I don't know if your mango is a small growing type but mangoes can grow into large trees if they get the right conditions. So I would reccomend planting away from any buildings and try to prune into a suitable shape for ease of harvesting. Just an observation but smaller trees seem to have more fruit on them and they are much easier to pick. Be careful of the sap from mango stems as it can irritate the skin and eyes.

Good luck.

looks like it would grow into a nice tree shape as is. maybe prune off the lower branches and only have the top 4 branch out.

You'd be better off to prune out the centre of the tree and let the side branches grow out. Fungus is a big problem with mangoes in humidity. Opening the centre out lets the sun in and good air movement.

If it's a grafted tree it won't tend to grow so tall, the grafting stunts them. Tall growing trees usually have smaller fruit. And it's easier to pick fruit from a smaller tree. Mangoes also like some extra calcium.
