David, there are tons of software out there that will serve the functions you're looking for.

If they do, it can bankrupt you.Everyone has a different utility function for risk, so this is always going to be a personal decision...

Our liquor sales for lunch and dinner during the week were minimal, and on a weekend rarely exceeded 3k-5k unless there was a corporate function or special event.

Unfortunately, I've now realized the sheer number of man hours that my desired outputs will require, and am wondering if anyone knows of a site/product/etc. that generates some or all of the following data for a specific neighborhood/area within a city:- Price per square foot as a function of time (average over the past month, 3-month, year, 5-year...) - Average square footage, # bedrooms, # of baths for current property list- Distribution of property types (single family home, apartment, townhouse, condo)- Average age of homes- % or # breakdown of sold properties by month for a calendar year (i.e. for 2016: 12% sold in Jan, 5% in Feb, 20% in Mar...)I know that sites like Zillow and Trulia can provide some trend data, but I'm looking for something a little more specialized.

Function the same way as well.    

I am currently working as an IT Functional Analyst and Statistical Analyst.

I'd look into the possibility of installing heat pumps with electric heating elements for very cold days(one per unit, hopefully, in the units which currently have electric heat) these can be installed in the window much like typical air conditioners and they will function as air conditioners in the summer- some can be installed through the wall.

I then used the IRR function and it came out with a 19% return.  

A good offer is a function of utility, scarcity, business plan, and other things.

$500 here $500 there certainly adds up, but the kitchen is a huge area of focus for buyers, so it'll be worth it vs. a $500 closet system or $500 tile upgrade in the entryway.Also, its my opinion and experience that most buyers (and therefore the market force) don't look at functionality - they look at flash.
