DECISION (founder, 2026-07-13 14:36 ET): STAY PUT. "It's the right move for all our scenarios — move to Miami, build here, buy a new home. Builds our net worth the most in the near term too." Sell-and-rent branch closed. Lot-watch offer declined ("No. It's all good.") — available later if the shape itch returns. The 6/30 architecture stands: stay in the house, hold the lot, get build-ready, wait for the family-gravity signal.

Rent affordability + sell scenario (2026-07-13)

Companion to [[2026-07-13-rent-buy-build-interim-decision]]. Founder asked: what can I afford in rent · does renting accelerate net worth · what does SELLING do if I switch to renting.

Verified baseline (Monarch live pull 7/13 + June pulse canonical model)

• Net worth: $1.666M (Jul 5 pulse; +$48.7k in June, largely market-driven)
• Liquid: $262k Wealthfront HYSA + checking float
• Invested: ~$675k (Wealthfront taxable ~$460k incl. Nasdaq-100 direct, retirement ~$159k, Schwab joint $40k, misc)
• House: 1212 S Suffolk Dr — Zillow est $1,039k · Rocket mortgage -$415,622 → equity ~$623k
• Housing carry: Rocket payment $4,527/mo (Apr–Jun avg $13,579.53/3; likely escrow-inclusive = P&I + tax + insurance — confirm split) + TECO ~$327/mo + Frontier ~$96/mo
• Income (June canonical): ~$31k/mo (Mammoth + phData W-2 + Gusto + div/interest)
• Recurring spend ex-one-time: ~$18.5k/mo (INCLUDING the mortgage payment) → true savings margin ~$12.5k/mo best-case
• ⚠️ Raw Monarch Apr–Jun summary shows income $65.9k / expense $76.7k / savings −$10.9k — do NOT use raw; Gusto paychecks are tagged Transfer (undercounts income) and one-times distort (the $12.5k June check). Canonical model per finance-pulse SKILL methodology is the ground truth here.

Q1 — What can he afford in rent?

• Sticker ceiling (30% of income): ~$9k/mo. Not the binding constraint — everything in the Tampa family-rental class is "affordable."
• Binding constraint = the savings floor. Rule: keep true monthly savings ≥ $8–10k.
  • Scenario A (rent + house sits empty): rent is fully additive to the $4.5k carry → cap rent ~$3.5–4.5k/mo. Total housing ~$8–9k/mo for one lived-in home — inefficient but NW still compounds at ~$8k/mo savings + market.
  • Scenario B (rent + rent the house out): incremental cost = rent_in − rent_out. If the house rents near what they pay, ≈ wash → comfortable band widens to ~$5–6k/mo. Landlord hassle + flood-zone insurance as a rental = the price.
  • Scenario C (rent + sell): see Q3 — the $4.5k payment disappears; rent replaces it roughly 1:1.

Q2 — Does renting accelerate net worth growth?

Honest answer: renting itself accelerates nothing — staying put is always the cheapest housing. What renting protects is the actual accelerators:

• $262k stays liquid (build-ready) and $675k stays invested — June's market move alone (+~$49k) exceeded a year of rent.
• Skips the ~8–10% round-trip transaction costs of an interim buy and the premature $1.8M build lockup.
• Model: NW growth = savings margin + market returns + (house appreciation − carry). Renting dents the savings term by the incremental housing cost; Scenario B neutralizes the dent; Scenario C swaps the house term for portfolio returns on the freed equity.

Q3 — What does SELLING do?

Mechanics: ~$1,039k (Zillow est) − 6–7% selling costs ($65–73k) − $415.6k payoff ≈ $550–560k net cash. Primary-residence MFJ exclusion shields up to $500k of gain — need their cost basis to confirm fully tax-free (likely, not verified).

Monthly: kills the $4,527 payment + owner maintenance → recurring spend drops toward ~$14k; a $4–5k rent replaces it ≈ monthly wash, while ~$550k moves from land+structure into investable assets (+$22–33k/yr at 4–6%, more with his equity allocation, with volatility).

The strategic cost — the real decision: selling the house = selling the build lot. The entire 6/30 architecture (hold, get build-ready, wait for the family-gravity signal) assumed the dirt stays. So "should I sell?" reduces to: would you build on THIS lot if the family stays Tampa?

• If yes → don't sell. Scenario B (rent it out) keeps the option alive and the tenant pays the carry.
• If the lot is fungible → selling is the strongest pure-NW move of the three: no carry, no landlord risk, maximum liquidity, and full flexibility on BOTH branches of the family fork (re-buy the right dirt wherever the answer lands — at future-market prices, the one real risk).
• Note: sell-now is also the mirror-image insurance against the 6/30 nightmare (build → family leaves → forced sale). It pre-pays that regret at today's prices.

Valuation flag: $1.04M is a Zillow estimate on a flood-damaged structure on a nonconforming 68-ft lot — the value is substantially LAND; actual sale could differ meaningfully in either direction. Comps before deciding.

Recommendation shape (sent)

Rent (per the parent note) + the sell-vs-rent-out call hinges on lot conviction, not spreadsheet math — the numbers say all three sub-scenarios keep NW growing. Offered: comps + rent estimate for the house, and the basis check for the §121 exclusion.

UPDATE 14:20 ET — founder killed rent-out; fork is now STAY vs SELL-AND-RENT

Founder (14:20): rent-out "doesn't make sense" for them. Real fork = stay in the flood house until build/Miami vs sell now → rent → buy with clarity. His question: does freeing ~$500k+ to invest for ~3 years beat holding the lot in future buying power? His macro: housing can't keep growing; economy "heating up"; deflationary pressures coming (population, robots).

The framing sent: sell-to-rent = a 3-year pair trade (short housing, long equities).

• Leverage insight: holding = 1.67x levered Tampa RE ($1,039k controlled / $623k equity). Appreciation/decline hits the full $1.04M. Holding = levered long the class he's bearish on; selling = unlevered long the class he's bullish on. Self-consistent to sell IF he holds both views.
• 3-yr scenario band: RE +3%/yr → hold gains ~$96k · flat → $0 · −3%/yr → −$91k. Sell $550k invested: 6% → +$105k · 10% → +$182k · −10% → −$150k. Certain cost: ~$70k selling friction (11% of equity) + later buy-side closing. Spread ±$150-250k — real, not life-changing vs $1.67M NW + $12.5k/mo savings.
• Non-market deciders (sent as the real basis): (1) 3 more years in the flood house = the biggest unpriced term; (2) lot conviction reads as gone soft — if he wouldn't build on THAT lot in the stay-branch, holding is an unloved levered position; (3) sequence risk — 3-year money can't be 100% equities; blend ~50/50 equities/T-bills, which shrinks the expected edge. Sell for life reasons; the trade is bonus.
• Macro honesty flagged: his two views are in tension (economy-rips scenario usually brings rate cuts → housing up too); robots/population = 10-20yr force, 3-yr Tampa RE = rates + FL insurance + migration (insurance drag genuinely supports his housing caution).
• Lean sent: if flood-house exit desire + soft lot conviction both true → sell and rent, blended proceeds. If lot still the dream → hold; $70k is the price of changing your mind twice.
• §121 note (not sent, for the record): both his branches sell while the house still qualifies as primary residence (2-of-5 rule), so the MFJ $500k gain exclusion is safe in either; the dangerous path was rent-it-out >3yrs then sell — now moot since rent-out is dead.
• Offered: a Michelle-readable decision page with scenarios (joint call).

UPDATE 14:31 ET — CONVERGED ON HOLD + the lot-swap instrument

Founder's clarifying facts (14:31): the lot is "ideal, not a dream" — right location. Michelle's acceptable set = exactly 4 neighborhoods: Culbreath Bayou (current), Culbreath Isles (she grew up), Beach Park, Palma Ceia. Their slice: side street within already-low-traffic Culbreath Bayou = kid safety. The dislike is the DIRT SHAPE: undersized for the neighborhood, narrow+long ("shotgun" proportions — matches the vault's 68-ft nonconforming fact). Re-entry: "difficult to get a home in here… buying our way back in would be at a premium." He also penciled rent at $8k/mo and read the trade edge as ~$150k = doesn't move the needle.

Ray's response (sent):

• At $8k rent the trade goes negative: ($8k − $4.5k) × 36 ≈ $126k extra housing spend vs +$105-182k expected on the freed $550k → net ~zero-to-negative before sequence risk.
• The decisive reframe: the lot is a scarce entry ticket to the only 4 acceptable neighborhoods, with premium re-entry. Never go short a market you're forced to re-enter at a premium. → HOLD.
• The real problem is location-right/shape-wrong → instrument = lot-for-lot swap: hold the current ticket, watch the 4 neighborhoods for a ≥75ft lot or teardown candidate, sell-and-buy in one motion when it appears. Continuously long the micro-market, no re-entry premium, shape fixed.
• Fallbacks noted: 68ft IS buildable (7 width-verified plans from the June 2026-06-10 curation, 3 coastal drive-under) — shotgun isn't forced; principal paydown = quiet forced savings on the stay path.
• Offered: standing lot watch (listing alerts, 4 neighborhoods, wide/teardown filter).

Net state: sell-and-rent branch is dead on his own facts + numbers. Standing plan reverts to the 6/30 architecture (stay, build-ready, wait for family-gravity signal) UPGRADED with the lot-swap watch as the shape fix. Decision page offer superseded — converged conversationally.

Open

• Founder: go/no-go on the lot watch build
• Confirm Rocket payment escrow split · cost basis (matters again only if a swap candidate appears)
• The 6/30 open asks stand: gut % Tampa-in-5yr · flood-house tolerability · Michelle career anchor
