Concerning notices to remove a tenant with an expired lease or increase there rent, I'm fairly sure it's half the length of time of the frequency that they pay rent.

I would like to start by doing 500 mailings per month every 4-6 weeks, and after a couple mailings, hit another segment or tone back the frequency, based on volume.Thanks again!

In my experience volume and frequency is the key determining factor to if you get any deal or not.

Who is consistently doing mailing and what volume and frequency would you say is the sweet spot?

This is new code but they have a lot of issues with the frequency of tripping.

Is there a page on BP.com that lists all the books mentioned (and frequency) by each podcast guests' Final Four questions "what's your favorite real estate/business book"?

I'm a huge proponent of the land value tax, but there are a few things that you need to understand about it.The biggest is that you are taxing rent and that means you need to tax patents, government monopolies or licenses, frequencies, etc.

I do agree with you @Jim K. that it is an easy fix that does not take long to do but the problem I have is the frequency at which I have to do it.

You already defined your use, but budget and use frequency come into play.   

Its not rental friendly and is already more expensive to install and will be replaced at higher frequency (not cost efficient).
