If you really don't value your agent's ability and think you can do it better, it's likely best that you 1) interview more to find one that you do trust, 2) go through the listing agent, directly, if you're that comfortable with handling your side on your own, or 3) maybe get your license so you can control your side of negotiations with the proper tools needed (MLS access with agent info, showings, contracts, tax records, uploaded listing docs like surveys, disclosures, broker assistance for questions, etc.).

As far as the practicality, you want to look for homes with somewhat separate spaces, and theres an app now called padsplit that I've not used but have heard good things about to help with the management nuance of it.  

It's a crock.You need to pay off all debt and get your finances under control.

Selling Your Home Now: This could be practical as you’d split closing costs with your ex and avoid the obligation to refinance at a higher interest rate.

I believe that to be the most common practice at least in my market.

Some sponsors are mitigating this risk by raising their own pref tranches from their own investor base, thereby giving them control over the terms.In a strong up market it’s likely that rent growth and strong demand will drive up income, thus driving up value, which supports the ability to take out the pref.  

But it wasn't until a pivotal moment that I realized the importance of taking control of my financial future.

There are clearly downsides - the investments are even less liquid than active real estate, they are completely out of your control and they are long term in nature.  

Setting standards just to deny people is BAD practice, BAD business, and ILLEGAL.

You have control over it but it will be a lot more work.
