In my experience you don't really need more than 3 lines, its dialing too fast and your number will get tagged.

I manage with simple notes, spread sheet, even just making tags in my phones SMS to search back and find that person every 30 days.   

We (I work at Azibo, just a disclaimer) have quite robust accounting capabilities and time saving features like Schedule E generation and automated  transaction tagging rules.

I apologize if I didn't tag you.

Tagging @Scott Smith because I expect he'll have a great answer on this

Thank you for the tag brother.Hey @Randall Owens - I would love to connect and hear more about your project. 

A common trap to fall into is seeing a nicely renovated house at a reasonable price tag.

You don't magically get a tag next to your name that says Cc NOW is motivated.. oh wait... ... wait for it.. wait for it... almost... one more second ...NOW, NOW Cc is motivated, everyone send her a mailer.Silly right?

I am tagging someone that has a lot of experience in cheaper units.  

A little context: the building is structurally sound and they have done major updates such as septic, generator, and sprinkler system, and all mechanicals are recently inspected and tagged.
