If you think you will have multiple assets or any frequency of transactions, you will find the checkbook control will be vastly more usable and cost effective over the long term than using a 3rd party processing agency.

It wasn't until I fully understood this concept of frequency before great that I really changed the game for myself.  

I don't know for sure of the frequency but it seems to be yearly - I've received a notice every year since my purchase.

Up to this point I have relied on the cleaners to let me know what supplies are low and I also drive to the units with enough frequency to note what needs to be purchased.

That might be very different in frequency for a PM.

Tell them the amount and frequency.  

I feel the best place to find investment groups in the Albuquerque area is through meetup.comHere are some of the meetups and their frequencies (Pre-COVID of course):Investing in Albuquerque - Monthly mixer (every second Tuesday) & Monthly meetup (every fourth Tuesday)ABQ Congress on Real Estate - Monthly meetup (every second Thursday)Apartment Investor Breakfast - Monthly meetup (every second Friday)ABQ REIA - Monthly meetup (every third Wednesday)Apartment Association of New Mexico - Check the events page for everything they put onAlso, I’d be happy to sit down with you and talk about the Albuquerque market if you are interested.Let me know if you have any specific questions!

What would be a good frequency to send these types of letters to these owners aka Buyers?

Sending a new mailer every 4-5 weeks is a good frequency.

They're convenient, but the price & wait was unappealing.The compiled list is in what struck me as relative level of positive references and frequency of reference - by my impression, not statistical tracking.
