@John Choe, What I do with potential clients is sit down and have them pencil out their income/expenses/allowances on the property they're wanting to sell so they can have an accurate picture of what they're true income/return really is. 

The owner just repeatedly paid the (steep) fine and returned to business as usual few weeks later.

Most multi families that have the best returns (only considering anything that will cash flow $100+ positive/month on a 15 year fixed rate while still living in1 unit after all expenses ) are anywhere for 80,000 to 180,000.

In your mother's case, it appears that she has no intent to return to the home so the life estate may be defunct. 

Usually your broker provide an extensive training - you don't need any paid coaches.If you're currently with a small broker, try to switch to big chains like Keller Williams - they have excellent training.No need to pay for training when you already paid for your RElicense.I used to pay for Zillow/Trulia/Realtor leads - it's useless, almost 0% return on my money.When I switched to big brokerage, I've got so much training that it all worked.

I suggest you be the property manager to get some experience and save money.The returns and locations C neighborhood looks fine. 

Quick Numbers..Currently Invested:  $270,000Rehab: $210,000ARV: $580,000We are offering 10% cash on cash return to any money invested. 

One is 45,000 square feet, the other 2500.I am looking for input as to whether you run: -personal credit report-business credit report-request tax returns for personal and businessAll of the above?

Your actual return on that property is pretty abysmal as a cash on cash number. 

(This year I made 40% return and 15% over 5 years so I did really well)3) My money in the market COULD keep earning above what I pay in interest?
