Hi Lisa,
how's it going.
Just a massive piece of advice!! For gods sake go and see it then give them a price, I never quote over the phone because each property is diffrent!!
Don't price by the hour cause you could get stung, for instance if you say 12 hours and you have completed it in 9 then the client is going to expect a charge for nine hours!!!
I have done a one bed flat. which had to be ready for re-let it took 12 hours, which included pulling out fride freezer cleaning everything in site, windows, frames, cupboards, etc.
Properties going out for re-let are required to look if no one lived in them,, if the client wants a good thorugh job then they are going to have to pay for the ma hoursto do it thoruoghly.
Hope this helps,
but of course peole have different opinions!!
