Can Someone Check my ARV analysis?

[Tyler Davidson]

Hello, I have calculated an ARV on multifamily I am looking to purchase and was hoping someone could check my numbers. The home in question is 2915 Lynnhurst St, Sarasota, FL, 34239. The ARV I am getting is $373,728 at $229 per sqft. I got this number based on the two duplexes that sold down the street. The multifamily I am looking to purchase would be a total remodel new kitchens, new bathrooms, new floors, fresh paint inside and out, reroof, new ac, brand new landscaping, new fence, and maybe new windows.

2921 Bentley St, Sarasota, Fl 34239 sold for $450,000 ($283 a sqft). This house was remodeled and sold 12-30-10

2941 Bentley St, Sarasota, Fl 34239 sold for $339,000 ($175 a sqft). This house was remodeled and sold on 08-08-18

I was hoping someone could check my calculation and tell me if I am doing it right?
