I've consistently written about the forces of nature and her current and future effects on the real estate market (even while often being ridiculed and politicized on this very site for it) regardless: I personally moved and invested in coastal Oregon in 2018 from Venice Beach Los Angeles partly as a result of the trajectory of climate and have assisted several clients that specifically purchased on the Oregon Coast for their own 'climate havens,' investment and future retirement homes. 

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? 

I don't know NY law, but in AZ, you may send two certified letters. 

Meaning if one partner initially contributes 60% & the other contributes 40% then that would naturally give you a 60/40 split2.

You will then naturally refine your approach as you get feedback from results.

I would send it certified so they have to sign for it. 

Agree it is difficult to assess costs when they vary so much by location.Keep in mind that some turnovers are sickenly expensive, and that is just the nature of the business. 

Naturally I asked "how do I find a reliable wholesaler?

@Arron Paulino Your posts illustrate the challenges of exiting SFH's in markets where the natural buyer is another investor and not home owner.

It is naturally insulated and it captures passive heat with strategically placed windows.
