I woud go cautiously with this one, the property sounds very cheap for premises and two flats. The other thing I would look at is that the flats are sold on long lease, you will need a solicitor to go through this very thoroughly, the ground rent is only £200 per annum will you be liable for repairs, the ground rent wouldt even cover the yearly gas safety checks.
Your legal fees will be steep so you will need cash for searches conveyance etc, why not try and negotiate with the vendor to buy the premises only?
I agree with Chrissie finance is really hard to get, you will need a good reputation with your bank, rules on commercial morts are quite different from domestic, they will also want a bloody good business plan, have you thought about running cake making / decorating classes? this might bump your t/over up a bit, you will also need cash for a refurb / equipment and also probably planning consent change contact your council and ask what permission it has already.
On the other hand my philosophy on life is if you want something badly enough you will find a way to do it. Might be hard but good for you I would go for it.
