Very new to fruit tree scene and need some advice

[Martin H]

I think in your position, Player, I'd plant the two trees and see how they get on. Unless you are truly in the middle of nowhere, there's probably a pollinator partner hidden away within bee-flying distance. If in due course the trees seem to be struggling to set fruit, find a spot somewhere in the garden for a nice decorative crab apple tree.

Good luck!

As others have said: there could be other apple trees nearby to pollinate yours. If there aren't, maybe it's because they don't do well in your area.

In the early years trees often don't crop well. Hard pruning is often required to shape them properly and that reduces flower bud formation as well as removes flower buds.
A tree trying to grow rapidly and fruit at the same time often suffers from bitter pit.
And young trees often don't have enough flowers to make it worthwhile for bees to visit; the energy/nutrients expended by the bee flying to your tree is less than what the bee can harvest from the handful of flowers on a young tree (and probably really annoying for a bee to have flown miles only to find another bee got there first and harvested everything useful!).

It would be possible to graft a branch of one or both trees with a suitable pollinator variety, similar to a family tree but just a small part of the tree is the pollinator rather than half-and-half or thirds as with family trees.
Also a dwarf bush or cordon could be the pollinator and doesn't take up much space.
