Can you talk to the homeowner? Will someone be living in the house during the rehab? That will impact your demo work.
If someone is living in the house you better get at least twice the money you would if it was empty because it's going to take at least twice as long.
First thing I look at on a house remodel is location. Can I park close to the house to unload tools and materials? Is it a bad neighborhood where if I leave any materials on the job they probably won't be there in the morning.
Even if no one is living in the house make sure that they have all thier stuff out of there and in storage or whatever. Then make sure that some idiot hasn't ordered everything that's going to be used on the remodel and it's all sitting in the way ( cabinets, bath fixtures, carpet, drywall, trim), all this stuff doesn't need to be there during rough-in but homeowners don't know that. Is the job being done by a professional remodeling contractor or a homeowner just hiring subs. Is the job going to be done in phases or all at once? Is there a good set of plans or is it going to be plan as you go?
Talk to whomever is doing the job and make sure they have a plan of action to actually finish the job. Then make sure there is actually money to finish the job.( It's a legitimate question ).
Once you know all the important stuff then you will get an idea of how much time and materials will be needed to complete the job. You can then compare this to the unit price for each device and fixture and see if you need to raise the price.
I like to know two things right off before starting a project. One is when they plan to start and the second is when the plan to finish. If they are professional they will have a pretty good idea of when they will be out of there. This makes it much easier to schedule the work.
Watch out for people that don't know what they are doing because they will drag the job out forever and you won't make any money no matter how much you charge.
