I believe email alerts would be of help to you. I have added a web address link where you can sign up for email alerts of "Active" properties from an IDX feed from the Lawrence Board of REALTORS MLS.
These email alerts will help you keep track of "Active" listings by marking each property as a "Favorite", a "Possibility", or a "Reject". That way you don't have any doubt about whether a property is "Active", whether you have seen the property before online, and helps you organize your property search.
Let me know if you need any assistance. Just like all the other REALTORS who answered your question, I am a buyer agent who is happy to show you ANY "Active" property listing. Besides the email alerts I suggested which will benefit you, you will also benefit from my extensive research on the properties you are most interested in. Just click on "Contact" below my photo.
Best of luck to you, Andy!
