I want to start buying domains and selling them almost immediately. So two questions, how much could I sell a brand new domain for and do I need to get hosting to sell it or can I sell it without hosting?
You can sell domains without hosting. If you buy a domain then try to resell it tomorrow, Why would it be worth more ? It won't.
Well I wasn't sure if it was worth anything that's why I asked. Is the only way to make it worth more just waiting or how else can I make it worth more?
Some people try to buy dropped domains on auctions, then resell them on a different market. Seems pretty competitive and not that profitable, You could try it for $50-$100 , never know ? but your average $10 domain is still just a ten dollar domain next week
I advise you to stay away from the domain business.Is very competitive and if you don't know what your doing it will drain your budget extra fast.
There is only one scenario in which I would recommend "quick flipping" of domains, and that is if you aready know there is a buyer who has either recently made a legitimate offer or purchased a similar or inferior domain in a particular niche. As was mentioned previously, you still have to know what you're doing, and it's pretty rare when that happens.
