Greg's amount is close to what you may charge in my area, $290, but that is pushing the limit of what even the higher end home owners are willing to spend.
Those of you getting $400-500 for a typical cleaning are very fortunate. You may book 2 jobs a month like that here, and because of the cut throat hacks around, your $500 customer will never repeat.
I have actually installed three rooms of new carpet with pad for less than $500 in several of my rentals,( given it was contractor grade carpet purchased from lowes and Ollies remnants.)
I charge $35 per room
$140 5 areas
$20 Stairs, Landing included
$ 65 Sofa
$ 50 Love Seat
$ 35 Chair/Recliner
Spotting issues are charged based upon their difficulty
Protector $20 per area
I try to clean by
IICRC Standards from start to finish, and the job you described would have taken me at least 4 hours, and I figure when all was said and done the bill would have been around $250.
Just like yourself Mike, I paid cash for my TM and all of the goodies that go along with it, but that doesn't mean that it will not figure into your expenses. I am also a new O/O but I have run a number of businesses, and I know how it may seem that you are making money at first, then tax time comes and you owe Uncle Sam more than you made. I suggest that you increase your prices enough to at least be able to bank 40% of each invoice for April.
I wish you tons of luck, Mike
