Custom Home Builders FAQs, answered by experts

A contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.
