Idaho has no cap on assessment increases — assessed value (and therefore tax) drifts up year over year. Budget for the drift.

⚠️ TWO LIMITATIONS. (1) OFF-MARKET — the ~$515,000 is a Zillow estimate / last data, not an active asking price. (2) The Ada County Assessor’s Terms-of-Use gate re-appeared mid-session and accepting site agreements is out of policy for this agent, so parcel, assessed value, valuation history, and tax history were NOT pulled.
tax_mois an estimate. Re-pull the county baseline if/when it relists.

County record — Ada County Assessor
⚠️ Not pulled — Terms-of-Use gate blocked the parcel/valuation/tax records. Re-pull required if it relists.
Affordability — ESTIMATE ONLY (off-market estimate; county tax NOT confirmed)
Assumptions: 6.5% 30-yr fixed, 20% down (no PMI), estimated tax ~$2,400/yr (~$200/mo — UNVERIFIED), ins ~$110/mo. The price is a Zestimate, so doubly estimated.
20% down (no PMI), if the ~$515k estimate held
- 20% down = $103,000 → loan $412,000
- P&I at 6.5%: ~$2,604/mo
- Property tax (ESTIMATED): ~$200/mo · Insurance: ~$110/mo · HOA $0 · PMI $0
- All-in (estimate): ~$2,914/mo → ~$414/mo OVER the $2,500 ceiling. Cash ~$118k (~$13k over the fund).
So even ignoring the off-market status, at ~$515k it misses both axes (~$90k over the ceiling).
Flags
- Off-market — nothing to buy today; the price is an estimate. Watch item only.
- County financials NOT pulled — Terms gate blocked the records;
tax_mois an estimate. - Over budget at the estimate — ~$414/mo over $2,500, cash ~$13k over the fund.
- 1954 3/1, 936 sqft — single bath, small; ~$550/sqft is the priciest-per-foot of the off-market trio.
Bottom line
Track only. Off-market (the ~$515k is a Zestimate) and the county pull was blocked by the Terms gate, so no real numbers yet. If the estimate holds, it’s ~$414/mo over $2,500 and over the cash fund. Pull the county baseline only if it relists.
