Persistent but not Obnoxious, How Regularly to Follow Up?

[Will Johnston]

Two weeks ago I found a FSBO on Craigslist that I'm quite interested in, and I could use some advice on the best way to follow up.

I emailed the owner, and then texted a day or two later after no response.  They responded to the text four days later (a week ago Monday), and we scheduled a showing for Saturday afternoon, as I was out of town for Thanksgiving.

They had asked me to confirm the appointment on Friday, so I texted and after no response, called a few hours later.  Saturday morning there was still no response, so I texted again, and they said something had come up and they needed to reschedule but they would get back in touch with me Monday (today).

Knowing them following up was pretty unlikely, I texted them this morning.  Haven't gotten a response yet and am guessing this is going to be one of those long pursuits. :)

Basically, I'd love to learn from experience on the best way to pursue a lead like this.  They publicly advertised the property, so I'm assuming they actually want to sell, but they're obviously not super-motivated.  I want to follow up enough to get the deal done but not so much that I'm obnoxious/harassing. Presuming I don't hear back today, what would be your follow up plan?  In case it's relevant, I'm in a fairly hot real estate market, so if they really wanted to sell, it wouldn't be any problem to do so.

Thanks!
