Keep in mind that viewings demand a lot of work and goodwill from tenants. The last thing you want are tenants who think their private lives are being intruded upon or that their lives have been turned upside down. Make sure tenants feel they are respected in this process by keeping the lines of communication open. Ask him or her after each visit what went well, what didn’t and then work to improve the process. It will pay off in the long run because a home with a cooperative tenant will typically sell faster (and for more money) than one with a disgruntled tenant.
