You have a bit of time yet so wait and see how you feel when you are nearing the end of your NPPL.
I went through the same route as you to get my PPL.
The issues you are likely to come up against are various:-
1. Insurance will be an issue with a newly minted PPL.
2. If you are intending to run a LAA type I recommend you join a group rather than set up on your own. The group is likely to have a 100 Hr requirement for the insurance but it's often possible for you to pay the increase in premium until you have the hours. When you are training you are in an organisation with a bit of structure. They will decide whether the conditions are OK for you and will also look after the airworthiness of the aircraft. If you are in a group you will have the advantage of other group members who know the aircraft and who you can ask for advice. Out on your own with not a lot of experience it will be very easy to sucker yourself into a dangerous situation. That's not a reflection on you, it's just human nature and we all do it.
To give you an example, our group has 4 members operating a Luscombe 8E. It's on an outdoor tie-down, which is OK because it's all metal and we do the bulk of the maintenance work. We each pay around 55 quid a month and 35 quid an hour wet. My share cost me 4k.
Good luck!
