James, let me chime in with a few thoughts. In a previous life, what I did for a living was operate small businesses, and then consult to other business owners on the profitable operation of their businesses. I did this for almost 20 years.
You need to understand that I have nothing but best wishes for you. To start your own business selling music and gear is totally cool. I would support you all the way.
Howver, you cannot survive in a space with a $26,400 annual rent. Cannot.
If you never pay more than half of your selling price, so you double your money on every sale, you would need to sell $52,800 of records and "stuff" every year to make nothing. To break even. Zero money to live on.
If we assume typical federal, state, self-employment tax (you have to pay your own SS taxes), etc., at a 20% total rate, in order to net $1,000/mo or $12,000/yr, in after tax profit, you need $15,000 in gross profit. If you're doubling your money, you need $30,000 in sales above the break even point to generate $15,000 in gross margin in order to leave you with $12,000 in after tax profit to live on.
We need $52,800 in gross sales to cover the rent, and then another $30,000 above that break even point to give you $1,000/mo to live on.
You need to sell $82,800 of records and stuff every year, almost $7,000/mo., in order to leave $1,000/mo to live on. The chance of this happening is essentially zero.
Sell on eBay and CL. Really. :yes:
