I am considering buying a garage for storage space and use as a
workshop for building models. An example of something under £10k
(auction guide price) is he

I have some questions...

....about buying garages:
1. How well do garages keep their value over the years?
2. Will it be difficult to get a landline, plumbing, gas and
electricity in?
3. What is the likelihood of planning permission being granted a few
years down the line to convert a garage into a studio flat?
4. What can go wrong with a garage and how badly can the future sale
price be affected?

....about buying in auctions:
1. Is it worth getting a surveyor to look at the property?
2. Generally, will the guide price be close to the sale price?
3. If planning permission to convert the garage into a dwelling could
be secured, how much will it raise the subsequent auction price by?

Thanks for any advice.
