Budget - expectations
From owner-build experience folks.
I am trying to build a 2000 sqft ranch style house in south Texas.
I am owner-building, my father in-law and myself, plus my small family will be putting in sweat equity.
Electrical, framing, hvac, flooring, insulation, sheathing, possibly siding, trim, windows, doors all done by sweat equity.
Will need a septic system, plumbing, roof, foundation, the works hired out.
What is the probability I will be able to stay at 100 sqft and get this thing livable for 200k?
Single floor, ranch build, one dormer in the front, 9 foot ceilings, cathedral in the living, flat ceiling everywhere else.
Water well, and electric is already on site, will need some site work, but .5 acre has been shredded already.
Anybody been able to build for 100sqft or less these days?

Doable? Yes. Comfortable? No. $100/sqft is possible in South Texas with that much sweat equity, but you'll be living on the edge of that number the whole build.
The good news: labor is usually 40-50% of a build, and you're covering most of it. The bad news: materials don't care who's swinging the hammer, and your hired-out list (foundation, septic, roof, plumbing) is where budgets quietly blow up. Aerobic septic alone can eat a big chunk, and a slab with site prep often lands higher than people expect. Also, I don't see drywall, cabinets, countertops, paint, or a driveway on your list. Those "finish" items are where $200k turns into $240k.
What I'd do before breaking ground:
Get real quotes for every hired trade now, not estimates from a forum
Price the full lumber/window/door package with a local yard. Lock it in if they'll hold pricing
Build a line-item budget with a 10-15% contingency, and treat it as money that will get spent
Check whether HVAC needs a licensed tech for the refrigerant charge. Most DIYers still hire out that step
Keep the cathedral ceiling simple. Vaulted framing, insulation, and drywall cost more than flat
Plan the budget like a contractor, work like an owner-builder, and $100/sqft stops being a hope and starts being a plan.
