Just my opinions on this:
60% fail, who says, I've seen figures saying 1 in 3, 50% etc etc there doesn't seem to be an official statistic from what I have seen? I would be very interested in to what constitutes failure...are these people that have sold up? don't forget there has also just been a recession that has taken out businesses who have been around for decades, not just the new ones. With the right planning this figure will no doubt decrease considering there are businesses that start up blind.
In relation to your second point, it might apply to say restaurants that need stupidly expensive cookers etc but for essentially a shop with a big oven, and ancillary foods a fit out could probably be done for less that 20k easily, especially if you lease the equipment to test it for say a year and have a break clause on the premesis.
2 years for what? for who? businesses can start up with no capital, or with 500k capital. Doesn't mean it's going to take 2 years. Providing you do enough research, know your market, price accordingly businesses can break even in months, even less for service businesses like website design / graphic design etc. Again - there are so many variables that this needs to be taken on a business to business basis.
Again - what businesses? even if you buy at 70k, you'll still need to buy stocks, who's to say it will be habitable, not need a load of work that you would then be responsible for, if people are that worried about consents put in an offer with a deposit dependent on obtaining permissions. Hell plenty of businesses start up, operate for a while and put in for change of use when needed. Who says the location will want what the OP is offering? They might have had a cafe there before but unless research is done in the area it doesn't mean jackets would be successful. (of course there are businesses that can succeed regardless of location sometimes if the level of competition is low / non-existant)
To echo one of your points though to the OP - do more research
Absolutely arkybarky I am saying that by taking over an existing business you have a better chance of succeeding?
60% of startup businesses fail within 3 years
It takes two years on average for a startup to become profitable
You can usually buy a business with less than a 2 year payback period
People establising a business invariably underestimate their start up costs and underestimate how long it will take for a business to become profitable. So lets say start up costs of £20k, lack of profits for 2 years 50k, working capital needed to be successful £70k.
You can buy a good solid business in a proven location for £70k and earn from day one.
I suggest you carry out more research on businesses for sale you are overlooking some great businesses.
What I am saying is, if you do not have the money to see out a project then do not start it.
I am a business transfer agent I get a lot of business owners contact me to sell a business that they do not have the money to run and is not profitable. The businesses you talk about that are often overpriced are priced at that figure because the owner needs that money to bail them out of trouble.
My advice look at the risk free option before the risky option.
