She has to pay $6,000 a semester.I want to contribute to my family someday.  

His contribution to garner the profits?

Non cash add backs make your income look better and count as a tax deduction so its the best of both worlds.You may keep the earnings or profit as "retained earnings," but its still shown on your tax returns either as 1099, W2, or distrubtion via k1.On the conventional side we add up the 2015 and 2014 totals for 1099/W2/K1's and average them for each individual business, operation, or entity or if the most recent 2015 year is worst then we'll just average 2015 by 12 months to determine your monthly income.This is done for each entity or business or property.As a side note personal contributions from the employee side to your 401k is not counted against you but the employer contribution is so when you're doing your tax planning with your accountant you may want to shift or strategically plan this accordingly depending on what income you want to show on the lending end.Hope that helps.

After diligently reading, listening, following and doing some posting, I finally feel like I have something to contribute to the general knowledge pool for beginners.

I look forward to contributing!

If you have little to none @Craig Moore perhaps you should find a mentor who you can team up with and in addition to your capital that you can contribute you can also learn the process.  

Then, once complete, begin contributing this to your real estate money.  

Some of the most successful people in business, real estate and life contribute it to their mentors along the way.A coach is someone that is paid for their services.
