Non-disclosure of what could be deemed pertinent data to one's financial decisions is potential grounds for legal issues.

This is all the data your real estate agent can provide.

Hi Liam, curious what the source (website) of your data is.

Check out the sales data on when it was last sold and if it was recent within the last 12-24 months be careful you are not buying something that may be maxed out in current market value.Only way to remedy that solution is to buy and add sqft like extra bed and bath or larger GLA but room counts can be best.

Data mining? 

You need a reason and data to support your position that your property is worth more.

At my brokerage we are innovation with AI chatbot, data portals and integration of technology to add value to the way people search and sell homes.

So I was playing around the data and created a simple interactive map for housing market data visualization by counties across the US, like home prices distribution, mean days on market, listings number, etc. 

I'm learning to be very data driven and have been doing my research/market analysis trying to narrow down where I want to invest.

I will say, when looking, use as much useful data as you can, but more importantly, work with people who know how to interpret the data.
