Their units have exceeded expectations over the past two years.Danbury should be fine for house hacking with having a larger number of mulitfamily properties within the city.

We profit about $1200 a month from both units.

Have a strong partnership agreement that clearly defines roles and responsibilities, profit sharing, exist strategy, etc.

We genuinely value architecture, history, design and quality, even if that means minimizing profits.

Any ideas on what I could turn it into to help generate some extra profit?

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

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. 

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? 

Correct me where I am wrong with my perception and walk me through the benefits of going with a turnkey company, where the profit is for the investor, and if the benefits outweigh the costs.  

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