Assuming you have a screwdriver and a wrench, you can pick-up other tools as you need them. This will give you the opportunity to learn to maintain your bike. Perhaps your neighbor will provide guidance when you get stuck. If you break something then the cost of replacement will be minor. If you do decide to upgrade down the road, you will know through experience what to look for, what to avoid, and most likely feel more confident.

Good luck with your acquisition, and your daughters health issues.
Hope this helps.
