Kendo/Kenjutsu Practitioners GIH

I’ve been thinking of buying a live katana to display in my home (and in case someone breaks in hehe). I was wondering if it was necessary to buy a iaito for practice. I’m kinda on a tight budget and I’m a little cheap.
Do you think it’s ok to practice with a live blade or is it too dangerous for someone of my experience?
(I’ve only trained in kendo for about 2 years. Admittedly, I wasn’t the best in my class. Probably somewhere in the middle)
