In 2023 we didn't do that and only showed 1/2 a year of tax payments. 

Your sibling can either take the cash for their 30% or they could do a 1031 of their own.If you and your wife file a married joint tax return then the IRS sees you as the same taxpayer. 

Wonderful taxpayer funded heat map block by block.....  

I looks like the former, based on the following definition --"The term placed in service means the time that property is first placed by the taxpayer in a condition or state of readiness and availability for a specifically assigned function, whether for use in a trade or business, for the production of income, in a tax-exempt activity, or in a personal activity."

The property has since been sold twice and no quiet title action or a quit claim deed from the defaulting tax payer have been recorded.

Can you please elaborate on this:Keep in mind you can use Form 2210 along with your return to show the IRS how much income you earned by quarter and make your estimated tax payments accordingly.

Given the current environment of high prices and high interest rates, it is not likely that a taxpayer will pay tax on rental income for properties purchased now.

However, the real value of those deductions to a particular taxpayer can only be determined in conjunction with their tax professional.

Also, why would State not accept any “contemporaneous record” maintained by the taxpayer (or taxpayer’s CPA)?

You can sell that property as the trust and buy as yourself or as a "disregarded LLC"(an LLC that you are the only member of and that also does not file it's own tax return.In a 1031 exchange, the taxpayer for the old property must be the tax payer for the new property.
