Own a masonry business; Can't decide to build or do FHA for first home?

Hoping to get some input from other contractors/owner-builts on what decision to make. I keep hearing different opinions, although only one seems to make the most sense to me.. I can't decide if I should build my first house on some land or buy a fixer-upper through FHA. My business is licensed and equipped to do the foundation, framing, and roof for essentially cost of materials + permits. I would need to sub-out the plumbing and electric. When I put the numbers on paper, buying a lot(semi-rural) and building seems to beat buying via FHA in every scenario, but I also believe i could be missing things. My plan would be to put the RV on the lot while im building and operate the buisness from the shop location. I understand the home build would take up a large chunk of time and id have to plan for it. Im curious if anyone else has been at a similar crossroads and what decisions or thought processes they went through during. Greatly appreciate any info given!

*some additional info if it helps; -Im a solo operation and bring in 100k-200k profit depending how long i spend in Florida during winter(i stay at cousin's guest house and do enough work to keep savings). -Plan would be to build ultra-modern block wall 1400sq ft home -Located in Colorado Springs/Denver area
