With issuing the Notice to Leave form, at the same time as offering the new tenancy, and doing so the required 2 months prior, we find that is probably the biggest incentive for the tenant to sign. As with most agencies, we do try to go for greater than 6 month leases, and have them end in the more traditionally high rental periods. With 6 month tenancies, it is often a bit of a shock for a tenant to receive information about renewal, when in their mind, they just moved in, so the longer tenancy seems to help with that as well. Your comments about staff changing, is one that all business work hard at addressing. Generally, if a business has the challenge of a new PM, not lasting long, usually its for reasons outside the business's control, and if the policy and procedures are in place, then that can make life easier for others in the business, as well as the new PM get settled. We had a run a few years ago, and a "not young" PM, only lasted around 3 months, as her daughter with children had a car accident in Cairns, so being a mum, off she went to help. Thankfully our owners understood, and gave us the time to find a replacement and get them settled. Communication between the parties is very often the key to good outcomes.
