Is It Cheaper to Rent or Buy in the San Bernardino Mountains (2025)?

By Theresa Grant, Real Estate Broker | Team Owner | Theresa Grant & Associates Real Estate Partners

Deciding whether to keep renting or buy this year comes down to today’s interest rate, your target home price, insurance realities in our fire-prone areas, and your time horizon. Here’s a clear, local-first way to compare costs for Lake Arrowhead, Crestline, Running Springs, Big Bear, and Twin Peaks.

Snippet Answer: Stack up your annual cost to rent against your annual cost to own (PITI + HOA/road + maintenance + insurance + taxes − principal build-up − tax benefits) using 2025 rate quotes—and include wildfire insurance scenarios common in our mountains.

1) Gather the right inputs

• Mortgage rate & points: Use your actual quote (credit, down payment, points).

• Property taxes (CA): ~1% base plus local bonds/assessments.

• Insurance: Price both standard HO and, if required, FAIR Plan + DIC.

• HOA/road/lake rights: Add dues and any special assessments.

• Maintenance: Budget 1%–1.5% of value/year for snow, decks, roofs, septic.

• Closing costs & PMI: Amortize over the years you expect to keep the loan.

2) Do the apples-to-apples math

Annual Rent Cost = Monthly rent × 12 + renter’s insurance + expected rent increases.

Annual Own Cost = Principal + Interest (today’s rate)

• Property tax

• Homeowners + FAIR/DIC if needed

• HOA/road/lake dues

• Maintenance
  − Principal paid in Year 1 (wealth building)
  − Tax benefits you actually use (ask your CPA)

If Annual Own ≤ Annual Rent for your planned hold period—and you have solid reserves—owning usually wins.

3) Mountain-specific swing factors

• Wildfire coverage: Some addresses require FAIR + DIC—price both paths.

• Winter realities: Snow removal and higher seasonal utilities affect the ownership line.

• Access & rules: Private roads, septic, and STR regulations can add costs (or income); model them.
