Who lives in the mystery email house?

Around 8 years ago I sent myself an email with just an address in it. No names, no details, just an address. 

8 years on I'm wondering what made me send it to myself in the first place but more importantly, who lives/lived there at the time?

Now as an important side note, I have to stress that around that time I was using my Gmail account as a sort of notepad for everything. I've been busy across the afternoon weeding out stories I'd saved for my breakfast radio show years ago, shopping lists for the week, horse racing tips (and I don't really gamble) and lots of things from years ago that looking at now, don't make a lick of sense. For example: 

30.12.2017 A reddcoin wallet address string but it doesn't say where the actual wallet is stored. Online? Phone app? No idea.

08.03.2012 dttagmgga As the subject line. Nothing else in the email. WTF?

21.10.2011 An email with the subject line 'Standard Disposal' and nothing else in there at all. What was I disposing of? 

07.06.2013 The mysterious address in Deer Park I emailed myself. And here in lies the mystery because looking at the pictures of it online, I don't think I've ever been there.. 

I mean I'd remember the roses growing out of the bathtub wouldn't I?

And this color scheme doesn't fit any memories of friends lounges anywhere.

So why did it warrant being important enough for me to send to myself? According to the real estate timeline it last sold in 2007 so that rules out any of my friends buying it.

OTHER POSSIBILITIES?

-It was the residence of the guy who traded his Soarer for my Rx7. The year matches roughly but he would have filled out his part of the sale form with his address, why did I need to send it to myself then? Was I going to send him something later?

(I picked up the Soarer in May that year, so what did I find that I was going to mail him? And if it was him, why didn't I put the name in the reminder?)

-A family friend? I've asked a couple if they've ever lived in Deer Park. Maybe it's someone I've promised to visit but still haven't after 8 years! (Edit, friends got back and confirmed no they never lived there..)

-Some other strange reason that now escapes me? Did someone rent this, invite me to something, ask me to post something (eBay maybe?) or something else?

Anyone have any clues? Is this your house? Solve this minor mystery for me, cheers.

A DAY LATER

After texting a few friends and getting some interesting replies back, including:

'Where?'

'What are you doing now Al?'

'Not a chance, no.'

'Why?'

'You probably bought something for your RX7 there' (I didn't)

It turns out the address belongs to an old friend from school! She no longer lives there (and hasn't for a long time) but at least part of the mystery has been solved. I still don't know why I emailed it to myself, unless I was planning to send her something/turn up out of the blue/confuse myself 8 years later? Who knows.

Onto the next strange email - does anyone know what DTTAGMGGA is supposed to mean?
