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. 

one take away is to alway treat a potential investor partner like a tenant.. you want a full credit report and a back ground check.. cost you probably 100 bucks to do this.if the potential partner gives you some static like this is insulting etc.. you then know your answer up front.However again I want to stress this can and does happen with a lot of frequency your just brave enough  to post it...

So even if they are on one policy or all on one, the same situation of frequency could occur.

It depends on your goals, what returns you'd be getting on your property, and many other factors.Timing and frequency also make a huge difference.

As for the free converter boxes, the FCC is happy to provide them, as they'll make much more money off the freeing up of the spectrum frequencies than they'll spend helping people convert.

Or what if insurance got more expensive because a higher frequency of natural disasters?

What types of crime are you guys ok with, and not ok with and at what frequency and distance?

There is one true test to determine if an investment is passive: once you have made the investment, from that point forward, any activity made by you, regardless of the type, duration, frequency, etc of that action, has no bearing whatsoever on the outcome of the investment.
