Traditionally, P/L will be split based on the amount each partner contributed.

That is the very definition of "highest and best use" and will make a lot of folks $$ while also contributing 8 affordable units to the city of Chicago.  

@Ayana MoraliIf you are depositing non-retirement funds in a 401k, you would do so as contribution (e.g. from your wages if you have a 401k through your employer or if you are self-employed with no full-time employees you can set up a Solo 401k and make contributions based on your self-employment income. 

I am a college student that wishes to delve in real estate (particularly rental residential properties) soon and I know I can learn a lot here and hopefully I can contribute something as well :) Cheers!

There are some immensely successful people that continue to contribute priceless content.

. - The most effective thing I can think of as a non-attorney and non-CPA (so check this before you rock this) would be to have a Joint Venture agreement between your company and the potential partner's company in which your company contributes money to each project in exchange for repayment of principal amount (the loan for rehab) and 50% of the net proceeds of the sale.

@Steven Cruz I'm not super familiar with a 457b, but from some quick research, it sounds like you can contribute the normal maximums to both independently.

In addition, if you are self-employed with no full-time employees you may wish to consider opening a Solo 401k instead of a self-directed IRA as it has several advantages over an IRA LLC such as much higher contribution limits, direct checkbook control (i.e. no need to have the account at a specialty trust company), ability to take a 401k loan, exclusion from unrelated debt finance income tax with respect to investment in real estate acquired with non-recourse financing, etc.In addition, please note if you purchase debt-financed real estate with your IRA, unrelated debt finance income tax should apply to the income attributable to debt-financed real estate held by your IRA.
