Please help me estimate this rehab

[Hai Le]

Hi BP'!! Newbie here. I've been practicing with analyzing properties but don't have any experience in estimating repair costs. Please help me come up with an estimate to fully rehab this place. I know that this should be done via walk-through with a contractor but the purpose for now is to quickly analyze potential deals in front of the computer.  I know there's alot of experienced users here that can help. Thanks in advance!
