Some drywall patching, painting, exterior damage fixing (mostly rotten soffits/fascia boards), and a lot of junk removal.

Today I learned about listability.com, realquest.com, why national change of address (NCOA) is important when choosing a list provider, and "horsey letters" mail piece that supposedly gets better response rates than post cards and regular letters.

If need be, I could leave one of the units vacant, get mail there to prove as my address, and receive mail there and still probably cashflow, but that's not ideal. 

Tenants gets a copy mailed to them. 

They also require you to send direct mail.  

He asked for my last name - "since you know my last name" he said.Would you give out that information to try and build rapport or just remove that property from future mailings?

For starters:Learn how to execute a direct mail campaign (i.e. - finding the right list, sorting it adequately, sending out the right message and handling the responses as they come in).Learn how to do proper due diligence (figure out all the relevant details about each property, learn how to establish a ballpark value for each parcel and make appropriate offers that will actually allow you to make money in the end).Learn how to list and sell properties (understand where to list them, how to attract the most attention, how to offer a value proposition that buyers actually want, all while acknowledging that some properties will inherently sell a lot faster than others... and this is okay).There's a lot more to be said about the process as a whole - but this is the "10,000 foot high" overview of what you'd need to figure out in order to operate a feasible land investing business. 

Zach, The company I mentioned was purchasing this $20M building and they had mailed this proposal to my mentor hoping that he would become an equity partner. 

Now they all go on youtube, they used to send out mailers and newsletters back in the snail mail days and for whatever reason, back when I was in high school in the late 80's/early 90's I must've ended up on some mailing list as someone susceptible to buying into doomsday economic theories, because they sent them addressed to me, to my parents house all of the time!

How did you come up with the mailing list?
