Arizona RV park snowbird T-12 modeling
Model October–April peak and May–September trough separately — permanent lenders underwrite trailing 12 months, not January × 12. Desert private water systems need capacity review; $35–$75/pad/mo utility opex belongs in bridge memo.
Colorado River/Yuma corridors overlap with Arizona MHC — outdoor hospitality and lot-rent are different NOI streams; do not cross-apply cap rates.
Arizona RV park bridge loans underwrite snowbird seasonality — October–April fill rates on Phoenix, Tucson, and Colorado River corridors must appear in trailing 12-month DSCR, not peak-season broker pro forma. Desert parks with private water need capacity review and $35–$75/pad/mo utility opex in NOI; municipal water stubbed to expansion pads refi faster at regional banks.

Arizona RV park segments and basis bands
| Segment | Geography | Basis band | ADR / occupancy profile |
|---|---|---|---|
| Phoenix metro snowbird | Maricopa, Pinal exurban | $1.8M–$3.2M | Oct–Apr peak; May–Sep trough |
| Tucson / Oro Valley | Pima corridor | $1.2M–$2.2M | Snowbird + winter visitor demand |
| Colorado River / Yuma | Yuma, La Paz, Mohave | $1M–$2M | Strong Oct–Mar fill; desert utilities |
| Flagstaff / high country | Coconino fringe | $900K–$1.6M | Opposite season — summer peak |
Maricopa County snowbird parks at $2M–$2.8M on 80–120 pads — May–September occupancy may drop to 25%–40% in extreme heat. Private well utility $55–$90/pad/mo in desert pro forma.

Arizona diligence checklist
- Well logs and water capacity — private systems on desert parcels
- Septic per-pad capacity — expansion limits on exurban acreage
- Summer occupancy trough — T-12 must include May–September
- Heat infrastructure — shade, pool maintenance, electrical load at peak temps
- Pad electric amperage — 50-amp for full-time snowbird rigs
- ADWR water rights — verify on rural acreage before expansion
Exit and refinance path
Arizona snowbird RV refi requires summer trough in trailing P&L — Midwest and Mountain sponsors accustomed to winter off-seasons must model inverse seasonality (May–September vacancy).
SBA 7(a) refi (Maricopa snowbird): Illustration: a $1.85M loan at 7.25% on a 25-year payment is $13,372 a month. Coverage on $16,800 NOI is 1.26x, not 1.28x. That loan replaces the $1.632M bridge only if the $220K holdback is already off the books. SBA reviewers still want May–September occupancy in the file, not an October–April year. Two snowbird seasons after the work is the safer path before you apply.
Yuma / Colorado River corridor: Strong Oct–Mar fill but Apr–Sep desert heat compresses T-12 — parks at $1M–$1.8M basis with well/septic need ADWR capacity review before refi. Utility opex $55–$90/pad/mo vs $20–$30 municipal.
Tucson / Oro Valley: Moderate snowbird demand with more year-round residency — refi timeline 16–18 months vs 20–24 months Phoenix pure snowbird. ADR $38–$52/night blended.
Flagstaff high country (inverse seasonality): Summer peak / winter trough — opposite pro forma from Phoenix; do not cross-comp DSCR models. Coconino fringe basis $900K–$1.4M.
50-amp and shade PIP: Desert parks require shade structures and electrical load upgrades for full-time snowbird rigs — budget $3K–$5K/pad in holdback before bridge close. Cross-program: mobile home park loans Arizona shares utility diligence in Colorado River corridor.
Heat infrastructure reserve: Pool, misting, and $1,500–$2,500/mo incremental electric in peak heat — mandatory in T-12 before refi. Guide: RV park refinance.
Pinal exurban (Apache Junction/Queen Creek fringe): $1.6M–$2.4M on 70–100 pads — Jun–Aug at 30%–42% occupancy in T-12. Mohave/Bullhead City: Colorado River recreation supports +$10–$14 ADR premium over inland Yuma — $4K–$6K/pad PIP on legacy 30-amp infrastructure at 110°F+ electrical load.
Oro Valley/Pima snowbird blend: Higher permanent-resident mix (35%–45% year-round) reduces May–Sep trough vs pure Phoenix snowbird — refi timeline 16–18 months. Flagstaff inverse seasonality: Summer peak parks require opposite T-12 model from Maricopa — never cross-comp DSCR pro formas between high-country and desert assets in same portfolio memo.

Arizona RV revenue underwriting
Separate annual camper revenue from transient hookups on Arizona RV parks — banks exclude seasonal overlap from permanent debt sizing. Monsoon and habitation heat stress HVAC scope — Phoenix exurban comps do not price Tucson basin ARV. Pedestal electric and septic capex on older parks belongs in the bridge budget, not post-close surprise.

Arizona house prices, jobs, and permits
The all-transactions index was 731.21 in the second quarter of 2026, compared with 724.44 a year earlier. The gain is about 0.9%. The series is not seasonally adjusted. The first quarter of 1980 equals 100. See FRED AZSTHPI.
A 0.9% change in house prices will not carry a snowbird park. October-through-April occupancy will. If a seller annualizes January, discard that annualization before you talk about price.
Unemployment was 5.6% in August 2026 and 4.9% in August 2025. The rate is not seasonally adjusted. See FRED AZURN. August is also the trough for Phoenix parks. A higher August jobless rate and a half-empty park can land in the same trailing year. Underwrite both. Do not blend them into one cheerful statewide line.
Permits covered 4,266 new private housing units in August 2026, up from 2,523 in August 2025. Not seasonally adjusted. See FRED AZBPPRIV. New houses in Maricopa do not replace an RV pad. They do give a winter visitor another way to stay for a month. Model that choice when you raise nightly rates.
Fuel prices and the drive into the desert
U.S. regular gasoline averaged $4.354 a gallon in the week of October 5, 2026. The week of September 28 it was $4.465. See the EIA gasoline and diesel update. This is a national pump average, not a Phoenix station price.
Snowbirds drive to Phoenix, Tucson, and the Colorado River. A one-week move in the national average is not a demand forecast. It is a reason to keep a shoulder-month case in the trailing 12 months. Do not mark every pad full from October through April because fuel ticked down for seven days.
Bridge, coverage, and the rental loan that is not this park
Arizona bridge loans from Jaken Finance Group are 8.99% to 13.5%, for 12 to 24 months, up to 90% of the purchase price, with a close in 7 to 10 business days.
The Maricopa illustration is 68% of price plus a separate improvement holdback. The 90% cap applies to a qualified purchase. It does not mean you can ignore the summer trough.
On a park file, coverage means net operating income divided by the loan payment. It does not mean the residential DSCR loan. That loan is 5.75% to 10.5% and closes in about 14 business days. Use DSCR loans Arizona for houses. Use bridge, then a bank or an SBA 7(a) loan, for the park.
An SBA 7(a) loan can acquire, refinance, or improve real estate and buildings. The maximum 7(a) loan is $5 million. See SBA 7(a) loans. The $1.85 million figure in the illustration is under that cap. The cap is not an approval.
Maricopa illustration, payment check
The price stays $2.4 million. The bridge piece is $1.632 million, 68% of price, at 11.625% interest-only. Interest on that piece is $15,810 a month. If the $220,000 holdback is also outstanding at the same rate, the combined balance is $1.852 million and interest is $17,941 a month.
Stabilized NOI is $16,800. That covers $15,810 with little room, about 1.06x. It does not cover $17,941. If both balances are out at once, the stated NOI does not pay the interest. Spend the holdback down, or bring cash, before you call the park stabilized.
The $1.85 million takeout at 7.25%, on a 25-year payment, is $13,372 a month. Coverage is $16,800 divided by $13,372, or 1.26x. Interest-only on $1.85 million would be $11,177, and coverage would be 1.50x. Say which payment you mean.
The takeout is about $2,000 short of the bridge plus the full holdback, before costs. It does not cash anyone out. Month 20 fits a 24-month maximum and misses a 12-month term. Use the longer bridge if the work must finish before a snowbird season and you still need a full trailing year after that.
Flagstaff parks peak in summer. Do not drop this Maricopa interest schedule onto a high-country file. The season is upside down, and the water system is a different problem.
