That is the best way to do it, but I can tell you that the closer you get to being done the harder it is to leave the CC's alone, "I just need a couple more things, then ....". I did use a CC for my Major purchases for one good reason though, the protection it offers should something go wrong. Tha trick is to get it paid back off quickly.
I have found from my own, and watching others that if you take most builds and the time they expect to have it done and double it (in some cases triple or more) then you get a more accurate time table of when it will be done. Those little thing eat up SO MUCH time, things never completely go as planned and the cost rising and rising makes a build take longer.
I would come and help you, it would be fun, if I didn't already have so many things on my own plate to finnish up! Spring is a good time to get it out though, you have the whole year to use it and no money left to go anywhere
