You can enter in a legally binding contract from age 18 in the UK. So that's your minimum age to own or rent your own place.
If you are at least 18 years old, you can legally sign a contract.
There may be other rules that apply, however, such as rules agreed upon by a homeowner's association or local council.
There may also be issues with insurance companies, and you may find yourself paying a surcharge due to your age. Since insurance is sold by risk pool, your insurance could be higher, just as it would be on a car.
yeah, so...what is it?
