After some research online, I am reading that the cost per square foot on a gut renovation of this nature in Stamford CT is anywhere from $150-$350, which is ultimately not very helpful, because at $150 per sq ft, this is a very appealing project with a total profit of ~$175K (46% ROI) and at $350 per sq ft, it very much isn't, because it would be a net loss of 83K (haha).QUESTIONS:What can I do refine my estimate a bit given that I am not allowed to a formal inspection on the property? 

Sales tax is also very high.

Temps were also very cold the last few months.

Very helpful! 

It's recommended to discuss with an attorney knowledgeable in your state laws to determine the benefit and best structure for your situation. 

@Brittney Yang first red flag is it doesn’t sound like he’s that interested in long term holds but the primary reason for partnership is expertise in renovation and secondary reason is balance sheet and income to help get financing.Regarding reason one, I would offer to compensate him for his time in assisting you and have a very clear scope of what that responsibility is.

outright flips are very, very difficult right now. 

If there are a lot of holes, best to paint the entire wall.
