Finances are finances and everybody's situation is different. Some will agree, some will agree to disagree and others will down right disagree.
Seeing how you figured that 25% of what you would borrow would be ate up in fees, don't borrow against your home. This would lead me to believe have only been in your home a short time or are considering a lending company, not a financial institution like a local bank.
The only way I would recommend borrowing against your home is if you have been there 7-8, maybe 10 years and have equitity built into the home. Also if this is going to be your last home, not something you're trying to flip or only live in 5-6 years. Interest rates are still low but going up.
If you're considering borrowing against your home, also take into consideration the loan interest if you itemize on your income taxes. This may work for some but not for others. I know there are some members that have borrowed against their home to buy a new vehicle, lower interest rate plus a tax deduction. Like I said, everybody's circumstances are different, it may work for them but not for you.
Credit cards. Again, what works for some may not work for others. As long as you are responsible with credit cards, there is nothing wrong with them. BUT YOU HAVE TO BE RESPONSIBLE. You
might also find that having one or two and using it occasionally (responsibly) may make your credit rating better, the better the rating, the lower interest rate you can get in the future.
Lowe's, Menard's and HD generally offer a 6 month interest free program on charges of $300 or more. I have used this many times working on the house and garage projects. I consider it (you'll hear businessman talk about this) using other people's money. As long as you pay it off in the required period, it costs you nothing. Again, you have to be responsible.
Contractor financing? Signature loans? Polish Quido "the shark"s limo for 20 years?
No, no, and absolutely NO. Enough said on this methods, the same goes for check advance or payday advance places. . . NO.
If you have a hard time saving the money, consider having it removed before you can spend it. How ? Increase what Uncle Sam takes out of your check, you'll get it back at the end of the year, if you do your taxes properly. Granted, you will not make interest on it but you won't be spending it either.
There is nothing wrong with building your garage in steps or as you can afford it. If you can get it closed in as a shell, it'll make life easier to if you have the skills to do the rest yourself. No skills or need to learn, turn on HGTV, buy a few books, help a friend/family that is doing some remodel work. Sweat equitity, is about the best return on your investment, about the only thing that comes close IMHO, is insulation.
Not that I've said that, you'll see some that agree with it, disagree with it or consider it completely wrong.
