I'm also confused because I'm going to be charging them to live there, so how exactly do I invoice them in a way that isn't going to hurt their ability to apply for a mortgage in a few months?

One bank account is best just make sure that you put a class for each transaction you pay for and make invoices each month for the rent income designating a class. 

Are all my invoices uploaded to my owner portal?

I would send them the invoice.

@Jon Klaus  I just made a clarifying post.however its regional in my mind.. in the PDX market we are flat fee based.. from as low as 7k if your doing volume 20 to 30 homes a year in production housing.. to 25k or more if you building customs.I average on my 350 to 450k builds 12 to 15k flat fee.. all other subs at cost ... and for insurance purposes we can't pay the subs direct we want that insurance on the GC.. but we are a signer on the GC account that is opened just for that build job.. our draws come into our account then we transfer the funds to the GC account.. and the GC pays subs.. but we get to see each and every invoice and check that goes out...

Have it taken away and send invoice of drum and pics to code guy. 

The current owner just put about $4k into repairing/replacing parts of the roof (I have invoice and receipts in hand), but the inspector noted this about it after taking pics, showing other damage:  "Damage, deterioration, staining, moss type growth, improper installation, and repaired areas were found at the roof coverings.

The reconciliation should be very accurate as the lease should also allow for the tenant the right to audit landlord's records including seeing copies of actual invoices paid.  

They don't have a phone number and the address listed in the invoice is a residential address ( I called the tax assessor office to get this information ).
