If you have some space but not a lot, look up "Backyard Orchard Culture".
Practitioners have amazing yields with tiny 5' tall fruit trees. I've seen some people do things that seem crazy like 4 different trees in one planting hole and it works fine.
I have a potted miniature lime tree that spends 8 months of the year outdoors and the NYC winter indoors. It's easy to maintain and every year it produces more limes. This year I got at least 30. They taste unbelievable especially versus store purchased. Highly recommended.
