We sold when we decided to invest in our DDs education and when we were on the eve of TTC more children (I wanted to be a SAHM). That was 7 years ago. We had our townhouses for 3 years and made quite a bit. We put the money in shares (and didn't sell during the GFC) and have made quite a bit there too.... but it's so much more liquid than a house. DH and I have realised that we need to move interstate now so may buy again closer to family (in the country) where homes are cheaper anyhow (and so are school fees!). We sold for mobility and to invest in other priorites. No regrets. I can't advise what you should do. Maybe draw up a Pros and Cons list.
