  The email thing is absolutely unprofessional. If you have time to respond to texts, you have time to respond to emails. Sorry, that's how it is. Most smart phones can pull up email on your phone.  Curt texts are a bit of a weird place. I know my mom can't text very well because of how big her hands are and how sensitive her phone's screen is. But if he's going to be texting as a major form of communication, I'd think the realtor would know better and have some way around this.  As far as not responding at all to your texts, he may not have gotten it. I sent my boyfriend a text on Friday night asking when he'd be home. He got home about 00 minutes later and asked if I had gotten his text. He had sent it 00 minutes before I sent mine to him, and didn't get it until about ten minutes after he'd walked into the house. We've also each had problems with various phones where you'd technically receive a text, but there was no notification. I'm not saying it's an excuse, because theoretically he'd keep in touch with you by other means, but text messaging is by no means a surefire way of communicating.  I think since John essentially works for you, it is within your rights to inform him that his communication is lacking and you need more. But I would do this with a phone call. Tell him his unanswered emails and cryptic text messages leave you feeling frustrated, and tell him you want to be kept better informed about what's going on. Also tell him you want him to acknowledge that he has received your messages with some type of response.  POD to this. He's working for you, you have every right to clear and open lines of communication, and that means going in both directions.
