STR Arbitrage Weekly: 3 Cities Where the Numbers Actually Work (May 2026)

Regulation weather: May 12–19, 2026

One deregulation event and two new bans landed this week — here's what changed.

Boise, ID — full deregulation (GREEN). On May 12, Boise City Council voted to repeal its entire STR ordinance (Title 3, Chapter 22). 1 Existing city licenses expired May 18; no license is required after that date. Idaho House Bill 583 takes full effect July 1, 2026, preempting all local STR regulation statewide — cities will not be permitted to ban, cap, or require permits. Note the gap window: city rules are already gone, but HB 583 is not yet in force. Boise is effectively ungoverned on STR right now, which creates legitimate entry opportunity but also the theoretical risk of emergency city action before July 1. If Boise is on your radar, move fast or wait for July 1 certainty.

Birmingham, AL — trending RED (vote still pending). A proposed ordinance would ban STRs in all single-family residential zones, impose a 1,067-unit citywide permit cap (roughly 1% of residential units), require 1,000-foot spacing between STRs, and mandate noise monitors and police record checks. 2 Final vote was pending as of May 19. If the ordinance passes as written, roughly 748 of 1,815 current listings would have no legal path. Do not sign a lease in Birmingham until the vote is finalized.

Mountainside, NJ — full ban. The borough enacted an ordinance banning all STRs of 30 days or fewer, with fines up to $2,000 per day.

Simi Valley, CA — chose regulation over ban. The City Council voted unanimously on May 11 to permit and tax STRs rather than ban them outright. Starting January 1, 2027, a city inspection and permit (~$741/year) will be required. A narrow win for operators in an otherwise tightening California market.

This week's 3 city picks

The following cities cleared all four hard filters: population 100k–800k; ADR × 60% occupancy exceeds long-term rent × 1.35; regulation is GREEN or YELLOW; at least one operator disclosure or peer case study in the past 12 months. All P&L models use the 3% split-fee structure (available to self-managing hosts without property management software). The 15.5% host-only model — mandatory only if you run PMS software — is shown as a comparison column where relevant. 3 4

City 1: Savannah, GA

Safe to start in the next 30 days? YES — with one mandatory pre-signing check (see regulation section).

Snapshot

Metric	Value
Population	~148,000
2BR median LTR rent	$1,756/mo 5
Average daily rate	$204–$304/night 6 7
Average occupancy	45%–67%
Active listings	2,576
Regulation status	🟡 YELLOW — STVR certificate required

The ADR spread between sources ($204 from Airbtics trailing 12 months vs. $304 from AirROI's current data) matters for your underwriting. Model at $204 if you want conservative numbers; use $250 as a midpoint realistic case. The 67% occupancy from Airbtics is a market median — your first unit, without reviews, will start closer to 40–50%.

Top 2 submarkets

Historic District / Victorian District — highest ADR, walking distance to River Street and Forsyth Park. STVR density is high; your listing needs a differentiator (parking, design-forward interiors, pet-friendly).
Starland District / Midtown — near SCAD (Savannah College of Art and Design) and Memorial Health hospital. Lower entry rent (~$1,350–$1,500/mo for 2BR), growing demand, less listing saturation. Better for Unit 1 if you want lower initial risk.

Full unit economics — sample 2BR at 60% occupancy (18 nights/month)

Line item	Amount
Gross revenue (18 nights × $204)	+$3,672
Airbnb host fee (3% split-fee)	−$110
Net revenue after platform	$3,562
Monthly rent	−$1,756
Utilities (electric, gas, water/sewer)	−$220
Internet	−$60
Cleaning (7 turns × $135)	−$945
Supplies / maintenance (~5% of gross)	−$184
Net monthly cash flow	+$337

Under the 15.5% host-only model, the same unit nets approximately +$1,312/mo at the $300/night ADR midpoint, or roughly +$100–$200/mo at $204/night. The 3% split-fee model at the conservative $204 ADR produces the $337 figure above. Savannah is the only city in this analysis where arbitrage remains meaningfully positive under both fee structures. 5 6

Regulation — 🟡 YELLOW

Savannah requires a Short-Term Vacation Rental (STVR) certificate. STVRs are permitted in the Historic District, Victorian District, and Mid-City District. 8 Key restrictions: maximum 4 adults for units with 2 bedrooms or fewer; maximum 2 adults per bedroom for larger units. In the TN-2 Streetcar District, only owner-occupied STVRs are allowed — arbitrage operators cannot use this zone. Verify the specific block's zoning classification before signing any lease. Chatham County is also reviewing its STR ordinance; if your target property is in unincorporated county land (not city limits), confirm separately.

Permit steps: Apply for STVR certificate through the City of Savannah; verify Historic District preservation eligibility for the specific address; confirm the unit is not in a TN-2 zone.

Risk callouts

Historic preservation rules may restrict exterior modifications (signage, lockboxes, furniture staging through windows)
St. Patrick's Day (March) — second-largest in the US — and spring break drive a booking surge, but summer is the sustained peak
Savannah rent declined 5.86% year-over-year as of May 2026, which is favorable for lease negotiation 5
No city-named multi-unit operator disclosure was found in this research cycle. Charleston, SC (same region) shows STR premium above 300% per AirDNA — closest peer validation available 9

Furnished Finder / mid-term signal

Memorial Health and St. Joseph's/Candler hospitals generate year-round travel nurse demand. A 2BR furnished unit on Furnished Finder in Savannah can command $1,800–$2,100/month with zero cleaning turnover and zero Airbnb fees — useful as a fallback during low-season months (November–February) when STR occupancy drops.

First 90 days playbook

Target Starland District 2BR at or below $1,500/mo — negotiate a 12-month lease with a 60-day STR rider clause
Apply for STVR certificate immediately after signing (processing time 2–4 weeks)
List on Airbnb with introductory pricing 15% below comparable listings to accelerate reviews; target 10 reviews in the first 6 weeks
Add Furnished Finder listing simultaneously; price at $1,900/mo for 30+ day bookings as occupancy insurance
Month 3: reprice Airbnb to market rate; evaluate moving to Historic District for Unit 2 once you have 15+ reviews as a portfolio credential

City 2: Fort Collins, CO

Safe to start in the next 30 days? YES — strongest ADR in the entire candidate pool, regulation clear.

Snapshot

Metric	Value
Population	~170,000
2BR estimated LTR rent	$1,500–$1,800/mo (market estimate)
Average daily rate	$252/night 9
Average occupancy	65%
Active listings	2,391
Regulation status	🟡 YELLOW — STR license required, no cap

Fort Collins has the highest ADR of all 15 candidate cities at $252/night — higher than Savannah's conservative estimate and significantly above every other secondary market in this cohort. Colorado State University (CSU), Rocky Mountain National Park (RMNP) gateway access, and a dense craft brewery ecosystem drive three distinct demand segments that don't perfectly overlap seasonally.

Top 2 submarkets

Old Town / Downtown — historic walkable core, 20+ craft breweries, highest ADR and occupancy. Premium entry rent; target units 2–3 blocks off the main drag to get walkability without top-tier rent.
Campus West / CSU area — parent and faculty visitor demand during academic year, lower entry rent (~$1,400–$1,600/mo for 2BR). Better cash flow on paper; occupancy softer in summer (students leave).

Full unit economics — sample 2BR at 60% occupancy (18 nights/month)

Line item	Amount
Gross revenue (18 nights × $252)	+$4,536
Airbnb host fee (3% split-fee)	−$136
Net revenue after platform	$4,400
Monthly rent (midpoint, $1,650)	−$1,650
Utilities	−$220
Internet	−$60
Cleaning (7 turns × $125)	−$875
Supplies / maintenance (~5% of gross)	−$227
Net monthly cash flow	+$1,368

Important caveat: Fort Collins 2BR LTR rent was not confirmed from a primary source in this research cycle; the $1,500–$1,800 range is a researcher estimate based on regional comparables. The P&L above uses $1,650 as a midpoint. Before signing, verify current 2BR asking rents on Zillow and Apartments.com for specific Fort Collins zip codes. If rents are closer to $1,800, net cash flow drops to approximately +$1,218/mo — still strong. 9

Regulation — 🟡 YELLOW

Fort Collins requires a Short-Term Rental License under Municipal Code Chapter 15, Article XVIII (§ 15-640). 10 Both primary-residence and non-primary-residence licenses are available — arbitrage operators (who won't be living in the unit) need the non-primary STR license. A life safety inspection is required before a Certificate of Occupancy is issued. Licenses renew every 2 years (annual renewal deadline June 30 regardless of application date). Note: Old Town North neighborhood removed non-primary STRs from its zoning as of July 2025 — verify the specific address is not in this sub-zone before signing. No citywide cap on STR licenses currently.

Permit steps: Apply for non-primary STR license through City of Fort Collins online portal; schedule life safety inspection; confirm property address is not in Old Town North exclusion zone.

Risk callouts

Colorado statewide lodging tax applies on top of Airbnb's occupancy tax collection — build ~5–8% into your P&L sensitivity analysis
Larimer County introduced a mandatory STR renewal fee effective January 1, 2026 — confirm current fee amount before filing
Winter occupancy dip: December–February sees reduced demand as RMNP closes to casual visitors; CSU semester break overlaps. Budget for 35–40% occupancy in these months
AirDNA named Fort Collins / Johnstown a top emerging STR market in April 2025 9 — this means more operators are entering; don't assume current competition levels persist 12 months out

Furnished Finder / mid-term signal

CSU generates steady faculty and researcher housing demand. A furnished 2BR near campus listing on Furnished Finder at $2,000–$2,200/mo for 30-day stays can bridge December–February occupancy gaps without the cleaning overhead of nightly STR.

First 90 days playbook

Confirm 2BR rent on Zillow / Apartments.com for your target zip; run your own P&L at the actual rent before signing
Verify address is outside Old Town North exclusion zone; apply for non-primary STR license
Schedule life safety inspection for week 2 after lease signing
List 10% below Old Town comparables to generate early reviews; focus photography on RMNP proximity and brewery walking-distance claims
Add Furnished Finder listing at $2,000+/mo targeting CSU visiting faculty; use 30-day bookings to fill the December trough

City 3: Chattanooga, TN

Safe to start in the next 30 days? WAIT — verify your target property is in a qualifying zone before committing.

Snapshot

Metric	Value
Population	~187,000
2BR median LTR rent	$1,459/mo 11
Average daily rate	$163–$207/night (dual-source range) 9
Average occupancy	50%–61%
Active listings	1,123–2,065 (source discrepancy)
Regulation status	🟡 YELLOW — STVR certificate, zone-dependent

Two independent data sources give materially different ADR readings: Airbtics shows $163/night at 61% occupancy; Sean Rakidzich's 2026 arbitrage analysis gives $207/night at 50% occupancy and claims 20%+ cash-on-cash returns. 12 The discrepancy likely reflects different data periods and different listing filters (Airbtics captures the full market including low performers; Rakidzich appears to focus on higher-performing subsets). Model with $170/night at 60% occupancy as a conservative but realistic base.

Chattanooga's genuine competitive advantage is EPB (Electric Power Board) gigabit internet — the first city in the US to achieve citywide gigabit coverage — which actively markets to digital nomads and remote workers. This is a demand segment that tourist-first cities like Savannah cannot replicate.

Top 2 submarkets

North Shore — across the Tennessee River from downtown, Coolidge Park, Frazier Avenue retail. Highest tourist appeal, premium ADR. High listing density means review count matters more here.
Southside / Main Street — Chattanooga Choo Choo district, proximity to EPB fiber hub, craft food scene. Attracts remote workers and young professionals. Lower entry rent, lower listing density, faster review acquisition.

Full unit economics — sample 2BR at 60% occupancy (18 nights/month)

Line item	Amount
Gross revenue (18 nights × $170)	+$3,060
Airbnb host fee (3% split-fee)	−$92
Net revenue after platform	$2,968
Monthly rent	−$1,459
Utilities	−$200
Internet	−$60
Cleaning (7 turns × $115)	−$805
Supplies / maintenance (~5% of gross)	−$153
Net monthly cash flow	+$291

Under the 15.5% host-only model at $170/night, cash flow turns negative (–$91/mo). Chattanooga only works if you self-manage without PMS software and stay on the 3% split-fee. 11 The $291 margin is thin — a single occupancy month at 50% instead of 60% costs approximately $170 in lost revenue and can push the month negative. Chattanooga requires active pricing management, not a set-and-forget approach.

Regulation — 🟡 YELLOW (zone-restricted)

Chattanooga requires a Short-Term Vacation Rental (STVR) certificate, effective January 1, 2026. 13 The critical distinction for arbitrage operators:

Owner-occupied homestays: allowed in commercial zones and within STVR overlay districts
Absentee / non-owner-occupied rentals: allowed only in commercial zones that permit hotels

Arbitrage operators are by definition absentee — you are renting a unit you don't live in. This means your target property must be in a commercially zoned area that permits hotels. Most residential neighborhoods do not qualify. The STVR overlay districts are not available to non-owner-occupied operators. Tennessee state law (2023) preempts local STR bans, which is why Chattanooga has any STR market at all — but it cannot override Chattanooga's zoning-based restrictions on non-owner-occupied units.

This is why the answer is WAIT: verify the specific address's commercial zoning classification before signing the lease. A residential address in Chattanooga — even in North Shore or Southside — may be ineligible.

Permit steps: Confirm property zoning classification with Chattanooga's planning department; apply for STVR certificate at chattanooga.gov; post certificate inside the unit and upload photo to renewal application.

Risk callouts

Margin sensitivity: the $291/mo net assumes exactly 18 nights booked. At 16 nights (53% occupancy), cash flow is approximately $0. At 15 nights (50%), it's negative
Dual-source ADR discrepancy ($163 vs. $207) is unresolved — actual performance depends heavily on listing quality, location, and dynamic pricing discipline
Potential expansion of the STVR overlay district northward (discussed June 2024) could eventually open more residential zones to arbitrage operators — monitor chcrpa.org for updates
Realtor.com reports median 2BR rent at $1,800/mo, versus Apartments.com's $1,459 — if you encounter a landlord pricing at the Realtor.com median, the economics become marginal 14

Furnished Finder / mid-term signal

Erlanger Health System, CHI Memorial, and Parkridge Medical Center generate steady travel nurse demand. At $1,800–$2,000/mo on Furnished Finder, a Southside 2BR can match STR revenue without nightly cleaning. Given Chattanooga's thin STR margins, mid-term rental as the primary strategy (with STR as overflow for peak months) may outperform pure STR arbitrage.

First 90 days playbook

Pull the property address from Chattanooga's zoning map; confirm commercial zone classification that permits hotels before any lease negotiation
If zone qualifies, negotiate a 12-month lease at or near the $1,459 Apartments.com median (not the Realtor.com $1,800 median)
Apply for STVR certificate; list on Furnished Finder simultaneously at $1,900/mo
Price Airbnb listing at $165/night initially to build reviews; aim for 15+ reviews before month 3
Month 3: run both platforms actively; use Airbnb for weekends/peak periods, Furnished Finder for 30-day fills in shoulder months (November–February)

Platform risk: what changed since January 2026

These aren't scare items — they're operating costs you need to price in.

Chargeback liability now falls on hosts. As of July 2025, Airbnb's payment terms make hosts financially responsible for guest chargebacks, including on completed stays where the host has no access to the guest's payment details. 15 16 Build a 1–2% chargeback reserve into your monthly P&L.

AI-generated evidence banned for damage claims (effective April 20, 2026). Hosts must submit verifiable, unaltered evidence for any damage claim. 16 In practice: photograph every room with timestamps immediately before and after each checkout. Use a structured check-in/check-out process, not ad-hoc photos.

Property blacklisting by prior owner history. Airbnb's AI monitoring can permanently ban a property address based on a previous host's violations, with no effective appeal path. 17 For arbitrage operators: before signing a lease on any unit that previously had an Airbnb listing, search the address on Airbnb to confirm it's listable. This takes five minutes and can save you an entire lease cycle.

Occupancy collapse in overleveraged markets. Multiple r/airbnb_hosts operators report occupancy dropping from 70–90% to 20–40% in markets they describe as "famous cities." 18 The three cities above were selected partly because their demand drivers (SCAD + military + port tourism in Savannah; CSU + RMNP in Fort Collins; EPB nomads + outdoor recreation in Chattanooga) are more diversified than pure tourist-season markets. That doesn't make them immune — it makes them more resilient.

HOA and condo board prohibitions remain the #1 acquisition trap. Before signing any lease in a condo building or HOA community, get a written copy of the HOA's STR policy. Verbal assurances from landlords are not binding on the HOA board. 19

The fee structure decision you need to make before listing

The 3% vs. 15.5% host fee choice is the single largest variable in STR arbitrage math — larger than ADR differences between cities. 3

The rule is straightforward: if you manage listings manually without property management software (Guesty, Hostaway, Lodgify, etc.), you can use the 3% split-fee model. If you connect any PMS, Airbnb forces you onto 15.5%. For a single-unit operator just starting out, do not connect a PMS. Manual management with Airbnb's native tools keeps you on 3% and improves cash flow by $350–$675/month depending on your ADR. The PMS upgrade makes sense at scale (4+ units), not unit one.
