There was a mistake on the rental income reported so I had to fix that and file an Amendment. 

Always get everything in writing and stay on top of scope creep (amend the contracts).

Seasoned attorneys may not always be up to date with new or amended law while young attorneys may not have enough experience.

A recent small structural amendment took over a month.Our existing area downstairs was already finished as part of the main house.

Moving shares between members does not require amending the operating agreement.It's worth talking to an attorney to get the structure set up correctly so you don't encounter this, or other unforeseen snags in the future. 

You are also able to retroactively claim this deduction if you file an amended tax return.As a taxpayer, how do I report this deduction?

So the buyer's 3rd attempt at making the assignee borrower (LLC) look like it wasn't a disregarded entity was to amend the Articles to essentially say "we won't treat it as a disregarded entity anymore". 

Once approved, they sign the lease and become responsible for the full terms therein.I personally charge a $50 fee every time I have to amend the lease, which means $50 for each tenant being added.I'll bet dollars to donuts this doesn't end well.

Also, I amend countless returns annually by CPA's who don't know real estate. 

Since you are already under contract on the property, I would consider sending an amendment that you as the buyer will be changing your financing terms from conventional to FHA.
