I told him it is single member and I selected disregarded entity when applying for EIN.

Then I had a few groups (without permission became much larger groups)  that had complete disregard of not only my home but the adjoining homes.

@Joe WoodAssuming your business is a sole proprietorship or disregarded entity, @Ashish Acharya is correct that the federal and NJ 2018 tax year Q4 estimated payments are due 01/15/2019.If a C Corp, they were due 12/15/2018.

You also have liars who disregard the law and have no money.

I am not sure if anyone has a suggestion on how to persuade HOA as they completely ignore and disregard all reasonable arguments we brought up, narrowing everything to rules and regulations of association. 

First because it is probably a disregarded entity that doesn't file it's own tax return.   

Now that does not mean I completely disregard the price I’m paying but terms to me make or break a deal more than the price.

Disregarding appreciation.  

Or can I just leave it as is - "disregarded entity" ?

Linda Weygant while we all appreciate people who offer advice, it needs to be accurate, especially when it comes to taxes and liability protection.A single member LLC is disregarded for tax purposes.
