Current tenant present when giving new tenants tours

[Charles Campbell]

My wife and I are self managing a townhouse and we are currently in the process of looking for new tenants because our current tenant's lease ends in August. So far I've been coordinating tours for prospective tenants around the schedule of my current tenants to make sure I'm not entering the property without the current tenants being home.  But coordinating my current tenant's schedule with my schedule (I work full time) and my prospect's schedule gets tiring and inconvenient for me and my prospects at times.

Do I need to make sure my current tenant is present while trying to find new renters and giving tours? Am I over stepping my bounds by telling the tenant I'd prefer, on occasions when its more convenient, to enter the property to show prospects, even if they are not home?
