I learned throughout ten years as a data scientist that most of the world doesn’t care about your r-squared value.

Gather data that can help you make an educated decision.

I would see how much data I can get in regards to people searching for electric ports for charging their cars.

@Don Johnson  In general, the East side of SLC usually has the best appreciation for single family homes (neighborhoods like Sugarhouse, the Aves, East Millcreek, and anything along the East bench usually has good appreciation...but they also tend to be expensive properties to buy...).  ...everyone wants to live in those areas, but there's a finite number of houses to go around, and very few new single family homes are being built in those areas, so it's a fairly straightforward issue of low supply and high demand.However, I think I saw a stat recently that showed that some West side areas like Taylorsville had the highest appreciation in SLC last year (even higher than the East side neighborhoods)--my theory is that the East side has become so expensive, that most "normal" buyers (that is, people with fairly typical incomes) cannot afford the East side anymore, and are therefore being pushed toward West side areas like Taylorsville, driving up prices in those areas.... that's just my hunch (I don't have any data to back it up). 

Proof, numbers data evidence..

Propstream.com - A great platform for data and even comes with a national MLS platform which is very useful.Code Violations - This is a free list of all houses that have had a violation in the past month (high grass, boarded up windows, tarps on roof, etc.) you get this data from your local county office.These are just a few of my favorites, best of luck!

Or do they license the data? 

I cannot find data on any MLS services. 

I know on the most recent 19 unit Comed gave us all the data from 2021.But in general, I think if you estimate between $100-$150 per unit per month, which gets you to a similar number @John Warren mentioned.I honestly try to avoid boilers in smaller buildings if possible, just because I always want to add AC and it makes it so much easier if you already have ductwork.
