Jasmine Roth didn't just share why she might say no to having someone on her show, she also shared some other things that might keep a homeowner from getting cast on the network. One of the more obvious things is that there needs to be a casting call in your area. A shocking reason you might not be cast for HGTV has to do with your renovation budget. In her post, Roth specifically states that having over $150,000 for a renovation budget means you will likely want more to be done than can be handled by a team on TV. Similarly, if your expected timeline is too long, then your home likely won't be chosen for a show that can only film for around 12 weeks.
