I'm seeking opinions and examples of per-square-foot costs for constructing new multi-family developments in NYC. 

In some places, from what I read in Forbes, even a finished outbuilding might be noted separately rather than rolled into the main house’s footprint.

Because now we eliminated the foot-print of autos.

In regard to the best interest rates, the market is pretty fragmented so it's best to check around wherever you are looking to establish your foot print. 

They have a far reaching footprint.

That's it, but a) print out a page for each property you think is comparable, b) make the list of repairs long and inclusive of everything you've done. c) Put larger items first like kitchen remodel......and don't just say 'kitchen remodel', list things like 'custom backsplash tile/Bosch appliances/recessed can lighting/pot filler/etc. d) Cite the price/value of the work done, and don't be afraid to be generous.

Warranties often have limitations, like they might not cover pre-existing issues, and there could be delays if they require you to use their contractors.I'm not sure if you've purchased a warranty already, but before purchasing a warranty, it’s a good idea to carefully read the fine print to see what’s covered and if there are any exclusions.

To learn more about which one may be best for you, feel free to send me a private message.Old Town North: An Unused Eye Soar Transforming into a 2.5 Million Square Foot Community CenterThe GenOn coal power plant, which opened in 1949 and was shut down in 2012 due to concerns by residents about local pollution, has occupied an unused 20-acre lot in Old Town North for the last 12 years.

The "fine print" here is fairly sizeable upfront fees and high interest rates, relative to a traditional construction loan from a bank.  

Engineer didn't note if there were frost free footings.
