Needing advice

Hello everyone,

I am 23 and started as a GS-5. I am a GS-6 and get my GS-7 in February of 2025. I have contributed 5% to my TSP (L fund) and 5% to Roth every pay period. Do you have any tips and advice on whether I am doing okay? Also, I planned to take out a loan around May 2025 to buy my first house. Is that a good move? Should I not be looking into taking a loan out on my TSP? I'm only asking because I feel that since I'm young, I could get my TSP back up quickly, and I really want to be a homeowner.
