I'd take the duplex comps and use every bit of Like Like Like I could (like location, like specs, like age). 

I can’t speak to the numbers since I have not seen complete plans and specs and finishes level of construction site conditions etc. but overall they look average for a typical straightforward project with vinyl siding or fiber cement siding shingle roof mid grade level of finish.  

Unfortunately they don't have their own specs for escapes so they're just deferring the engineers. 

I have been out of the Real Estate Market for quite a few years, some of my history1980s - Framing Contractor1990s - Small Residential Spec Builder2000s - Left the Construction Industry for the Tech Industry (Missed both the RE Boom and the Bust)2015 - Looking to get back into Real Estate "Buy and Hold" or "Build and Hold" for retirement.I am anxious to dip my toes back in the market, have some concern about the local market.

Over the years I've purchased more residential rentals, some commercial properties, and done several new construction, spec homes.Remember it might not all happen at once, but if you keep making small steps forward, you will be successful in real estate.

The only way you could convince me to that is if you had developed a full set of engineered plans, a spec book, and a detailed bid package that included exactly what my scope of work is.
