It`s a huge risk, not a discouragement, just something to keep at the front of your mind. If you`re supporting yourself/family/etc and of course need a guaranteed income, you`re going to need a much bigger initial investment portfolio to begin with. When you do this part time on the side as perhaps supplemental income, you`re basically risking extra money, when you attempt to do this or anything similar for a living, you`re risking your livelihood. It shouldn`t be taken lightly, not saying anyone is, just saying though. Very rough estimate (very rough, really), but if you want to bring home $60k in a year in profit as income, you`re going to need to sell in the ballpark of at least $200-250k in sales. Your numbers of $80k are not realistic if you`re referring to sales. Remember, you have an initial investment of (X # of $) that must be recouped as part of the sales. Then you have selling fees (round up to 14-15% for Ebay and Paypal for example). People overlook this, it`s a common mistake, but a very dangerous one to make all the same. If you buy $50k worth of sets and sell them on Ebay for $100k. On paper, you might say you have doubled your money. Not so fast. Here is what it would actually look something like: $100k sold - 15% ($15,000) in fees = $85,000. $85,000 - 20% (for example) in taxes ($17,000) = $68,000 There, you`ve got $68,000. Oh wait, not so fast, remember you put in $50k to buy those sets, so we must recoup the initial investment. $68k - $50k = $18k You`re left with $18,000 cleared after an initial input of $50k. The general number tossed around here on BP and in this thread already is that 30% return is realistic. I agree, it absolutely is. You can see that right here, little bit more, but the above doesn`t take into account packing material or anything like that, so 30% is pretty close. Sure, you doubled your money in gross sales with 50K invested, but you have fees and taxes to account for. Not to mention any packing materials, tape, labels, printer paper, boxes, etc, etc. Very rough analysis but you see the issue. If you want $60k cleared after fees, taxes, etc, you`re looking at 250K a year in gross sales at a minimum, actually $350-400k or more, because you are not going to sell 100% of your initial investment. It doesn`t happen, sets will sit and sit at times and not sell, others will move very fast, you have to account for this. And that assumes you make 100% (double) off of your initial investment (which would be $125k) using the above analysis. It`s by no means complete, there are other factors to consider, and you could do it with less investment and a higher ROI instead, but if you want to quite or day job and be successful you`ve got to take a very long hard look at the numbers. Read what is written here and on the site, plenty of discussion around this topic of going solo/full time. You can be very successful, but it`s not easy, and you have to be very careful, otherwise a slight oversight could end up costing you quite a lot.
