Build timing decision: build early-2027 vs wait for the family-gravity signal
Founder's question (2026-06-30 night): do we put the rebuild off ~3 years until we know where his brother-in-law (BIL) lands post-DMD-residency — which anchors whether the extended family stays Tampa or drifts to Miami — or push ahead and build at the start of next year regardless?
The situation
- Anchor case ("stay"): BIL finishes DMD residency in Miami in ~3 yrs → returns to Tampa, opens a practice, wife becomes office manager. This family + career stability is what gives the founder confidence to build on the current lot (1212 S Suffolk Dr, ~$1.06M).
- New hypothetical ("drift"): BIL stays in Miami. Then the family's gravity could shift south — sister-in-law + husband already half in Miami/Ft-Lauderdale; in-laws out of their hurricane-damaged home 5 yrs (insurance trouble, likely sell the lot rather than rebuild) → without that Tampa anchor they could relocate, maybe Miami.
- The brake on "drift": father-in-law won't leave before his 103-yo mother passes, and he's "not big city folk" (won't love Miami). The patriarch is a real Tampa anchor.
- Founder's stated fear: pour savings into a build → displaced to a 2-yr rental → family shifts to Miami → sell the just-built home to someone else, never got to enjoy it.
- Current living situation = the existing flood-vulnerable structure on the lot (slab 2 ft below BFE, flooded 2024); building means teardown + ~2 yr rental. (Confirm — load-bearing.)
Why this is an optionality problem, not a binary
Building a custom home is a near-irreversible ~$1.8M bet. The family-location variable resolves on its own within a few years. When a large irreversible commitment sits in front of a fork that's about to resolve, the value is in buying time, not betting the whole thing on one branch. And a custom build is the worst vehicle for a "might sell in 4 years" scenario — you overpay for personalization you won't consume, and custom homes don't recoup well on a quick sale. That is exactly the founder's named nightmare.
Regret map
| Stay (family anchors Tampa) | Drift (family → Miami) | |
|---|---|---|
| Build now (early 2027) | ✅ Optimal — enjoy the home | ❌❌ Worst case — built $1.8M custom, rented 2 yrs, sell at a loss / carry two homes |
| Wait for the signal | 🙂 Small regret — break ground ~6-18 mo later, still enjoy it | ✅ Near-optimal — only soft costs spent, hold an appreciating lot, choose Tampa-vs-Miami with real info |
Wait-for-signal has small regret in BOTH branches; build-now has catastrophic regret in the drift branch. Given the founder is explicitly worried about the drift branch, wait-for-signal dominates — unless one of the flip conditions below holds.
The unlock: the signal comes sooner than 3 years
He's framing the wait as "3 years until BIL finishes." But he doesn't need certainty (completion) — he needs the signal (intent), which lands earlier:
- Dental residents typically know their post-residency landing spot 12-18 months out (practice offers, buy-in/partnership talks, whether they're opening in Tampa).
- The SIL + in-law drift will also show its hand inside that window. So the real decision horizon is ~12-18 months, not 3 years.
Cost of waiting (the counterweight — don't ignore it)
Waiting a flat 3 years is not free:
- Daughter is 3 once — there's a "enjoy this home during her childhood" clock.
- Construction costs + rates keep climbing.
- They'd sit in the old flood-prone house through more hurricane seasons. These argue for shortening the wait / resolving the signal fast, not for a full 3-yr freeze.
Recommendation
Take neither pure side. Get fully build-ready over the next 12-18 months, hold the irreversible groundbreaking until the family signal firms up, and set a hard go/no-go checkpoint.
- All the pre-work is reversible and loses nothing if they leave: lock the design, pick the plan, clear the zoning-letter + permits, line up financing. (They're already deep in this.)
- Checkpoint (~mid-2027 or when BIL's plan is known): if "stay" is solid → break ground then (lost ~6-12 months vs "start of next year," not 3 years). If "leave" → only soft costs spent, hold the appreciating lot, decide Tampa-vs-Miami on facts.
Answer to "ideal path if we leave in 3-4 years"
Precisely the option-preserving path above: don't have broken ground. Hold the lot (it appreciates in 33629), then sell it or build-to-sell/rent when the family shifts, and buy in Miami. The worst version of "leave" is having sunk $1.8M into a custom home you sell at a loss — which is only reachable via build-now.
Flip conditions (when build-now IS right)
- Founder is honestly ~80%+ confident they stay in Tampa for the next 5+ years, OR
- The current house is bad enough (flood risk / condition) that sitting in it 12-18 more months is untenable. If either holds, build now. If neither, building now over-commits to one branch of a fork you can cheaply wait to resolve.
Open unknowns to resolve (drive the decision)
- Current living situation — living in the flood house, or already elsewhere? How tolerable for another 12-18 mo?
- How firm is the wife's "office manager for BIL's practice" as her career anchor to Tampa?
- Founder's honest gut % that they're still in Tampa in 5 years.
- When realistically does BIL's post-residency intent become knowable?
