pfft cheeky cow!!
that is not right one bit! i don't rent a chair myself but my friends do on a 50/50 basis and the same 10% to the owner on colours/perms, BUT i am a previous salon owner and when i sold the salon i was selling the custom as well as fixtures and fittings, but mainly the custom,..... sounds like she is in money trouble and just wants to stay doing the same but not having the hassle of books to keep and bills to pay!
after all if you buy the stock as well you'll end up making like 3% profit a week???? she is trying to take you for a serious ride,
IF you still decide to buy this business you need the contract to say she MUST Leave the custom, it is with the shop!!!!
i sold mine for 20k and 13k was custom and 7k fixtures and fittings,
if she is retiring let her retire! she may sell to you then take all the custom and run to do mobile!! don't be caught out, and as for your training get that done while you work, and get other staff in or do the chair rent thing with other staff,, on your terms, after all it will be your business
hope this helps xx
