I have a signed contract detailing scope of work and completion deadline.

Give them a deadline to complete the project or cut your losses and find someone else that can complete the project ASAP.Lots of hard choices, but that comes with being an actual investor and not all the rainbows & unicorns that many on this site promote.

But since you were past the deadline for protesting they should give you the valuation that you purchased the property.  

Tax season is in full swing, and for most individual taxpayers, the looming deadline for filing and payment is Monday, April 18, 2022.

It's time to get it back.Any time I need something from a tenant, I set a deadline for their response and a consequence/penalty if they fail to comply.

You should work with an agent to get the paperwork square and make sure you don’t miss any important deadlines, but you can definitely make an offer prior to the prelim and walkthrough, and leave during the inspection period without risk if you see anything you don’t like.If I were you, I’d offer 60% ARV, which is likely close to FMV in as-is condition ($180k).

From a 1031 standpoint, faster closing simply means faster exchange deadlines.  

This is roughly the message I send to my tenant 60 days before lease renewal:Dear tenant, Insert nice words....Your lease is expiring on [date]You have the following options:Renew your lease for 12 month at [rate] (If market rate is $100 higher I tend to increase something, if market rate is $200 higher I use (current rate + market rate)/2 for the new rate, if market rate is same or lower I would keep it the same rate)Move to a month-to-month lease at [rate x 1.25]Vacate from the premise on or before [lease end date]Please let me know by [deadline].

Doing ground-up construction, where you buy land find the builder, and get a construction loan would be very difficult due to the deadlines of the 1031. 

This profession can be tough, especially when starting out for reasons mentioned above, but it is also extremely rewarding, fun, and allows you the freedom to live life the way that you want to live it rather than sitting in a cubicle being yelled at by 4 different bosses about a deadline.
