I see the downside and understand how non emergency calls get old but in my experience the tenants usually think highly of you when you address any issue and the frequency of calls typically dwindles the longer they stay.

California is probably best known for this practice but most states have a required or suggested frequency for reassessment and are discouraged from using the sale price as an indication of the assessment because it causes inequities (those who have purchased recently have the highest assessments).

You don't have time personally for the other deals which sets you up to wholesale those deals to other investors.As for response, it will vary on several factors:- the quality of your data (list or data source)- how often are those people being mailed to- the quality of your envelope- the style and copy of your letter - the frequency at which you mail (most investors mail once maybe twice, although in sales most deals happen after contact 5)Track your response and make small tweaks and track the improvement. 

the one I am using is a bit pricey and I constantly have to play phone tag to adjust mowing frequency.  

I was thinking mailers and wanted to know some good companies to use, frequency, radius etc.

It provides a line item detail for each payment application to principal/interest plus you can change the compounding frequency.  

We've not seen any difference in their frequency since we went to self-showings.

On another note from the aviation world.. the Austin Center had their computers in the basement.. basement flooded  ATC went down... so you had the airlines having to resort to flying like little guys.. flying VFR patterns and calling out their postions on the common radio frequencies which is NOT very common for them.Also departures were old school once an airliner was in the que and number one for take off they had to get on their cell phones and call Houston center for their IFR clearance.. this is what happens in non radar environments.. but its a testament to our aviation system that when tech goes down we can keep flying.. albeit like its 1950 but we keep going

With great frequency, a pattern like the one on your wall tends to be water flowing toward the wall instead of away the wall at the surface.

Beware.I suspect this is whats driving the frequency and stratospheric heights of 1st note increases.
