Agree with @Chris Seveney- people LOVE making their ownership structures so complicated when you can mitigate risk in so many simpler ways. 

Negotiation Challenges: Risk of under-the-table deals with other buyers.Tips: Be aware of these risks and take steps to mitigate them.

And if not, how can we mitigate roadblocks?

The more you can help investors mitigate risk, confirm their underwriting, and/or illuminate potential gains or pitfalls; the more successful you'll be.

i do think it's challenging, though, for a brand new investor with zero experience to jump right into a huge rehab with a contractor they've never worked with before.the contractor might want a larger up-front payment to mitigate their own risk, and they're not going to be interested in any kind of fancy nonsense like a 'penalty' when they know a new investor has never managed a large project before.i have also found that some contractors, including reputable ones, don't even want to share itemized bids because they just don't want to have to argue about the individual line items. 

If you clear your head to the idea that it is possible to lose money, but that there are ways to mitigate the possible downsides, you will be much more likely to take action. 

To mitigate these, landlords can offer appliances "as-is," charge a fee, or allow tenants to bring their own.Good Luck!

There's also a wind mitigation inspection that they also require if you're getting windstorm coverage.

Are risks really mitigated with a seller giving you a re-purchase agreement or a hold harmless agreement?

If your other tenants find out about it, they may feel unsafe and decide to leave and you would have to let them based on current law.As with all renters, you have to identify your risk and then mitigate it.
