I would call them, tell them you're very interested and set appointment to go see the property, be ready to make an offer in person and follow up with written offer in the form of a letter. 

Second, I don't set an open house, I set an appointment, and then set additional appointments for the same time. 

I would suggest you make an appointment with an FHA lender and ask these questions.

I paid a little extra for the realtor to handle setting up viewing appointments (listing realtor would just call me and leave a message that a buyer was coming out) and a lock box.  

Creating a hardship on current tenants as landlords now post 2 Day Notices to enter to do appointments and all those other annoying things.The TRUE concern for Seattle Landlords is this.

I made an appointment with agent A and really like him.  

She is generating plenty of contacts and building great relationships but I am wondering if anyone knows about how many listing appointments per month/week I should be expecting.  

He's getting a response rate of 4.5% just 3 weeks into it and from that has made 4 appointments.

Then I told them to set up an appointment with their banker to come in and pay it off and I went with them and met with their banker in person and was able to negotiate a deal where I paid the past due payments and fees to bring them current, and also paid the next 4 months payments direct to the bank up front, and contracted to purchase the property for the payoff balance within 120 days. 

My appointments alone have generated listings worth over $9,000,000 in residential real estate just since January.
