In that case, a run around would be good, have a look at ford transit connects, solid engines , and can be picked up for cheap. You’ll have to obviously expect a high mileage van, with a fair share of wear and tear.
If it lasts you a year, and you are able to move, then you could look to finance a better van.
Alternatively, stick with what you’ve got, and work hard to move as soon as possible, or aim to get a round of, say, £1500 a month coming in before moving and upgrading to a van...
