How do you start an antique store?

Lots of people "know what it's worth" but few know from having sold it. Those selling are usually wanting the most they can get, those buying are usually wanting to pay the least possible. You have to make your profit from the middle... Once you have repeated the above 1000 times, look for an inexpensive location that is easily found. There is usually some location that is undervalued but has foot traffic and parking. I suggest you look for other similar businesses, ones that are Antique stores is best but what I call Destination Businesses are just as good... a business that people will travel to because it provides things that others do not, in my area I have two wonderful clothiers a hobby shop that puts most to shame, great restaurants, a tailor and other such businesses... then pay the rent and work your tail off. Best if you don't have to take any money out for a while... like a year, as it takes time to establish yourself and gain trust in the community. I sold part time for 10 years before I opened and have been open full time 7 years so far. Good luck, it's lots of fun and LOTS of work.
