Those buildings are from years ago and no longer available. That website is an old Joomla site I have that I keep because it has page 1 rankings.
I am having 2 new Wordpress websites completed with line by line custom code so that I can do anything with the sites I want to. They are truly one of a kind. One is for triple net properties nationwide and the other is for apartment investing nationwide. Those are my 2 areas of focus and I do not do anything else. Yes on those quads that is original cedar wood siding. You simply take off and put hardi-plank on and repaint.
I do not mess around with duplex's, tri-plex's , or quads anymore. I do large scale listing and sales in the commercial space. What you mentioned about 11,000 houses in Atlanta isn't worth my time. A big headache for an ultra low, low payout.
I have been doing very well and also talking with your brother. I will send some things and projections his way and you can discuss them related to multifamily.
Atlanta has great yields but you have to buy in the right spots just like other places.
Texas is good but some commercial research I have read lately points to a possible bubble in a few years with all the building and permitting going on for apartments. That could lead to occupancy drops and rent reductions or staying flat with an overbuilding bubble when supply catches up with and passes demand. The research analyzed how much permitting had picked up and expected units coming online within the next few years versus population levels etc.
