Never had a pet, looking to adopt American foxhound

For starters, I’m a young adult who’s never owned any pet besides maybe a goldfish 20 years ago.

I’ve purchased a townhome with a smallish backyard, I work from home and have no kids and plenty of time and attention to give.

I’ve been looking on pet finder and have fallen in love with a 3 year old American foxhound in need of a home. Any advice before I fully go through with it? I want to ensure my home is the best for her before I inquire.
