I'm not sure if this post technically belongs in this forum although I've sought advice here in the past, and the responses were both very intelligent and extremely helpful, so back to the well I will go once more

I am 35 years old, married with two small children (4 and 3). I'm in year 2 of my business (sole owner), and am projecting to NET over 1 million dollars this year, pre-tax. My plan is to first and foremost use this positive cash flow to scale my business so I can maintain this rate of growth, or at least try too! However, even with an aggressive growth plan in place, I'll still have appx. $500k which will appear on my tax return as income unless I come up with some forward thinking ideas now in order to minimize the tax burden which will come as a result.
Here's my initial plan. I gratefully welcome all feedback, especially the criticism, so please do not hold back if you see holes in my plan, or my head!
PART ONE: I currently have two S-corps (Biz #1 and Biz #2). In reality, I actually have a third biz that operates independently of the first two but last year I just tacked on the revenue of biz #3 to biz #1 & 2's tax returns which from what I understand, increased my tax burden for biz #3 (i.e. net income was taxed in a higher tax rate than it should have been).
Biz #1 = will net around 800k
Biz #2 = will net around 200k
Biz #3 = will net around 40k
With this in mind, he first part of my plan is to create a third entity for Biz #3 so come tax time; this business will be taxed at a lower rate. In order to make this work, I will give 51% ownership of Biz #3 to someone I trust that is in a low tax bracket - I will still retain full control of the company via written agreement.
I could do the same thing for Biz #2 but based on the corp. tax rates below, this may not be a smart move since it appears Biz #2 would actually pay more in taxes (+5%) if I completely separated it from Biz #1, and myself.
$ 0 to $ 50,000 15%
50,000 75,000 25%
75,000 100,000 34%
100,000 335,000 39%
335,000 10,000,000 34%
If my line of thinking is correct, then for Biz #3, I will save 19% in taxes or $7,600 based on a projected net income of 40k for 2016.
PART TWO: My wife and I own one home; our current residence which we bought for $160k. We still owe $90k on the note. One goal I have is to become a real estate investor. If we purchased a second, more expensive home, made it our primary residence, and then begin renting out the first home. Could I then pay off that 90k note before the end of 2016, and claim it as a deductible business expense? Would it be wise to create a LLC for my real estate company before I do this, and make my wife the majority owner so I can get the same tax benefits as I would get with Biz #3?
Thinking out loud now... Until I add more properties to my portfolio, I'm sure I'd be operating at a loss after all expenses so I guess keeping myself as the majority owner (or not even creating a legal entity for now) would benefit us more in the long run since those losses could lower my income for Biz #1 and Biz #2. Does this sound like a realistic and more importantly logical plan, or I do sound as ignorant as I feel?
Thanks again for reading!
Sincerely,
