Speaking from experience, $2k will get you about 2,000 oversized postcards.

How many hours a week should be set aside for marketing per week (relationship building, cold call, email, yellow letter/postcard)?

Are you referring to sending postcards to landlords out of state whose properties set on my criteria?

I've been watching videos on how to wholesale and I was wondering if anyone can answer just a couple of questions.1 - When sending postcards or letters to in-county and out-of-county absentee owners are the postcards/letters going to an address where no one is currently living?

The local investor, who may or may not be on BP, sent me a cheap little postcard mailer with some language about how they were interested in my property, and that they "know it has some deferred maintenance, and we have priced it into our offer already."

EVERYONE is doing it wrong.Do it yourself.That is the only way you are sure you do it correct.It is easier than you think I promise you that.Then lastly... sure the advantage of DMM is you are getting your own leads... but when you stop marketing the leads stop.Not sustainable.An other disadvantage is that when I do my walk trhoughs and walk the houses of some of our leads (that I got for free as they look for ME, not me looking for them) I see STACKS of yellow letters and postcards from competitors.... you are one of SO many sending mailers... yet they pick me when I didn't send them a SINGLE mailer.We even sit there with iced tea in my hand as they offer us cookies laugh at these poor suckers sending mailers.

I don't mind getting post cards or letters in the mail but I now receive texts all the time asking me about selling my properties. 

I have been using postcards and mailing to a very specific list using a list source list. 

You can then send do a targeted letter/postcard campaign to these property owners to see if they're interested in selling.

As far as mail, depending on what you are doing, I like to hit people with a lot of post cards so over 8 in 45 days.
