Find a custom home builders FAQs

Manufactured homes roll out of the factory on a permanent steel chassis that meets HUD codes and lets you move the entire structure later. Modular homes, by contrast, arrive in sections that a crew sets on a permanent foundation, just like a stick‑built house. If you want the durability, customization options, and traditional financing of a site‑built home—but still appreciate factory efficiency—a modular build is the better fit.

Adding a modular wing usually runs 10% to 15% less than building a standalone unit. You’ll save on site work and keep the footprint smaller, yet still gain the extra square footage you need. Because modular pricing is tied to square feet, trimming size is the quickest way to trim cost without sacrificing quality.

Yes, modular homes retain their value if built and maintained well. Appraisers use the same criteria for modular and stick‑built homes, so a well‑maintained modular home keeps pace with the local market. Boost value further with buyer‑friendly upgrades—think high ceilings, efficient HVAC, and durable finishes. Those touches help your investment stay competitive for the long haul.

Once the modules hit your site, crews usually need four to six weeks to set and finish the home. Counting design, permits, and site prep, plan on four to six months from contract to move‑in. Stay in close touch with your builder to keep the schedule on track and tackle any hiccups fast.
