My parents moved out when I was 17, they went to the Channel Isles and I stayed in their 5 bedroom house alone to finish college.
I then went to a flat which was HORRIBLE I mean, literally, the bedroom STANK of P1ss as it had TWO horse stables under it, I had cold showers for 6 months because the boiler broke and the landlord didn't care. I had a tv, a microwave and a half decent washer/dryer and that was pretty much it. I lived on morrisons 75p value meals BUT it was my place. Girls loved it, I knew no-one either and it was great!
I could walk around in my boxers with not a care in the world. I had clean lovely bedding vacuum packed in the wardrobe for a quick change over before a lady friend came round and a fleet of those lovely scented candles too for romantic lighting
Do it and never look back
