Real estate is slower to get into so I would first look to switch job wise and see if you can get a a higher paying attorney job.

Yep no problem there as long as things line up timing wise.

The market doesn't care about your bottom line.

NOI is the line item left when ordinary expenses are taken out of income.

There's no real hard and fast way or only 1 way or doing your first 2 points. your subject line suggests you're not looking to go to a large shop like a JLL or a CBRE which honestly I don't blame you those offices are usually pretty bloated.As far as monthly costs, if you are going to individually get a costar or other such license you are probably looking at $500-$1000 a month pretty easy in overhead once you have office dues, mls dues, marketing, etc. 

@Kylie A.Yes, but have your lenders lined up before you dive in. 

What is your primary reason for wanting to pay off the mortgage? 

Or the listing agent.If you have a provision on assigning leases to the buyer and transferring security deposits in the Offer To Purchase (in Wisconsin that's part of the standard form) the title company will put the SD as a line item on the closing statement.

The other way I fund deals with none of my own money is using a private lender that I have years of experience and relationship with and/or using HELOC and other business lines of credit.

I would look for a low interest line of credit to put on the property and lend at a higher interest rate.
