They could even log into the Google email account associated with the account and send questionable emails, upload photos of who knows what to Google photos, etc.. 

You can text/email/call or even see them before allowing them to move in.

I'm getting good results for our clients with postcards and some paid ads, but I'm looking at implementing cold email and cold calling as well.Any good companies to buy lists from?

Except their customer service is only through email.

I am hearing from a number of sellers (mostly developers) who are clearly being forwarded copy and paste emails from buyer agents evidenced by questions that aren't even relevant to the properties they are selling.

I'm sure if you sent an email to the WRA (WI Realtors Association) they'd give you the run down!

I have a Wynd sensor in my units (mention that we have it and it's 99.9% accurate in our emails), put it in my house rules that it is a $250 fine, and have a sign small above the detector with the same language.

Secondly, he again did not fully disclose everything and was pushing for the signature on the final closing documents, in them he has 2 seperate title agencies involved as well as a third party construction company listed as the policy holder for the insurance for the home, and the figures for sale are different from those on the sale agreement document that I did sign, with clauses included that state if the title is not free and clear that the buyer has the right to sue me for insurance purposes and to cover the silent second mortgage that I was only informed of because the title agency called me to say something was up after arranging the notary to come to me to sign the final documents (at which point I said no and had a copy of the closing documents emailed to me), and again the so called real estate agent negotiating the transaction is listed as the buyer (under the guise of being part of ushomebuyers.com, same as the agreement to sell). 

I will wait on a DM or email from Rene.

And sometimes (sorry) people have to find me on BiggerPockets as my emails are always filled with a ton of messages.But I try.
