how did you know you were ready to ttc?

I've met so many wonderful people who are ttc, and all of them had very different lives when deciding to start to ttc. So I'm curious to know how all of you decided it was the right time? me and my fiance are looking to start a family in the next few years, but first want to own a home instead of renting, & have a good amount put away in savings. As time goes on though I feel like there's more and more that I would love to do to be more prepared for starting our family, but it seems as if there's never really a good time! so how did you know? I'm Hoping it might shed some light on everything & figure out what's right for us
