Reading through the comments some of them appear genuine, others... not so much. Which is really more befitting a facebook group than a technical automotive forum IMO.
My back is against a wall and a friend of mine threw me a lifeline by offering to show me the finer points of something he's been successful at. I have covered under a carport in my backyard about $40,000 worth of pristine restored Mercedes W126 (actually worth maybe 10k on a good day) that took four years and change to get to that point. So I get how expensive and all consuming restoring a car can be. At the same time, I've seen someone do it for a profit consistently over the past couple of years. And I look back on my experience with my 126 and think had I not been living in an apartment and could have done X,Y,Z myself or had I not insisted on sheepskin flooring or putting MLV in every conceivable place or high end speakers or having the best guy in the country redo my wood veneer... realistically I probably could have done it for a hell of a lot less.
I've looked at this from a variety of angles and both feel its viable and worth gambling what's ultimately only a few thousand dollars. I would be just as unemployed if I wasn't doing this, at least this way I'm having fun and am occupied. I do appreciate the concern from those who expressed it genuinely but the bandwagoning is not particularly helpful.
You seem dead set, which is good. That means you won't quit half way through. You'll also have to learn things the hard way. Welcome to the club... I'll be blunt.
If you came here looking for someone to blow smoke up your backside, you came to the wrong place. Most of the older users here are entering five or six decades of life, maybe more and they have seen a boatload of new faces come here, ask lots of flipper questions and seen many of them burn into the ground. I've seen several guys come in here thinking they could get rich quick, do a quick wash and rub then double their money to some unsuspecting buyer. Few of them make it. Most of them get known as thieves and scammers. You still see their stuff sell, but you also hear about the lawsuits. Some are decent people and try hard to make a go of the cruiser selling game and you watch them suffer, then see them sell off everything when they get a divorce. That's the reason you see advice that tells you to take a breath and look before you leap. Especially when you come across as desperate and unemployed. If you take it as a personal insult, then that is your problem. Not the fault of the people trying to make sure you know what you are getting into before you make a leap into an all uphill fight.
Now, about your original question. That cruiser you put up is a pile of crap. It better be dirt a$$ cheap, because that thing is going to eat you alive once you start digging into it and the kind of people who have $25k in their bank account are going to want to see one that has "At Most" one crash. Not five. In this market, you might win the lottery and get your coin, but you are rolling the dice hard and hoping for a dummy with more money than good sense to come along. Yes, they are out there, but do you want to be the one telling a Judge that "Buyer Beware" applies to your sale?
You wanna make a $20-25k rig, you start with an $8-12K one that has surface rust only, from the desert and you replace every rotten piece of plastic on it with the ones you stole from a rust bucket pile like the one you put up and fix the drive train leaks. Then you do your magic and market it to the right place. Who knows you might get paid stupid money for it from someone who is desperate to be cool.
You want to sell one for $12-15K, you buy that one, do a great job of fixing it, make every single mechanical piece on it work the right way and spend 3 months doing body work, then sell it to someone who has that kind of coin laying around and is willing to accept it for what it is. A rehabbed rig that has hidden rust bombs waiting to go off in a few years.
Good luck. If you never come back, then so be it.
