Blind offers/Mailers

Hello, I am new to this. Currently have single family home rentals, looking to jump into MHP’s. I have been reading, learning, researching while looking for MHP’s to invest in.

I have read the 10/20 Investment System and have a couple of questions. How do you make a blind offer - having received no financial information? Also what is a process/wording used on mailers. There are a few I would like to contact - not sure the best way to do that.

Any information would be greatly appreciated - as I am acting as a sponge right now - trying to soak everything up I can!

Thanks in advance!
