So, let’s kick off this last chapter by learning how to squeeze every last drop of potential out of every property.Adding Additional Units.

I don't have the 10% for the down but thinking of using a HELOC to get the money and then add it into the calculator.

Then they'll charge an additional $2,400 for filing tax returns. 

Quote from @Kyle Schachsieck: Thank you all for the information and additional resources!

Do they value nicer finishes and design or is that additional cost lost on the typical tenant in that pocket?

.- Tell them they'll have to provide you with a copy of their renter's insurance naming you as additional named insured, with a minimum of (I use $300,000) liability insurance, also before they move into the unit.It's not perfect, but it's a start toward a tenant transparency.

What type of strategies are you exploring?

Several options you can explore to get the down payment capital: Solo401k; HELOC on personal residence or from equity of the SFR; Cash Value Life Insurance Policy; Business Credit; Private Lenders, to name a few.

After some additional research we have decided to focus on the aforementioned markets, but I will keep you in mind if we decide to look at Columbus more closely in the future. 

You would also want to add the LLC entity as an "Additional Insured" party onto the landlord insurance for the property.
