I finally sold my Advanced Healthcare card. It took about a month for the card to move off the market but it finally got sold.
It isn't the most expensive technology card at the top of the chain mostly because it isn't very useful. So now that it has finally been sold, I am looking to deploy that capital a bit more effectively.
After reading this fantastic piece about which building bring the best value for your buck to increase your population, I'm looking for more basic homes:

I bought 5 for a start now, but I'll probably buy more in the days to come to increase the population. The population bonus has been decreased over the seasons and now, you will need something more to get all your buildings working or they will be inactive.
