I like your dataset and idea to predict real estate value. The idea and analysis are clear in the report. The graph is really cool to see the relationship between different variables.
There are some suggestions to make it better.
From the graph, I only found only BldgArea is related to the AccessLot. So from your linear regression, we can find the coefficients of other independent variables are quite small, only coefficient of BldgArea is higher than 1. You may need to consider other new variables that have power to predict.
I suggest you can search some papers or other research to find if there are other good variables. You can also try to merge other dataset to make your prediction better.
