The Data Behind the Buying versus Renting Advantage
According to RealtyTrac, buying a home is more affordable than renting in 76 percent of U.S. counties. This finding comes from comparing monthly house payments on a median-priced home against fair market rents set by the U.S. Department of Housing and Urban Development for three-bedroom properties. The data, originally reported by HousingWire, underscores a persistent trend that shapes how builders, developers, and buyers approach the housing market. For builders looking to position their projects effectively, understanding this homeownership vs renting data provides a foundation for strategic decisions about what to build and where.
The gap between buying and renting costs varies significantly by location. In markets where the buy-versus-rent ratio strongly favors ownership, demand for for-sale homes remains elevated. Builders operating in these counties can expect stronger absorption rates and shorter cycle times. Conversely, in counties where renting holds the advantage, builders may need to adjust their product mix or explore build-to-rent opportunities.
How the Affordability Calculation Works
The comparison relies on two primary inputs. The first is the monthly mortgage payment on a median-priced home, which factors in prevailing interest rates, loan terms, and principal. The second is the HUD fair market rent for a three-bedroom unit, which represents the 40th percentile of gross rents in a given metropolitan area. When the mortgage payment falls below the fair market rent, buying becomes the financially rational choice for households that can qualify for financing.
What the 76 Percent Figure Really Means
The headline figure of 76 percent includes a wide range of market conditions. In some of these counties, the advantage for buying is narrow, perhaps only a few dollars per month. In others, the gap is substantial, with mortgage payments running hundreds of dollars below equivalent rents. Builders should examine not just whether their target market favors buying, but how large the margin is. A wider gap creates a stronger value proposition for potential buyers and provides more room to absorb modest price increases or rate adjustments.
Key Markets Where Buying Costs Less Than Renting
The RealtyTrac analysis identified specific counties where the affordability gap is especially pronounced. Three examples illustrate the range of markets where buying dominates renting.
Bay County, Michigan (Bay City Metro Area)
In Bay County, the cost advantage for buying over renting is substantial. The Bay City metro area represents a smaller manufacturing and service economy where home prices remain moderate relative to local incomes. For builders, markets like Bay County offer opportunities to serve first-time buyers and move-up purchasers who can achieve significant monthly savings by owning rather than renting.
Fayette County, Pennsylvania (Pittsburgh Metro Area)
Fayette County sits within the broader Pittsburgh metro area, a region known for stable home prices and a diversified economy. The buying advantage here reflects both affordable entry-level home prices and rental rates that have risen faster than ownership costs. Builders targeting the Pittsburgh region should note that Fayette County and surrounding areas present favorable conditions for for-sale housing.
Tazewell County, Illinois (Peoria Metro Area)
In Tazewell County, part of the Peoria metro area, the math similarly tips in favor of homeownership. Moderate home prices combined with stable rental demand create an environment where buyers can lock in lower monthly costs through a fixed-rate mortgage. For production builders, these conditions reduce the risk of holding inventory and support consistent sales velocity.
Strategic Implications for Home Builders and Developers
The affordability gap between buying and renting carries direct implications for how builders approach land acquisition, product selection, and pricing strategy. Below are several takeaways organized by area of impact.
Product Mix Decisions
In markets where buying is cheaper than renting, builders should prioritize for-sale product over rental development. The natural demand from households seeking lower monthly costs will flow toward ownership if financing is accessible. Consider the following product types:
- Entry-level single-family homes priced below the monthly equivalent of a three-bedroom rental
- Townhomes and attached product that offer lower price points while still delivering ownership benefits
- Starter homes with efficient floor plans that keep mortgage payments competitive with local rents
Pricing Strategy
Builders should price new homes so that the monthly payment (including taxes and insurance) remains visibly below the local fair market rent for a comparable three-bedroom unit. This creates a built-in value message that resonates with cost-conscious buyers. Key pricing strategies include:
- Calculate the local HUD fair market rent for three-bedroom units
- Determine the maximum home price that keeps the monthly payment below that rent at current interest rates
- Design floor plans and spec levels that hit that price point without sacrificing quality
- Emphasize the monthly savings in marketing materials to convert renters into buyers
Land Acquisition Priorities
When evaluating new parcels, builders should include buy-versus-rent affordability data in their market analysis. Counties with a wide gap offer faster absorption and lower carrying costs. Builders can use publicly available HUD fair market rent data combined with local home price trends to rank potential markets by affordability advantage.
Balancing Rental and For-Sale Strategies
Even in markets where buying is cheaper overall, certain submarkets and buyer segments will continue to rent. Builders who can operate across both for-sale and rental product lines gain flexibility. The build-to-rent sector has grown substantially as institutional capital seeks exposure to single-family rental demand. Builders who understand both sides of the affordability equation can allocate capital where the return is strongest.
When Renting Still Wins
There are scenarios where renting remains the better option even in counties where the aggregate data favors buying. These include households with insufficient credit scores for favorable mortgage terms, buyers in markets with high property taxes or insurance costs that inflate the true cost of ownership, and households that expect to move within a few years and would lose equity to transaction costs. Builders should understand these nuances to avoid overcorrecting toward for-sale product in every market.
How Builders Can Tap Rental Demand
For builders who want exposure to rental demand without abandoning their core for-sale business, several models work well. The FHFA REO Rental Program strategies offer one example of how policy initiatives have shaped the rental landscape. Additionally, builders can pursue:
| Strategy | Description | Best For |
|---|---|---|
| Build-to-Rent Communities | Single-family homes built specifically for rental operation | Markets with strong job growth but tight for-sale affordability |
| For-Sale with Optional Lease | Offer lease-to-own or rent-with-option programs | Markets where credit constraints limit buyer qualification |
| Mixed Tenure Developments | Combine for-sale and rental product in a single community | Large master-planned communities seeking diverse buyer pools |
| Portfolio Allocation | Dedicate a percentage of starts to rental product each year | Established builders with multiple active divisions |
Financing and the Homeownership Gap
Even when the monthly math favors buying, not every renter can make the transition to ownership. Down payment requirements, debt-to-income limits, and credit history all create barriers. Builders who understand the homeownership affordability math recognize that affordability is about both the monthly payment and the upfront cost. Partnering with mortgage lenders who offer low-down-payment programs, down payment assistance resources, and flexible underwriting can help bridge this gap.
Policy efforts to expand homeownership access also play a role. Zoning reforms that allow more attached and smaller-lot product help reduce entry prices. Programs that support first-time home buyers, including FHA loans and conventional 97 percent LTV products, expand the pool of qualified purchasers. Builders who engage with local housing policy conversations can help shape an environment that supports both their business goals and broader expanding homeownership objectives. When policymakers and builders align on removing regulatory barriers, the resulting housing supply increases help moderate prices across both the for-sale and rental markets, reinforcing the affordability advantage that already favors buying over renting in most counties.
Monitoring Market Conditions
The buy-versus-rent equation is not static. Interest rate changes, home price appreciation, and rental market dynamics all shift the balance over time. Builders should recalculate the affordability gap quarterly for each market they operate in. When the gap narrows, it may signal a need to adjust pricing, offer incentives, or shift toward rental product. When the gap widens, builders can confidently accelerate for-sale development and increase spec inventory.
The full dataset from RealtyTrac and HUD fair market rent tables is publicly available and straightforward to incorporate into market planning. Builders who make this analysis a routine part of their strategy will be better positioned to allocate capital where demand is strongest and competition is weakest. Tracking this metric alongside traditional housing market indicators such as starts, permits, and absorption rates gives builders a more complete view of where their next project will succeed.
