I submitted a bid to paint the customers home.$10,000.00 labor.

Documentation must be provided to prove the change in occupancy status​.Non-Occupant Co-Borrowers: A borrower who is a non-occupant co-borrower on another FHA loan may still be eligible for an FHA loan on a property they intend to occupy as their primary residence​.If you want to rent out your current home and you need the rent to offset your current mortgage payment to qualify for the new loan, you run into another set of FHA rules. 

If possible I'd even request it be documented on the invoice.

A Borrower with an existing FHA-insured Mortgage on their own Principal Residence may qualify as a non-occupying co-Borrower on other FHA-insured Mortgages.Rental Income from other real estate holdings may be considered Effective Income if the documentation requirements listed below are met.

Make sure to have clear documentation of regular, on time rent payments and the agreement clearly laid out.

Unfortunately this is not as apparent and may require speaking with past borrowers but I would go with the lender with a streamlined and rationale draw process even if the underwriting/ origination process requires more of my time & completing/ turning over additional documentation.
