One of my goals is to go through my past tax returns, and figure the ROI my rental properties with taking into account the tax savings (I typically calculate the ROI on net cashflow at the end of the year)I have a W2 so I generally aim to maximize my pre-tax accounts - 401k, HSA, IRA to a backdoor Roth IRA, 529My "losses" would be passed forward since I don't qualify as a RE professional nor have active RE losses.

If IRA owns the property wouldn’t all rental income have to go directly into the IRA?  

Investing in a mortgage fund should not have tax implications for your Roth IRA since the investment is passive. 

Quote from @Kwanza Price: Thanks Chelsea for your reply.I mostly wanted to understand what the experience was like and if you have any advice for setting up an LLC/IRA?

For example, if tax minimization is a priority and you're already maxing out your employer sponsored 401(k)s, you can look at deferring self-employment income through SEP IRAs and an individual Defined Benefit Plan. 

Some people use their 401(k), IRA, Pension, TSP, RRSP to invest.

I have a 401k, IRA, and pension in place to help me achieve retirement quicker, however I definitely feel the squeeze on a daily basis and always feel like I'm living paycheck to paycheck.

Also, have you looked into self-directed IRAs for real estate investing?

Some people use their IRA to fund fix and flip's and keep the profit in them tax free. 

You have kids - do a 529 plan and max it out You will retire one day - max out your 401k yearly, IRA, Roth IRA (or backdoor to Roth IRA)You will have health expenses one day - max out your HSA From here I'd invest in Real Estate.
