Phasing decides whether you live in it or move out
A true full-home remodel — gut to studs, all systems updated, new kitchen and baths — is a 6–12 month live-out project for the homeowner. Phasing the work to allow occupancy adds 25–40% to total cost (more crew mobilizations, temporary kitchen and bath setups, dust containment between phases) and stretches the schedule to 12–18 months. Most homeowners underestimate the cost of phased occupancy until month four.
If you can move out for 4–6 months, full-home gut renovations get materially cheaper per sqft and finish 30–50% faster. If you can't move out, scope to a less-aggressive remodel (one room at a time, multi-year) and accept that the per-sqft number you get from the calculator above is the move-out scenario, not the live-in scenario.

Mechanical and electrical: the under-budgeted half of full-home remodels
Pre-1980 homes typically need a panel upgrade (200-amp service, often from 100-amp original), a partial or full PEX repipe (replacing galvanized supply lines or polybutylene), and an HVAC system replacement (existing systems are usually undersized for new open-concept floor plans and over their useful life). Together these run $35,000–$80,000 on a 2,000 sqft home — a separate "house" being built behind the visible finishes.
Quote-only-the-finishes remodel bids are how full-home renovation budgets blow up by year two. Insist on mechanical and electrical evaluation before bid finalization — your HVAC sub, electrician, and plumber should each walk the house and provide line-item bids that the GC then carries through. Skipping this evaluation routinely adds $25,000–$50,000 in mid-project change orders.
Kitchen + baths take 35–45% of total — and where finish-tier math is non-linear
In a 2,000 sqft full remodel at the standard tier, the kitchen and 2–3 bathrooms typically eat $70,000–$95,000 of the $300,000 budget — roughly 25–35% of dollars in 10–15% of square footage. The math is non-linear: moving the kitchen from standard to upscale doubles the kitchen line item, but only adds 20% to total project cost. Moving the rest of the house from standard to upscale adds another 20% on top of that.
The implication: spend the upscale premium where it shows (kitchen, primary bath) and stay at standard tier on bedrooms, secondary baths, and finishes. Whole-house upscale is rarely worth the spread on resale.

GC overhead and profit is real and skipping it is how DIY-managed projects fail
A licensed general contractor markup on subcontractors typically runs 15–25% of subcontracted cost. Homeowners managing GC duties themselves to avoid the markup (the "I'll just hire each sub directly" plan) save the overhead but inherit schedule-coordination, change-order management, and warranty consolidation responsibilities they almost never have time or expertise for. Most owner-managed full remodels run 20–40% over budget because the missing GC layer is what catches problems before they become expensive.
On a project of this scope, the GC overhead is well-spent. The right question isn't "should I have a GC" but "is this GC worth their markup" — a mediocre GC is worse than no GC; a good one is the highest-value $45,000 you'll spend.
How regional multipliers stack on full-home scope
A 2,000 sqft standard full-home remodel at the East South Central multiplier (0.88×) is about $264,000 base. The same scope on the Pacific (1.22×) is $366,000 base, $421,000 with contingency. Full-home remodels are the most multiplier-sensitive remodel type because they stack labor (mechanical + electrical + plumbing + finish carpentry + tile + painters) across many subcontractor categories, and every one of those subs is multiplier-affected.
