Here are few ways I thought of:a) Purchase 3 properties in mid-west, about $70~90k each would produce maybe $600-800 / month rent.b) Purchase 2 properties somewhere (I don't know), preperable in A, or B class neighborhood, each cost $100~$125k, and can produce $1000+ / month rent.c) Purchase a property near my cousin's backyard, which may cost $400k+ and can get $2000 / month rent.

Because of background in contracting, a hot market, and our hustle each flip produced very good profits.

QuickBooks should be able to produce the income statement, statement of cash flows and balance sheets.

Specifically multi family is valued off the income it produces, where 1-4 units are valued based off of comparable sales in the area. 

Option 1 seems good because the loan pay down alone is 15 years faster, but ob,y produces $200/mo cash flow.

I have a portfolio of about 20 individual rental income producing properties (some SFH, townhomes, and a couple condos)..... 

To me, that means these repairs are coming out of your pocket.Of course you could follow your state guidelines and keep some of the deposit for repairs, but if they are smart they will take you to court and produce the document that you signed.

Maybe you can choose a city or a few that you think would produce good cash flow and start there?

You'll probably produce enough cash flow to live for free (or cheaply) and learn the landlording business.

Moral of the story, that workbook doesn't work correctly nor does it produce the correct numbers.
