At the same time, I would hate to loose on all the equity on the investment property if price goes down. 

Prove how this 1 simple fact listed below is wrong, that by following the basic standard investment real estate practices as defined ins standardized investment property finance for leverage and standard practices of operations etc. that all one has to do is WAIT and not only not loose $ but will profit, is incorrect. 

If you are not ok with Step 1, want daily updates, want to participate in all construction meetings, ask for copies of paid invoices once a week, go do random drive by’s and ask why a porter potty is not where you think it should be, or why there is a loose nail in the driveway that was left behind by a contractor you are not trusting your manager and micro managing.

Looking for a HML that will meet your needs is key so that when you find a deal, you are not scrambling looking for financing and loose the deal (happened to me early on . . another investor got a heck of a deal). 

I cut the excessive expenses such as payroll and overspending on materials and vendors.

It seems excessive.

So many people drag their feet and loose out on great deals.

I will like to talk to someone with experience so they can guide me on having the project finish with all the legal permits but with out loosing to much money and most important what do I do with this person that is trying to take advantage.

In case you get a low income family who doesn't treat you stuff nice, at least here, if I evict them or they violate my lease and I let the city know, then the city will take them off of rent assistance. and that is a benefit most families on rent assistance absolutely do not want to loose.
