Also I'm not looking for electronic or wifi connected, just a mechanical unit. 

No cell phones, no texts, no online portals and rent payments, no electronic signatures, some email, newspaper ads and a lot of door knocking (I can almost feel some of you more seasoned PM vets nodding out there). 

Send me a direct message and I can send you FREE electronic copies of my 2 books.

Post on your social media accounts, go into other Facebook groups and post, bigger pockets, craigslist etc etc etc....Always be Marketing and Networking! 

@Christian Nachtrieb I don't do the collecting, However all of my properties that require an HOA payment collect from me either via an Automatic withdrawal (ACH) on the 1st business day of the month, or I personally do a monthly electronic transfer into the HOA bank account.  

There shouldn't be that many using the service if you pre-screen well -- I rent to the first tenant that fits my criteria, so I don't have a ton of fall-through.I do also think that checking their social media profiles and check their references as part of the application process is a good idea, as well.

You might be able to drive some small amount of organic traffic using social media but it's very little and not worth it.

For this reason, most statistics about international migration into Des Moines cited in the news media are probably referring either to Polk County or to the Des Moines metro as a whole (Polk, Dallas, Warren, Madison, Guthrie).

I personally do not like electronic payment system as they can be open to abuse by tenants.

Being young, you're probably tech savvy and can figure out social media marketing for a mentor.
