"The work went very well, my wife and I were pleased with the prompt professional service. The price was affordable and the work was great, once finished he cleaned after himself and made sure we were satisfied. I would definitely refer this company to anyone I know who needs any home repair work. Chris met our expectations and beyond with the affordable price and high quality service along with a time frame."

"Cain was friendly, kind, and professional. I had such a small "honey-do" list, but he treated me with as if I had a remodeling contract with him! HBC is providing such a needed service to those of us who need minor repairs done around the house and we can't do them on our own. Now, I know who to call, and that will be HBC!"

Custom Home Builders FAQs, answered by experts

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

Yes, professionals offer mantel and surround customization for aesthetic appeal.

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.
