Acquire facilities I rejected as investment opportunity (3-2-3)

Ross

I believe the answer is:

buy-to-let

I'm a little stuck... Click here to teach me more about this clue!

'facilities i rejected as investment opportunity' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'acquire' is the wordplay.
I cannot quite understand how this works, but
'acquire' could be 'buy' (buying is a kind of acquiring) and 'buy' is present in the answer.
The remaining letters 'tolet' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
