It was a wonderful experience all the way through. No matter what issues arose they stayed true to their word and acted with complete respect and professionalism. Our home is exactly the way we expected it to turn out. We would absolutely hire them again and again!!"

"I had an aluminum door canopy that pulled completely away from the house due to the weight of excessive snow. Might Be Helpful explained how the canopy could be re-installed and made stronger, even showing me the hardware to be used. I am a rather exacting customer but Might Be Helpful got the canopy up and it looks great--just like I wanted. A bit of re-painting was done; the job site was left neat and clean; and a dried-up can of paint was disposed of for me which I quite appreciated."

"Preston of G-1 Plumbing performed the services and addressed the toilet & drain problem. He was unable to stop leak(made it worse) & submitted his recs to Choice Home for review. I was unable to understand Choice Home's response regarding the faucet leak. Their review stated faucet needed to be replaced BUT it was under "builder's warranty." I built this home in 2005. There is no "builder's warranty" now. I cancelled the proposed work order & paid out-of-pocket. A Friend, who was familiar with my builder and knows faucet components, came to my home, adjusted/cleaned the faucet cartridge and stopped the leak. The CHW tech, Preston, is conscientiuos, however, IMHO lacked the knowledge & experience to stop my leak. Home Warranty Companies, at least in my area, hire owner/operators who need the work to build their business and are NOT the most experienced/knowledgeable & are willing to work for less money. In my experience, Home Warranty Companies want the CHEAPEST resolution, not the BEST. I would recommend G-1 Plumbing for most plumbing issues."

Home Building FAQs, answered by experts

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

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.

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home. 

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

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.
