Check out electronic billboards which are affordable compared to static printed boards.  

I do request newsletters from many websites and companies because that info does keep me up to date in those areas...

Other than direct mail, we do:1) Pay-per-click (Google Adwords, search marketing)2) Add your business to "Google My Business" - this makes you show up ON THE MAPS.https://www.google.com/business/3) Outdoor - electronic billboards are more affordable for RE investors4) Door hangers and Post-It Notes5) Car wraps - way more effective than simple car magnets6) Sponsoring events where we get a booth with banner, etc.7) In markets where allowed - Bandit Signs8) Flyers on cars in parking lots...

We've got an opening in this weekend's newsletter that we're going to offer at a 30% discount off the regular $275 price.

I have gotten a great email newsletter for years from lenders that blog about all sorts of creative solutions to investor and homeowner financing.

By certified mail or electronic?

I used to stagger rent since I rent to mostly a non-electronically-apt demographic, and it turned into them always needing until the end of the month anyway (my dates were like the 25th, 26th, etc). 

Keep electronic copies of your invoices and receipts and make sure your are running everything through a bank account designated solely for the rental.

Hankook is still ramping up and LG electronics is coming.

I would use a PDF that shows a picture of the house, if it is electronic then I would include before and after pictures.
