Any former appraisers? Advice on how to best position 6-unit

[Rishi B.]

Thank you in advance! We're rehabbing a 6-unit in Bridgeport with a built-out attic space; Ahead of starting the refinance in January, I wanted to ensure the two 3rd fl apartments would receive the proper bump in income on the appraisal report for being duplexed-up apartments. 

The questions are mostly around how to configure access/locking doors. We wanted to stay in front of any technicalities that might make the appraiser NOT count the attic spaces as part of the 3rd fl apartments. (The building is a 3 story+attic with apartments in the front and rear of each floor).

Would appreciate any and all opinions - ideally someone with previous experience as an appraiser who could walk the building quickly - I'll be sure to pay it forward! But really anyone who might have any helpful info on this topic. Much appreciated and stay warm everyone!
