If they outright refuse, or if they fail to meet my deadline, then I would file a complaint with the commission.

What form is that again and what happens if you missed the March 15th deadline? 

Another question: can one do a 2023 cost segregation study in 2024, but before the April 15 tax deadline?

If you don't set internal deadlines and goals, before you know it, years will pass by and you will still have these vacant lots that are not producing cash flow or building your networth to the way you dreamed of.

I ordered well before the deadline to have the Planner included, but I haven't received the planner yet.   

We are nearing our deadline for our inspection contingency and are feeling uneasy about potential rehab costs.

Outlining your SOW with timeframes right out of the gate is imperative or deadlines will be missed yet contractors still want to be paid yesterday!

And then refinancing it in our name to buy it from him and we could add the caveat that we can continue the master lease until interest rates hit a certain point or a deadline is met which ever comes first.

Work on your investment goals - what you want to accomplish, when is your deadline for accomplishing this, how much time/effort/money you're willing to dedicate to this, etc.2.

However I would say this tax payment deadline is the prompt to pay.
