I'd stay away from Raleigh choppers, they're just a joke on many levels.
Frame construction is really poor, spot welds for the most part, but whats worst is actually riding one.
For starters you look really daft, its of a different time, but it's real inherent problem(riding) is the small front wheel and large handlebars coupled with zero reach stem. Controlling that is hard enough.
Selling on is hit or miss, and although some other mug might buy it, the vast majority isnt going to be looking to pay thousands or even hundreds, and its pricing is akin to a dutch tulip market.
Currently bikes in general, as in retro bikes arent a good market, and to renovate such is again dutch tulip market pricing, you can pay too much for what is total tat, and you'll never see that outlay back again.
Trust me, this is my subject. I've been absorbed on bikes, especially 'retrobikes' since 2008, and have watched it grow and then crash, because too many are asking too much for tat, and that tat isnt selling to anyone you has even an inkling of the market. I luckily got out of it, selling my early Hope technology collection(probably at the time the biggest in the UK, outside of Hope's own museum) about the middle of last year, when it seemed there was a bit more money floating about. Currently theres less expendable income in peoples pockets, so they are looking for a lot for the parts you'd need to rebuild bike,motorbike or old car. Those are the subjects I'd avoid, and stick to something you can barter later on as a skill.
I'd suggest finding something that teaches you another skill. Welding, metal working, even paining in oil or watercolour, but projects, have increased too much in outlay and its too fickle to expect to recoup that outlay.
