The best arrangement these days seems to be to keep borrowing to an absolute minimum, save save save, buy with savings, and don't fall into the trap of thinking that you have to spend 50K to build a studio to start working. I know people that are very very good with minimal equipment and we've all heard some people's work that's just so-so despite the fact they have every toy in the shed. Start small and get good. Half of 46K is plenty to get up and running, don't let anyone tell you different.
Borrow from family if you have to borrow and set up a repayment plan that gives them just enough to clear inflation and gets you out of debt in less than a decade. Don't mess with banks and business credit lines, this ain't that kind of business anymore.
Word to the wise... do something else at the same time. If you're a computer guy, be a consultant or if you're a carpenter, work part time, whatever. If you want it to be related start a label
or do music licesnsing, children's music... anything to diversify the revenue stream. Be your own financing and forego the divorce and the early grave. The studio is, for me, love and extra income. I'm good with the gear I've got and I'm patient for the gear I want. I've got another job I probably won't leave because it's easy, flxible and pays well. I take off weeks at a time when I get gigs. Not very gear slutty but it works for me.
