Recommendations when financing with a Freddie Mac Small Balance?

[Sean Morrisey]

I am in the process of trying to refinance a 16 unit multifamily building purchase in 03/2018 for $875K and believe it should appraise out for $1.4M given an increase in rents and decrease in expenses over the past 18 months.

Freddie Mac Small Balance Loan appears to be the best product to perform a cash-out refinance, but, wondering if anyone has recommendations (based upon experience) of what to ask a lender or due diligence to perform prior to the refinance to make sure things go smooth with underwriting?

Thanks to all!
