Is there any recommended material I can absorb to help me achieve my goals?

So its not PM its the investor buying into tough management situations then blaming the manager..

The 10% is probably for ordering items and being there when goods arrive, unboxing and removal of packing materials, assembling any furniture that needs it, placement and moving things around, putting up artwork, and washing new plates, silverware, cooking pans, coffee carafe, prewashing all sheets, towels, and linens etc. 

The best thing to do would be to consult an attorney, but likely, that is not an option for everyone starting out.I'm not an attorney, and this is not legal advice, but some of the information that we include in our contracts is:- A clear scope of work - Payment schedule / Milestones- Change order approval process- Allowances for finished materials- Reasons to terminate the contract- Expectations for start date (X amount of time after final plans /permits are received or X amount of time after the contract is executed)- General schedule and timeline (This is where you could specify an end date - however it may be better use incentives rather than liquidated damage if your general contractor is late - we've done both, but found General Contractors respond better to getting something if they get done early instead of being punished for being late. 

@Daljit Singh, I'm sorry you are going through this, it's really tough!

Without that it will be a tough task to accomplish unless you work out some custom structure or bring the GC on the loan with you so you can leverage their direct experience.

If you do it yourself , you deduct the cost of materials .

Shorter term solution, probably could be done in 5 hours by someone handy for less than $200 of materials. 

@Alex CapozzoloI’ve learnt it’s really tough to use an accurate cost per square foot number.

People forget to read the PPM where it says about 10x you can lose all your money.47 units is very tough to manage.
