On acquiring an aircraft for my own PPL training and later use
Is it possible? Sure. But there are pitfalls you need to be aware of...

First, you may find it difficult to find financing for a new(er) aircraft especially if you are still a student, and especially if you are intending to offer it as a lease-back. 

Then there is insurance, which for a student purchaser is going to be expensive, and even more so if you are leasing back with the idea of it being used in a flight school as a primary trainer. 

The AOPA has a good article on leasebacks:

Lenders Leery of Leasebacks
AIrcraft Owners Guide to Aircraft Leasing
Turning the tables on leasebacks

Along with any number of other articles.

Another thing you need to keep in mind is that when you put an aircraft on leaseback, you, even as the owner, are subject to the same scheduling issues as renters. 

The biggest thing to remember is that buying an aircraft for use in training is not a way to save money, you would be surprised at what it costs to own an aircraft, even on leaseback. You have annuals, maintenance, insurance, etc.
