA expenses, and long-term capital expenditures.
How valuable is the existing mortgage?
The lower the rate relative to financing available today, the more valuable that financing may be.
How much equity is tied up in the property?
Positive cash flow alone doesn't necessarily mean an investment is performing well. An owner with substantial equity should also consider the return being generated on that equity.
What condition is the property in?
This can be particularly important with older properties. A low mortgage payment may look attractive until significant roofing, HVAC, plumbing, electrical, or other capital expenses are considered.
Would you buy this property today?
This is one of our favorite ways to think about an existing rental.
Ignore what you originally paid for a moment. If you had the property's current equity available in cash today, would you choose to invest it in this property?
The answer can help separate attachment to an existing investment from its current economics.
Frequently Asked Questions
Does a low mortgage rate mean I should keep my rental?
No. A low mortgage rate is valuable, but the property should also have reasonable rental economics and fit your investment objectives. Evaluate cash flow, equity, condition, future expenses, and long-term prospects along with the financing.
Are rental properties still worth buying when interest rates are high?
Some can be. Higher financing costs make attractive investments harder to find, so purchase price and property selection become particularly important. Evaluate a property using current financing rather than assuming rates will decline later.
Are Tucson's lower home prices better for rental property investors?
Lower acquisition costs can reduce the total capital required to purchase an investment, but price alone doesn't determine whether a property is attractive. Investors should evaluate the relationship among purchase price, achievable rent, operating expenses, financing, property condition, and long-term prospects.
Can higher mortgage rates help landlords?
Higher rates can make homeownership more expensive and cause some households to remain renters longer, potentially supporting rental demand. For existing landlords, higher market rates can also make an older low-rate mortgage more valuable. Neither effect guarantees that an individual rental will perform well.
Should I rent my Tucson home instead of selling it because I have a low mortgage rate?
A low mortgage rate is a good reason to evaluate the rental option, but not necessarily a reason to become a landlord. Estimate realistic rent and all ownership expenses and consider the property's condition, equity, management needs, and long-term investment potential. Our Tucson Accidental Landlord's Guide provides a more detailed framework for that decision.
Interest Rates Matter, But the Property Still Comes First
Higher rates have made it harder for investors to find properties that produce attractive returns with conventional financing.
At the same time, they have made the low-rate mortgages held by many existing property owners more valuable.
Both matter.
But neither should replace a careful evaluation of the actual property.
The strongest rental investments combine a reasonable purchase price, sustainable expenses, appropriate financing, rental demand, manageable property condition, and long-term potential.
The goal isn't simply to own a low-rate mortgage. It's to own a property that makes sense as an investment.
