FHA for 19 Year old

[Isacc Lightbourn]

I understand that FHA loans are for first time home buyers typically and work great with house hacking. I want to buy my first house hack a year from today but my credit history is a bit new. I started it last year when i turned 18. My question is, how much longer to I have to build it for a mortgage lender to approve me ? It's a good score in the 720s. The only problem is that it is a short credit history.
