Background: We purchased a second-hand house in 2000 and took possession in 2014. Although we've lost over 30,000 USD, we consider it a necessity and have no intention of selling the property. The house is now over 10 years old, and parts of it tend to malfunction from time to time. The previous owner installed subpar materials during the renovation, so I've been constantly repairing and maintaining it. As a result, I've decided to rent a temporary place for half a year and then renovate the house. However, I'm worried about encountering potential pitfalls during the renovation process. I have no experience with home renovations and would like to seek advice from v friends on how to find a reputable renovation company. What are the key factors to consider when selecting a renovation company, and what should I be mindful of to avoid common mistakes?
