Whole House Commodity Index - April 2026

Despite unimpressive housing demand and higher mortgage rates, significant inflation has impacted the RoMac Whole House Commodity Index over the last 30 days. The Index surged 3.3 percent to $54,607- the highest cost since August 2022 - and a notable 4.4 percent increase compared to April 2025. Tight labor due to restrictive immigration policies, higher fuel costs, and limited trucking availability appear to be the primary catalysts for these increases. Mills and manufacturers are working to align supply with current demand, as uncertainty persists around the direction of home sales in 2026.

Builders are facing renewed cost pressure as the Index climbs to $54,607, reflecting increases in fuel, labor, and key material inputs.

Mortgage rates continue to trend upward. According to Freddie Mac, the average 30-year mortgage rate increased from 5.98% on February 26 to 6.11% last month and currently stands at 6.37%. Early optimism around improved housing starts in January (up 7.2%) and increased home sales in Florida (up 4.8% through February, according to Florida Realtors) has waned, as mortgage applications dipped 0.8% in the first week of April. The Iran war has contributed to higher fuel costs and increased uncertainty. Alongside immigration and tariff issues, this is weighing heavily on the housing market.

Outlook

Looking ahead, roofing prices are expected to increase based on prior manufacturer announcements, and many other sectors are signaling upward pressure due to rising energy costs. It’s important to note that the issue extends beyond diesel fuel. Mills and manufacturers in the building supply industry rely heavily on electricity and natural gas, and those costs are rising just as sharply.

The Iran war is dampening enthusiasm in the spring housing market and creating broader economic challenges. Higher fuel and energy costs will disproportionately impact construction due to its heavy reliance on these inputs. This environment points toward a slower market paired with rising prices, hallmarks of stagflation.

What builders need most right now is resolution: an end to geopolitical conflict, along with clarity on immigration and tariff policies. Without it, the summer market could prove challenging for builders and developers across Central Florida.

About the Index

The RoMac Building Supply Whole House Commodity Index is based on wholesale costs of the base components required to build a 2,200-square-foot wood-frame home with a concrete stem wall in Central Florida.

The Index includes:

• Foundation, metal, concrete, block, stucco, and cement

• Wood framing, siding, sheathing, and trusses

• Roofing, drywall, insulation

• Windows, doors, trim, garage doors, and most building hardware

  
  

It does not include décor, electrical, plumbing, mechanical, landscaping, or labor.

Because the Index uses current wholesale costs, it serves as a strong indicator of building price trends over the next 30–45 days.
