Existing Home Sales (Annualized) vs 5/1 Adjustable-Rate Mortgage (ARM)

How These Two Indicators Relate

Interest rates and housing-market readings are tightly linked. The 10-year Treasury yield is the primary anchor for 30-year mortgage rates, and mortgage rates are the primary swing factor for housing affordability and demand. When rates rise, expect housing volume and home-price growth to soften with a lag of three to nine months.

The two indicators are currently moving in opposite directions. Home Sales has moved higher +0.0M from the prior reading, while 5/1 ARM has moved lower -0.1%. Divergent moves on related indicators usually flag a regime shift in progress — one of the two is leading and the other is lagging.

What Existing Home Sales (Annualized) Measures

Existing home sales measures the number of completed sales of previously owned homes, expressed as a seasonally adjusted annual rate. It accounts for approximately 85-90% of all home sales in the U.S.

At 4.26 million, existing home sales remain well below the 2021 peak of 6.1 million. The 'lock-in effect' — where homeowners refuse to give up sub-4% mortgages — continues to constrain inventory. For executives, this suppressed transaction volume affects real estate commissions, moving services, home improvement spending, and mortgage origination revenue across the industry.

Methodology: The National Association of Realtors compiles data from Multiple Listing Services (MLS) across the country. A sale is counted at closing, not contract signing.

What 5/1 Adjustable-Rate Mortgage (ARM) Measures

The 5/1 adjustable-rate mortgage (ARM) offers a fixed rate for the first 5 years, then adjusts annually based on a benchmark index plus a margin. ARMs typically start with a lower rate than 30-year fixed mortgages, making them attractive for buyers who plan to sell or refinance within 5-7 years.

At 6.17%, the 5/1 ARM offers a modest discount to the 30-year fixed rate of 6.64%. When this spread is narrow (under 0.5%), the risk-reward of choosing an ARM is less compelling — you take on rate adjustment risk for relatively little savings. A wider spread (1%+) makes ARMs more attractive. For real estate investors and corporate relocation programs, ARMs can reduce carrying costs on properties held for short periods.

Methodology: Freddie Mac surveys lenders weekly. The 5/1 ARM rate reflects the initial fixed-rate period offered to well-qualified borrowers. After the 5-year fixed period, the rate adjusts annually based on the Secured Overnight Financing Rate (SOFR) index plus a lender margin, subject to periodic and lifetime caps.

How These Comparisons Are Built

Each pairwise comparison page is statically generated from the live indicator dataset — values, trends, and source links are pre-rendered into HTML at build time. When the underlying dataset refreshes (each indicator on its own publication schedule), the comparison page regenerates automatically. ExecBolt does not estimate, model, or interpolate any reading; every value comes from the publishing agency’s primary release. For the full sourcing approach, citation format, and known limitations, see the methodology page.

For tools that translate macro readings into business outputs (DCF, runway, break-even), see the calculators page. Authoritative external context comes from the Federal Reserve’s FRED database, the U.S. Bureau of Labor Statistics, the U.S. Bureau of Economic Analysis, and the SEC EDGAR system.
