2 Tax Rules That Could Cut Profits When You Rent Your House

The IRS allows homeowners a capital gains exclusion of $250,000 (single) or $500,000 (married filing jointly) for a primary residence, but converting a home to a rental can trigger depreciation recapture and reduce or eliminate that exclusion. Depreciation on the building (not land) is taken over 27.5 years and any accumulated depreciation is recaptured at a flat 25% rate on sale; e.g., $100,000 of depreciation yields $25,000 of recapture tax. Additionally, the two‑out‑of‑five‑years occupancy rule prorates the exclusion for non‑qualified rental periods (illustrated by a $300,000 gain with three years rented leaving $90,000 subject to capital gains tax), so owners should model after‑tax proceeds and consult a CPA before converting a primary residence to rental use.

Analysis

Market structure: Owners converting primary homes to rentals create near-term winners (single-family rental operators and property managers such as INVH, AMH, private SFR platforms) and losers (marginal move-up buyers and regional homebuilders like DHI/LEN exposed to turnover-dependent demand). If even 5–10% of would‑be sellers hold inventory as rentals over 12–24 months, resale supply tightness could add 3–7% to local listing prices, boosting landlord yields but compressing new‑build demand. Pricing power shifts toward landlords and long-term holders; listing-dependent broker revenues may be volatile by market.

Risk assessment: Key tail risks include a legislative fix (Congress/IRS guidance restoring broader proportional exclusion) or a severe rate shock that collapses housing demand; either could reverse flows in 0–12 months. Hidden dependencies: magnitude depends on mortgage rates, regional affordability, and capital availability for buy-to-rent; a 100bp move in mortgage rates materially alters economics for small landlord converts. Catalysts to watch in the next 30–90 days: state/local incentives, IRS technical guidance, and Q4 existing‑home sale data.

Trade implications: Direct trades — establish a 2–3% long in INVH/AMH (single-family REITs) to capture higher rental supply arbitrage, financed by a 1–2% short in DHI/LEN (homebuilders) where move-up demand may fade; pair trade long INVH, short DHI. Options — buy 3–6 month put spreads on XHB or DHI to hedge macro downside and sell OTM calls on INVH to finance exposure. Rotate portfolio +3% into residential REITs and -3% out of homebuilders and regional mortgage originators over the next 1–6 months.

Contrarian angles: Consensus overstresses taxation as a deal‑killer — many landlords accept deferred 25% recapture for multiyear cashflow; markets may underprice SFR yield repricing and institutional consolidation (repeat of post‑2008 SFR wave). Reaction may be underdone for REITs and overdone for small builders; unintended consequence — higher institutional SFR demand could bid up SFR REIT multiples, and political risk (tax reform) remains a 12–24 month overhang.

Key Decisions for Investors

• Establish a 2–3% portfolio long in single‑family rental REITs such as INVH or AMH within 30 days to capture likely higher rental inventory/price arbitrage; target 12‑month hold, trim on 20–30% total return.
• Initiate a 1–2% short position in homebuilders (e.g., DHI or LEN) or buy 3–6 month put spreads on XHB, anticipating reduced move‑up demand; target exit at 6–9 months or after a 25% downside move.
• Implement a pair trade: long INVH (2%) funded by short DHI (1.5%); rebalance if basis moves >10% or after IRS/state guidance within 90 days.
• Use options to hedge: buy 3–6 month put spreads on DHI (strike -10% / -20% from spot) financed by selling OTM calls on INVH (30–60 day), keeping net cost near zero to protect against rate shock.
• Monitor three specific triggers in the next 30–90 days before scaling positions: (1) any IRS technical guidance on primary residence exclusion, (2) monthly existing‑home sales/inventory reports, and (3) mortgage rate moves >50bp which would change rent vs. sell calculus.
