About the garden: Once it is fully established (which will be the case at that age), you only need a few tools and should not be lazy. At that age, everything will be well grown in, so the work is, in my opinion, limited (for example, my parents have such a large garden themselves and do everything themselves without being big garden enthusiasts). You can get tools very well second-hand for the beginning and in general. Or the previous owners might sell some along if they are downsizing.
