This is a battle not worth fighting.

. - Fight the additional bill with the plumbing company that did the damage and then charged the HOA 5K for their "fix", - Argue the HOAs liability ruling that i am responsible for that additional bill that i never authorized. 

@Jason Hudson in this market it is becoming more common for a seller to want to know you are serious and capable before they will share financials and rent roll.

It’s a 4-family house ask for 675K (which my agent says is a bit high so we're fighting that out).

The market is signaling to you to not buy a house, don't fight it.  

The seller is under contract with the wholesaler - who he most likely doesn't know if someone who has no intention of buying the property himself or even capable of it - to then have the deal fall through because the wholesaler can't perform.

They will want to see that you are committed, capable, mesh well, and usually have something in return to provide them.2.

I don't believe this new email account of yours is not capable of receiving incoming emails, but absent any replies, all I have is your personal cell phone number for contact.

Finding a contractor that is capable of doing the work and at the quality we needed was a challenge.

We’ve done several RTU replacements, this is not something a handyman will be capable of handling since the project is HVAC + electrical + plumbing.
