I am looking in to a SFR brand new construction that offers live and work usage.

Market is the best remedy for those, since no intelligent buyer/investor will touch what they offer.- Sellers who are lied to and taken advantage ofHow exactly are they lied to and taken advantage of?

Additionally, investing in opportunity zones, often found in these areas, offers great tax benefits.

If you're open to short-term rentals, that could be one option.If you're looking more at long-term renters, you (or your realtor) can negotiate seller credits into the offer and use those credits to buy down your rate.

Complex setups don't offer much protection for most people. 

They were offering wayyy above market 

I am at the beginning of the process my offer was accepted 2 days ago and I just looked at the place today.

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

Excited to learn if this could be a viable direction to explore and grateful for any advice or help anyone can offer for how to get started.

Wholesaling is doable outside the market but you will have a hard time knowing what to offer and selling deals.
