Need Advice - Future First Time Homeowner

I am 24 years old and I’m in AZ living off of a teachers salary (around $50k). I’ve been living with my parents and saving up and have roughly $23k in savings. I get paid roughly $2300k a month. I have no debt at all. I’m interested in a Taylor Morrison home in Avondale, AZ that costs $430k+. I’m extremely new to this process and I’m looking for any kind of advice you have regarding the process of:

- home buying in general
- your experience with TM
- if I could afford the home
- payment assistant plans for teachers
- how new construction plans work (ie. the home isn’t built yet)

Thank you so much for your help. Please let me know if you need additional information in order to help.
