If $850 @ per month is your goal you might want to consider getting an $SSI check and even food stamps.

There are ways to save costs with stamps/printing.

My letters are "handwritten" - computer generated font - yellow letters with actual hand addressed invitation size envelops and a first class stamp.  

Take 5-6% for realtor, doc stamps, prorated taxes for this year, title insurance, title search, closing fee etc etc. will eat up the profit so I highly doubt you can get 25k

Essentially:  buyer-title insurance , settlement (title co.) fees, misc recording fees                       seller-basic title search, doc stamps, misc recording fees, settlement feesThis is customary for most counties, some are different

My plan is to tape each of the tri-folds, place a stamp on them, mail them out, and pray.

So whenever he tells them 'this will work', I've seen the county basically rubber stamp it 9 times out of 10.

@Tiago AlencarIf you use a first class stamp on the first batch, the addresses that don't work will return undeliverable so you can harvest those leads by skip tracing or using other means to reach the owner.

Hi All,  I own a number of rural properties of varies sizes and one of them is a very undesirable postage stamp size lot. 

Your highest bill will be the stamps which are $19.60 for 40 of them.
