+# 019: Sale value bonus for owning another property
+
+2026-10-15, issue #49. Builds on decisions 012, 013, 017 and 018.
+
+## Decision
+
+- **Optional `ownedBonus`** in `src/data/production.ts`: a property that must be owned, its
+  label, the bonus and its own source. Used by two Money Fronts: Hands On Car Wash (+35%
+  Counterfeit Cash) and Smoke on the Water (+35% Weed Farm), both from gta.wiki.
+- The bonus joins `valueBonus` and raises the nearby value, rounded down to whole dollars per
+  unit like the named Acid Lab product (decision 017). Heat does not turn it off: no source says
+  it does.
+- **Far value is an estimate (decision 013).** No source says how the front bonus combines with
+  the +50% far sale. LSOS adds the percentages (base × 1.85), the lower of adding and
+  multiplying (base × 2.025), and marks the far value "(est.)" with the rule in its tooltip.
+- **Only Biker Sell Missions:** the sources name only those, so nightclub goods (Cash Creation,
+  Organic Produce) keep their value.
+- **Higgins Helitours** (+10% Air Freight with a Hangar) is left out: the hangar is tracked
+  only as owned, without stock or value.
+
+## Why
+
+Adding is the lower guess, so the tracker does not promise money a sale may not pay. A separate
+`ownedBonus` keeps the upgrade-based `valueBonus` as it is; both are real cases, but they come
+from different places (an upgrade of the business, ownership of another property).
