Postcards and letters.   

My agent assured me that she would confirm with the HOA.After an hour, she informed me that the HOA allowed monthly rentals.She also mentioned that the HOA documents would only be provided on the closing day.However, on the closing day, I received a letter from the HOA stating that I could only rent the property twice per year.I agree this has been a very expensive lesson.

I hired a lawyer who sent a letter of demand.

We always get the title commitment letter to review and send that to our attorney to review.

If you are in the early stages, and you have a loan contingency, you should be able to cancel and get your EMD back with a loan denial letter from your lender. 

My friend got a letter from the Lehigh Lot Owners Association.

My realtor and I will keep looking this way, just to say hello, talk for a bit, leave our contact info and a little gift :)My husband and I are residential rental owners, and I get those calls/letters/texts/emails all the time.

For example, when pha slaps you with a surprise inspection cause their system "forgot" to send a letter and then issues a 24 hr repair notice cause one outlet in the house does not work but they send that notice an hour before they come to reinspect lol, a $7k course is not going to have prepared you how to get an electrician the same day.

We are now having to involve the tenant as her lease is coming up and if we can't get the balance paid up to date then we are going to have to give her a 60 day non renewal letter. 

Most of my deals these days result from yellow lettering, inside tips on pre-market foreclosures that I can get an early jump on, or fellow agents that send me up n' coming listings that haven't hit the market yet.
