Questions Regarding Cash Out Refinance

[Kate Budroe]

I'm finishing up the "Rehab" portion of my first BRRRR duplex property. When starting to think ahead to the "Refinance" step to do a cash out refi to repeat the process, I have a few questions:

1) Does a 12 month lease look better to a lender than a month-to-month for a cash out refi?

2) Is there a minimum time that tenants must rent the property to get the most value out of my refinance?

3) When/how does the appraisal take place in this process?

Thanks in advance!
