I've done a few jobs for a couple of different letting agents, one is a block of flats which is monthly, this is a good one as all i have to do is invoice them and they pay within 7 days. The other was abit of a bind, probably because i got tied up with the insides aswell. one took an hour to do (inc travel), but i could only charge £25, so it was a bit of a drop for me in rates. The other problem with that was i had to pick keys up and drop them off, hang around in the office waiting for keys- it's all time.
IF most of their work is 15m away, would it be worth trying to pick up some more work in that area? You need to make the travelling pay somehow!
Goodluck with it anyway, and try property management companies as i've said b4!!,i've got so many blocks of flats to do now, i'm at the stage of either dumping the bad stuff (all my work is over £10), or another van, after 3 yrs in the biz, problem is i can't turn work away!! bit like saj! What do u do?!!
