Quote from @Jaycee Greene: Unless you already have a capital reserve fund that will pay for unforeseen, major expenses, like a new water heater, roof, or A/C unit for example, I'd keep the profits in the account until it can cover 6-12 months of operating expenses.

Labor/material are going to be different and need to factor that in4) new roof, new HVAC, new water heater, ac panel, replacing plumbing to PVCThese are very variable, if you are getting this from a licensed guy to do it and unlicensed.. is it a big shop or a local shop doing it, is the GC doing it they will put some money on the top so it will be more money5) framing (creating new bedrooms or baths)I would get all these quoted from a good couple of licensed guys and unlicensed to know your numbers to cents
