We also send an automated invoice using QuickBooks every month.  

The HOA requires owners to send in invoices of fireplace inspection every other year, 2022 was that year.

I modified the standard invoice the read "Rent Due" and email rental invoices to tenant. 

Can you imagine being the PM who pays a vendor and sends the landlord all the rent while they refuse to pay an invoice?

@Robert AlexisSearch permitsAsk for contract list that performed major work, ideally with scope of work and paid invoices behind it.Search liens and lien releases While there are a lot of flippers that do fine work without pulling permits, it would give me pause if they didn't.  

I attached the photo of 2 invoices they sent me and my wife paid them already

After inspection, the invoice came at $560, same vendor. 

Be sure you understand the full process if you sign up for one of the utils "convenient" options.As a PM, daily I review, approve, and initial every invoice that comes through the front door, every month, before passing them to accounting for payment from the Owners funds.

Enter a maintenance request, assign a vendor, attach a fake invoice.

So if I invoice my friend for the work and he can write that off to prove less profit, combined will we pay less taxes?
