Where should I live? What would you do?

On Saturday I’m going to look at three different houses to move into (renting)... I have currently only seen them online, and am going to see all three in person.

The first is affordable, but in truth I don’t like it.
The second costs more, but affordable… I like it, but it doesn’t have a shower (and I don’t think I can survive with only a bath).
The third is considerably more expensive than the first (by £100) but I am in love with it… It’s “perfect”...

I’m going to be self-employed, but also with a part time job to help make ends meet, and am hoping to build up to a level where I’m not struggling after about a year… BUT as I’m self employed, I’m going to have to use up ALL my savings paying for 6 months rent up-front, so moving again in 6 months or year’s time is not going to be an option.

Help!
