Going along those lines, I hope you always mailed everything to the HOA via confirmation signature required or emails were saved in your sent file and everyone cc'd. 

Thank you that is great advice, I have started a spreadsheet with the BP calculators to design a streamlined analysis process

There is usually a size of lot per unit designation.  

Antifa now these days  LOL3. commute is a big one in many markets. 4. new versus old  IE old 70 year old homes with limited functionality compared to brand new homes or newer homes with modern designs.

With not having confirmation on certified mail being delivered, how would we move forward with pay or quit notices or eviction notices?

I'd recommend that you chat with a mortgage broker for confirmation and make sure that your income (with a commission component) has been properly recognized.

There are brokerages that are specifically designed for just this situation.
