I would market to mobile home owners with yellow letters and find a screaming deal. 

I am currently at 51 hours and i have filled 3 yellow pad books with notes from the BP podcast.

I intend on sending 500 yellow letters, as well as capitalizing on phone calls, drive by's, bandit signs and consistent phone marketing.

As soon as they set the appointment, they stop calling the other yellow letters/postcards.I love craigslist ads too, they are free and you will get bites from sellers AND buyers.Then there are bandit signs, which, are a topic on their own.....check local laws.Hope this helps!

Sent a hand written yellow letter, so hopefully i get a call soon.Any tips for a new landlord or how to go about following up on leads for yellow letters?

Send yellow letters to absentee owners.

I spoke with the owner 6 months ago after sending him a yellow letter, and he was looking for considerably more than I was willing to pay.

Are worthy RMLO's hard to find or is it just a matter of finding a standard mortgage broker in the yellow pages(Google)?

In NYC I think its always a worthwhile strategy to pick a few properties and focus on them   as opposed to sending out 1000's of yellow letters.  

Interesting twist--Today while getting the mail at the 'flip house' I received a 'yellow letter' from another investor attempting to buy it.
