Personally, I will be trying an A2 invitation size yellow letter next month for the first time.

Approximate size of the rooms are 300 sq.ft. in Atlanta (Decatur area)

They also don't provide the income that real-estate can.I'm interested in purchasing a small-medium sized multi-family property.

The property is good sized, new (5 years old), and in exceptionally good school district.

Depends on size and leverage.

I would estimate  $1,200. to $1,500. for that size door. 

I transfered my job to Houston in 2013 bought a turn key in 2014 for $154K (twice the size of LA house) and have been itching to explore the real estate investing world.Lil prep work I've been reading REI books, watching podcasts (flipnerd & BP), YouTube videos, and recently been getting out to network.

What size lot are you looking for?

Rich Weese as a good sized complex in Garland.

I still have a lot to learn before even considering a project of that size!
