@Matthieu Miser awesome to have you on BP! Like several others on this thread, sounds like you and I have similar goals and background. I've been researching the Utah county market pretty extensively over the last several months, and although I'm not the best person to ask, I would be more than willing to share any info I have with ya!
Also, although this move might not be the most popular, I might suggest looking into summer sales this summer to build up some quick capital for your investments. Obviously you can buy real estate for little or no money down but having some capital never hurt. I just suggest it because its something I've done for four summers previous (but not this summer) and because of that I feel like I have more investing power than my peers because of it. And I did summer sales right after I got back from the mish and it was a great time for me to start, just because I was still had my work-my-guts-out attitude (which it seems you still have).
Anyways, just a thought, feel free to message me if you have any questions on the market here or good summer sales companies, I've done a ton of research on both :) WELCOME!!!
