It doesn't matter whether it's a conventional bow or a crossbow. There is a broadhead on the front of an arrow which causes interanl hemmoraging if placed in the right area (chest/lungs). There is a broadhead on the front of a crossbow bolt, typically the same kind and which does the same thing as that on an arrow. The results are usually very similar.

The only variable is that it is usually easier to aim and place a bolt into the desired spot, but not always. Just as in gun hunting a deer might not be angled just the way it appears to be, meaning a possible marginal shot placement.

Personally, I'd look for a larger parcel of land to hunt given your experience and your own thoughts on the subject. You also may have to consider state laws on safety zones, meaning how close you're allowed to hunt to occupied buildings.
