Its a good thing they profited, because projects can go south sometimes and then that really hurts.  

With your boots-on-the-ground approach, you’re in a strong position to find profitable flips.

I ended up making a profit that paid for my wedding and honeymoon!

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? 

Consider offering equity partnerships, debt financing with profit sharing, or preferred equity, where investors get a fixed return before you share profits.

Quote from @Devin James: In one of our development projects, the City staff asked us to remove 40 units from our concept plan.This wasn’t requested by the City Commission at a formal hearing, it was the opinion of the staff.Our original concept already proposed fewer units than the current zoning would have allowed.Here’s what erasing 40 units means:- 40 fewer homes for buyers- Over $1M in lost profit for our team- Fewer tax dollars and impact fees that could’ve benefited the City’s infrastructure & servicesWe gotta get betterEveryone wants more affordable housing, but not everyone wants to do what it takes to achieve it we never listen to the recommending bodies. we move for city approvals and work closely. the other thing we do is keep going back to the same groups over and over and over and over every month on the same agenda and make very small reductions like 2% or 4% and that reduces and beats them down eventually they accept what you want. it's just before beating a dead horse. we keep tabling until they give us something we all agree on then we go to vote. in our city in columbus we have to get recommendations but that's our strategy. we used to come out as aggressive as possible. we typically study developments in the area and keep it very similar in terms of density. we have a track record of very controversial projects and litigation and not taking no as an answer. after a year of that haha I can tell you it's not worth it. now we are more relationship based and buying the right kinds of plots of land. if the numbers don't work on the front end don't do the development. 

By prioritizing five-star reviews, I built a strong reputation, which led to increased bookings and higher profitability.

Generally larger commercial properties and shopping centers are easier to classify with hard and fast rules, but to the points above the residential areas really move very quickly and have way more nuance than most people care to admit.zip codes are generally way too large for my liking at least in my market to provide any kind of insights other than macro level economics but even then highways or rivers that cut through a zip code can end up with totally different trade areas.we can get pretty granular with cellphone data and with grocery center data to understand the trade areas and their true boundaries, but that kind of data pull is generally only cost effective for investors doing larger scale projects or developments, and honestly we still just end up getting on the ground and feeling it out, so I generally tell people that the money is better spent on a plane ticket and weekend trip in the area you are looking rather than any kind of "trade area" level data studies.and generally B class in 1 area means something different than another. 

However, have you considered partnering with someone a little larger in scale for a deal or two?

Hey @Brett Baker, generally, any place with a great water view or directly on the water will bring more revenue.Of course profitability will all be based on purchase price and prevailing nightly rates in the area.If you find a cool 2/2 or 3/2 right on the water with a great view for 1.5m or a 2/2 or 3/2 house a block away for 600k, then I would look at the house over the condo.
