I have found several vacant lots in my local area that I am interested in.  I have the information I need to send letters to the owners of said lots.  My problem is that I am unsure of what to write. Do I send a one p...

Others have simply created a new listing and had the seller notify guests about the change.

I have had luck with doing direct mail marketing for some of my past clients that wanted a certain area or neighborhood, you'd be surprised at how many sellers don't want to deal with showings and everything else that goes into listing a home. 

I send a text to introduce myself and ask if we can answer any questions about the listing or to support them in finalizing their booking.We follow up with an e-mail reiterating the same information.  

And when you do have a list is cold calling the best way to reach owners as direct mail would most likely go to their tenants and not the owner if not occupying the property?

I would also contact your insurance company as well and notify them of the claim of theft. 

Then I mail a very simple handwritten letter and usually get north of a 30% response rate.  

We (the buyers) notified our agent that the property must also be move-in-ready.We received images of the interior and exterior which showed the property in move-in ready condition/what appeared to be minimal to no deferred maintenance issues, the listing said "property inmove-in condition/turn-key".

Bandit signs, cold calls/texting along with direct mail is the method most people use.
