So as far as where my money came from will that need to be accounted for? 

I'd suggest trying credit unions as they are usually flexible with the minimum size.

There are no ‘one size fits all’ warning signs.

Loan Size: Minimum & Maximum ?

Since I can't include expenses for my unit for tax purposes, I'm wondering how I should handle accounting for my unit.Should I pay rent from my personal account to the business account and then let the business account handle ALL transactions related to this property?

By your account it's the 15th of the month & you've already been notified of the payment issue, yet you are also upset that you haven't been notified of the payment issue.

The size of the company is not as important as what you will take home at the end of the day.

The most important thing is networking, Bigger Pockets is great and there are a bunch of groups on Facebook I could recommend but, you need a local accountability and an REI meeting would be the best place to find good people and find someone to help find the information you need and someone(s) to be accountable to.

Account ClosedHave you connected with a real estate agent who focuses in the area?

I recently heard of a conference with top real estate executives that had a panel of 5 millennials.The millennials sat on stage and these executives asked them questions about where they eat, what they do at night, where they want to live, etc.How often is everyone taking millennial activity into account when making investments?
