Unless you have tied the hands of the PM, they should produce monthly financial reports that include copies of all paid invoices; current Rent Roll; Delinquency Report; along with General Ledger and other financial reports that may have been agreed to.

Save all receipts and invoices.

One tenant needed to be evicted soon after my husband died and the company charged me 3x on their invoice for the eviction.

If your PM doesn't perform in-house maintenance then you should be able to see the invoice a 3rd-party vendor sends to them when any work is done. 

Please require lien releases from vendors of sub provided materials, If they can't provide money to pay vendors then joint check them or ask for invoices and break up the payment labor/materials.

A few days ago, aside from the receipts of $2000 that I was informed, I got one more invoice of $4800 for the redemption, mold prevention, etc.

Account Closed - Are you saying you're going to pay a GC $160k upfront to do some work to your property and when the GC is done and you hit that ARV (hopefully), you'll cash-out refi and use the proceeds to pay him the remainder of his invoice.  

You'll need to show Invoices that the work was completed, I.e.

They even supply GCs 2 invoices -- one for the client (full price) and one for the GC (discounted price which is actually paid). 

Going to recent cleaning job they performed which was $650 , the explanation is , “water removal, pulled the carpet out to remove the padding, laid the carpet back down and added fan to dry out the carpet for few days, streched the carpet back out and sanitized the carpet “ i copy pasted the descrption from invoice .
