I do three regular jobs for a small management company.
1) A block of six two storey small flats I put up from £50 to £60 after 5 years
2)A semi from £20 to £25 after 4 years
3)An old 4 storey house divided into 4 flats after 5 years from £45 to £60
1) is an easy one hour job 2) is about 25 minutes and 3) is about an hour but can be an hour and twenty when parking is difficult and I have even driven back at a different time or used a backpack as I might be too far from the back to run a 100m hose.
Now the management company has to get approval from the tenants and it's Number One that has said they are going to get other quotes - not the semi or difficult one I really put the price up on!
If they change then I shall drop the lot because in my mind number 1 is what makes me believe 3 to be worth the bother.
