I'm really interested in hearing directly from professionals in the field: What are main challenges contractors and developers are dealing with on daily basis while building homes?

I've only experienced this on the buy-side of multifamily acquisitions, but have been involved in transactions where the lender requires a CofO and they have gotten comfortable with just the I-card, when there is no CofO for the property. 

You can't control everyone everywhere, especially if you have mid size team and hundreds or thousands of customers who submit tickets on daily basis.

All I am asking is a reference to a bank that has a good web site that will allow me to do all my online transactions and be easy to work with.

Not every lender can write mortgages in a way that support our transactions. 

The same is true of seller financed transactions.  

I feel like just about every month, I see RE investors with 1-2 year's experience starting a new fund and advertising on Facebook for LP's, as well as the daily "JV deals" that straight-up violate securities laws.

I'm not against hiring people without a solid estimate for the whole project but then it just means the work is paid based on an hourly / daily rate and I get daily updates on the progress and I watch them very very closely.

Energy cost affects every aspect of our daily lives.  

This is more common that you might think.They do not take into consideration the costs borne by the investor associated with the transaction such as: closing costs, carrying costs, finance costs, exit costs, etc.They are trying to hit a homerun on every deal and not leaving enough "meat on the bone" for the next person.
