I max a 403b and traditional IRA...is there a way for me to add my duplex rental income to a pretax retirement account without treating myself as an employee?

See the following.https://www.irs.gov/retirement-plans/plan-participant-employee/amount-of-roth-ira-contributions-that-you-can-make-for-2018Also, earnings on non-deductible IRAs will be subject to taxes once distributed.

Tax Cuts and Jobs act.According to the Memphis Business Journal These programs include: •$200 million in increased compensation: Two-thirds will be allocated to hourly employees by advancing the 2018 annual pay increase to April 1 rather than the normal October increase date.

If the employer thinks the employee is valuable, he or she will often share useful information like this.

@Andrew Ellis and @Sean McDonnell one thing I haven't seen brought up is the affects of the loan payment on your employee contribution. 

For starters, I prefer dealing with attorneys and bad employees over insurance! 

You are probably learning how to be a good employee, not REI, while mounting loads of debt which will make the road to financial freedom that much harder to navigate. 

They are not employees, just good folks that can get the job done here in Cleveland. 

(One employer does have about 1,000 employees though) I feel the rental market will continue to be this way for years to come.2) Rental rates on this building in my opinion are VERY low. $325 for a one bedroom (twelve total) and $360 for a two bedroom (eleven total) WITH water/trash included.

Since then, we have hired a team of almost 30 employees who have made drastic improvements to the site and have launched a lot of new features for both pro and non-pro members.
