I type the equation right there on the invoice so it is completely clear what is being paid for.IF the unit isn't already rented, you now change the date that the apartment is available in your listings, and do what you can to "mitigate the loss" by trying to get someone in asap. 

I'm talking about buying at 75% ARV for cash and then, once it is rented, getting a 75% ARV loan to, as Alex advises, include an invoice for prepaid rehab costs and, there was something else but I can't recall it, it may have been closing costs, so that the loan will repay me all the cash I laid out to do the deal. 

In order to recover the full replace cost value (RCV) you will likely need to have your contractor provide an invoice for the full amount of the claim or show receipts from materials/labor totaling up to the insurance claim amount.

You should try to get copies from seller broker of all the invoices of utilities and contracted services like garbage, maintenance etc. and also search city fire, police, building and the health inspection records, (they are public records), of their siting any concerns for the building.

Can anyone recommend a service that will automatically send out invoices to tenants each month?

IRS auditors will want to see both a check and invoice/receipt or credit card and receipt.
