Before you get as far as making an offer, you should check for obvious problems. For example, a visual inspection may reveal excessive damp, cracks and so on. You may not want to take on premises in that sort of condition.
You will need to think about how you will use the premises. For example, you should draw up a plan of how you would arrange them. Even if the premises are in perfect structural condition, they may not suit your requirements. Likewise, you may need to investigate whether there is adequate parking and access for deliveries.
You should also make your own informal investigation into the sorts of problems which will not necessarily show up in legal searches and surveys. For example, traffic noise or awkward neighbours. Visit the premises and the area at different times. Ask other local businesses what problems they are aware of.
