@Robert L.,
This is a really important question. QI failures can fall into several categories: scammers who steal money or information, ineffective operators who can blow your Exchange and get the IRS after you, weak QI infrastructures that don't have adequate insurance or safety protocols against outside fraudsters, etc.
It's a lot to navigate. Not enough people ask the questions that you're asking.
How to find a reputable QI:
- reviews and Google searches are a good starting point, but not the end of the road
- referrals from a source you trust
- call and speak to your prospective QI. Ask for proof of insurance. Ask for details about security. Ask for references. Find out where they are holding your funds.
- There are a lot of good folks on BP who have been in the game a long time and can vouch for different QIs
As for your DIY model: you can't do 99% of exchanges on your own, the IRS won't let you. It's why companies like ours exist - we are creatures of the tax code. You need an independent third party to act as QI. And, even if you could, you wouldn't want to. 1031 rules are opaque and deeply unintuitive when taken as a whole. The room for error is very large. Lots of trip wires.
Do you know what your tax liability would be if you sold without a 1031?
