Third, labor shortages.

If you are being charged $400 they are probably using a licensed plumber with higher rates.From HomeDepot.com - The average cost of toilet installation ranges from $185 to $400 for all labor and materials.

I can share a spreadsheet from what I purchased and the labor charges.

@Joe Funari Thank you for the reply and the advice!

Quote from @Joe S.: Quote from @Clayton Silva: Before people get in my DMs or up in arms about how important interest rates are please take a moment to read in its entirety to understand what I mean.As a mortgage broker and banker, I often hear that a client of mine is "shopping" interest rates. 

Another couple hundred buck in paint and my wife's labor.

@Joe Kern The nightly charge and cleaning fee, as well as any other charges you add, are all lumped into revenue.

As a partner who will be getting a payout at closing day, how much should he be compensated for his labor and should I be compensated for listing the homes?

Pay for labor only per job and cover the material cost yourself.
