If you say utility bill - easy to photoshop.

I have $50,000.00 to invest and I found $70000.00 patio home. so I decided to buy with 20%down and get the traditional mortgage but quickly realized that I have to pay roughly $3500.00 load processing fee to get the either 15yr or 30yr loan. question #1 should I use HELOC(which processing fee is in 7 to 800ish) from my home to pay the rest 80% and try to pay off as fast as I can or just get the traditional loan and utilize the tax benefits?

Larger roof, more expensive fixtures, higher labour costs in more expensive markets.Keep in mind that everything about costs and income are extremely rough guestimates at the very best based primarily on industry data gathered over decades involving millions of investment properties. 

You can then bill additional fees/utilities, etc as needed.

It will be a good way to look for a mentor and meet people already in the industry. 

A little about myself, I'm an engineer working in the aerospace industry and I am here to start from the bottom and work my way up in the real estate world.  

Can we deduct our usage from their utility somehow?

How could I utilize my oarents’ ‘renter and landlord’ relationship?

Does anyone utilize a checklist when taking calls from prospective sellers in order to maintain consistency and gather only the needed preliminary information? 

As I understand it: As a 1st lien holder you are actually 3rd in line behind the County (taxes) and Utilities.
