Working from home is realistic nearby — roughly 100% of homes report broadband at 100/20 Mbps or better, gigabit reaching a real share of homes.

Distances are straight-line, so the drive is longer. Internet and neighborhood figures describe the surrounding town — and the rent benchmark, wildfire rank, and tornado count the wider county — not this park’s own lots. The fair market rent is apartment-style rent (HUD’s area benchmark), not this park’s lot rent. Rent limits are not legal advice.

For residents
- Water billing: if your park bills water by submeter, Oregon caps the usage rate at your utility's rate (ORS 90.572), and your bill should show both meter reads and that rate. Check the math free with the water submeter calculator, or read the Oregon water-billing guide.
- Paying rent: ask the park office how they take payment. Parks that run on Lot Sidekick hand residents clear, itemized rent and water bills.
- Thinking about moving here? What to ask a park before you rent a lot, and what lot rent covers and how it goes up.
