Long-Term vs Short-Term Rental: The Investor Math in 2026
If you're sitting on a property and trying to decide whether to run it as a long-term rental or as a short-term rental, the answer depends on math most listings spreadsheets quietly skip. Gross rent looks bigger on the STR side. Net cash flow tells a different story once you fold in operating costs, vacancy, and the tax treatment that follows each.
Gross rent isn't the comparison
A two-bedroom condo in a strong urban market might rent long-term for $2,800/month — $33,600/year. The same unit listed on Airbnb might pull $250/night × 75% occupancy = $68,400/year. Looks like an easy 2× win for STR.
It's not. STR gross gets eaten by direct operating costs LTR doesn't have.
STR cost structure people forget
Cleaning per turnover ($85-$140 in most markets), supplies (linens, paper goods, soaps), platform fees (Airbnb hosts pay 3%, VRBO higher), occupancy and sales taxes (often 10-18% combined depending on jurisdiction), higher utilities (everything stays on year-round), insurance (STR-specific policies are 20-40% more), and self-management or property management (15-25% if outsourced).
After those, a $68k STR gross often nets to $34-$42k. Closer to the LTR number than the gross suggested.
The vacancy assumption
Underwriting STRs at 75% occupancy is the default in pro forma spreadsheets — and the default is often wrong. The honest national average for a competently run, mid-tier STR is 55-65%. Top performers hit 75%+. New listings without reviews often spend 6-9 months in the 35-50% range.
Run the math at 60%, not 75%, when you're underwriting an unproven listing.
Long-term rental is more passive than it looks
The boring win for LTR: stable cash flow, lower operating overhead, fewer late-night messages from guests asking how the AC works. Hand it to a property manager at 8-10% and you're truly passive.
Trade-off: weaker upside. You're capped by what the local rental market supports.
The tax piece people miss
Long-term rentals are treated as passive income. Losses are mostly trapped at the entity level unless you're a real-estate professional or your AGI is low enough to qualify for the $25k active loss allowance.
Short-term rentals (average guest stay under 7 days, material participation) can be classified as active. That's a big deal — it can let losses (including bonus depreciation) offset W-2 income. Talk to a CPA before you assume this applies to you.
When STR wins
Markets with travel demand year-round, strong nightly rates relative to LTR rent (a 2.5×+ ratio is the threshold most pros use), and operators who actually run it like a business — pricing, listings, reviews, ops.
When LTR wins
Markets with weaker tourism, regulatory risk (cities tightening STR rules — see New York, Honolulu, increasingly San Diego), or owners who want the cash flow without the operating load.
