It's a long road if you're construction savvy, an even longer one if you're not. Consider a career in an area where's you've got more assets.
Throughout much of the country, the home inspection business is hi-jacked by agents. The client pays you, but you must appease his/her agent instead if you want the job. The client is oblivious to what's going on. Problem is that what agents want and what clients want from the home inspector are two very different things. If you get into this business, you'll likely survive only by making yourself more attractive to agents than your competition is. I'm consideration quitting this business next year, which will be 20 years in this business, on account of it. I always serve who's paying me, and agents hate me for it. They hate my guts.
