I double checked my phone capture system.

I was not trying to be a prophet and see the future, however @Kevin Raye appears to have  gone on to bigger, presumably shinier objects capturing his attention. 

Visit open houses Or do more advertising than you can capture and don't worry.  

Some people are mailing 5000/10,000 + mailings a month and obviously that requires a very good system to capture inbound calls. 

Simply search for "building buyers list".Some of the best ways (other than word of mouth and capturing on your own website) are looking into public records for cash sales, trustee sale buyers (also found via public records), and networking.I would place bandit signs very low on the list of building my buyers list.

Volume mailing requires lead capture filters and systems for efficiency.

Things you can't learn without the trench conversations.Ultimately once marketing is in place and producing then set up a lead capture system that does the work of filter and categorizingThat capture system can be a voicemail system however it can also be a staff of buyers making relationships

They are generally not real estate people and will, in time, migrate they cash reserves to whatever opportunity d'jur captures their fancy.

So if they do exchange emails or phone calls separetely, the summary of the conversation/exchange could be captured and posted for BP.Or maybe the email exchange could just be copied.One last thing.

Be creative and capture their attention.
