Avocado can make a good houseplant, but will soon get too big. Grow it
for a year or two but unless you have a conservatory it will soon
outgrow its space. If you want to get one to fruit move to somewhere
like Barbados!

Friends of mine have had an avocado for some years. It got too tall, so
they cut it back a few years a go, and it continues to grow happily
