Couldn't make the title long enough for my actual question, which is where do you draw the line at how much money you sink into one of your own builds? Before anyone says building your own projects to flip is a losing proposition, I completely agree. I'm working on getting a hot rod shop started up, but need to get some builds under my belt before I start hawking my skills. And, ideally I'll first apprentice for someone else for a while, but for the sake of argument, let's assume that I don't. I got a '54 F-100 from my boss, and actually got a really good deal on it, but it still needs probably $3000-4000 in parts put into it. I can probably pare that down some once I find out whether it needs a whole floor or just some small patches, but it still needs all of the glass, a new wiring harness, etc. I'm also setting aside ~$1000 for tires and wheels so it doesn't look like something that was just thrown together when I go to sell it. My concern is knowing how much these trucks are going for, which I can't put a finger on. I can't afford to paint it after buying parts, so as much as I hate to, I'll have to dress up the frame, under the hood, and as much of the interior as I can while leaving the truck unpainted. All I have to go by are eBay finished auctions, and they're all over the place. Anywhere from $5000-$10,000 or sometimes more. Obviously, the more money I can get out of it, the better since it's going back into tools, but I just want to make sure I don't really overshoot the value and get $5000 out of a truck I have $7000 in, not counting labor. So, how do you guys plan out the cost and return of your projects? If I didn't need the experience, the best course of action would be to try and get it running in its stock form (I'm putting a Cadillac 500 in it) and resell it, but I need the experience more than a few hundred dollars I would make off of flipping it.
