In Arizona, the cure period for seller to respond to BINSR is:

3 days is incorrect because Arizona law specifically provides a 5-day cure period, not 3. This timeframe might be confused with response periods in other states or with the buyer's initial inspection period.

10 days is incorrect because Arizona's statutory requirement is 5 days, not 10. This longer timeframe may be confused with inspection periods in other states or with default response times for different types of contingencies.

While contracts can specify timeframes, Arizona law establishes a minimum 5-day response period for BINSR that cannot be contractually shortened. Contracts can extend this period but cannot reduce it below the statutory minimum.
