Welcome aboard lando,
Most of us had similar circumstances. No time, money, room.
You can learn a lot from this site, just jump in. Join a group build. It forces you to build something and gives you another reason to, plus you learn tons of stuff watching others work and reading the advice of more experienced modelers.
Don't be afraid to ask. The folks here are supportive and positive and more than willing to share their knowledge if you ask.
