'Your best bet is to wholesale for now- you find a super good deal (how are the yellow letters coming?)  

when i do seller carrybacks I get hammered by yellow letters soliciting the purchase of my notes. we just sold one and the buyer got a 22% apr.. 

Once the smoke clears there will be vulture investors doing yellow letters to the lot owners you can count on that. 

I just started my direct mail campaign and it took a whole Sunday (3:30-9PM) to do 200 letters and this was about as automatic as the average Joe could get:Printed Yellow letters using Officejet printer (Paper from Amazon)Printed envelopes using the same printer (Envelopes from Dollar Store)Bought 400 forever stamps from the Post Office to create the "genuine" effectStill, folding and stuffing papers was an extremely underestimated variable.

Yes I have done wholesale investing so I know how it is (bird dogging, driving for dollars, yellow letters etc.).  

Growing up, my mother and I were renters, and I vividly recall the gratitude we felt when a landlord took a chance on us, despite my mother's imperfect credit history.

Years ago I have sent yellow letters to 1,000 selected addresses in a suburb of Milwaukee.

Was it on yellow paper with red ink?

We do Self storage and deal with wasp and yellow jacket nests throughout the summer.  

 @Constantinos ZavosI had a lot of good experience with Yellow Letter HQ, OLM is good too. they suggest multiple styles of templates for you to use.
