Availability and responsiveness
... are two important qualities of a Charleston real estate professional (and for anyone providing quality customer service).
An employee of Boeing called me yesterday wanting to know where Boeing employees were moving to in the Charleston area. I told him that I had already helped one Boeing employee find a home in Mount Pleasant but there were many other nice areas to consider including Summerville, Daniel Island and West Ashley amongst others.
Since he was considering relocation to Charleston to work in the new Boeing facility, he wanted to get preapproved for a mortgage by talking with a mortgage lender and I told him that I would have one of my preferred lenders give him a call and that I looked forward to helping him find a home when he was ready to move to Charleston.
Anyway, I called a lender and got voice mail, I then emailed and also called again two hours later and got another voice mail so I thought I had better try someone else. I also got voice mail but this time, the lender called back within minutes so we talked briefly and she was going to contact him right away. In the meantime, after about 4 hours, the first lender finally returned my call. (Better late than never.)
It's very understandable that there are times that you cannot respond quickly to all the phone calls and emails that you get in a day. Just last week, I was taking an all day course for certification by the National Association of Realtors (NAR) as a Short Sales and Foreclosure Resource (SFR) and all the Charleston real estate agents attending had to turn off their phones, blackberry's and other berry's they might have had so the ringing, buzzing and whatnot didn't disturb the class. And at the breaks of course, everyone rushed outside to check voice mails and emails.
I had told all my clients with active deals pending that I would be unavailable most of that day and did my best to catch up with everything at the end of the day. It's simply my approach to customer service which is to treat clients the same as I want to be treated. And that is to reply to all inquiries in as timely a manner as I possibly can whether I am busy showing homes to a client or busy doing anything else.
So how do you find a Charleston real estate agent who is both available and responsive.
The quick and (self - serving) answer would be that you just found him 
... but here's an idea for you.
Contact a dozen different real estate agents and inquire about a very inexpensive property or about a rental. I would think that most agents wouldn't even bother to respond because they wouldn't make much money helping you in either situation. But the agents that did respond are agents that you can be sure will be both available and responsive to you if and when you become their client.
