Cut the territory into units one driver can finish in a single session, then assign each unit to one driver for a fixed window. PropertyRadar's driving-for-dollars post recommends organizing a list into groups of 30 properties or fewer, a batch one person can visit in a single day or evening, which gives you a workable ceiling on unit size.[1] Record every drive as a route, since PropertyRadar documents GPS route recording, route history, and a Member tab that displays coverage by member name.[2] Match new captures on county plus assessor parcel number before they join the shared list, because PropertyRadar's import documentation names county and APN as the starting point for a high confidence match while an address match needs the number and street plus a city or ZIP code.[4] Neither that app nor DealMachine documents an automatic street-level block, so a written revisit interval and an assignment table kept outside the tool carry the enforcement.[6]
