Is there benefits to loans for small multis cashflowing $750 per month.

That's one of the biggest benefits of house hacking. 

Hi BP,The scope of knowledge I think are essential for me to get my first deal is narrowing and thank you very much for contributing to that. 

Title insurers have essentially been forced to remove the survey exception from lender's policies so this generally only affects owners policies... but like I said, once a lender is aware of a title issue they want it resolved or insured over before closing.I would never purchase a property without either (1) a new survey or (2) a fairly recent prior survey + a survey affidavit.

Are there any tax benefits with notes?

The added benefit is I get a good sense from a wide range of properties are available.

This is one of the greatest tax benefits of real estate investing as it avoids capital gains taxes.

What's the best way to handle this and ideally reap the benefits of the cashflow and sales proceeds but also the benefits of the LLC, if its even worth it....?

haha... think Barclay's Center, which hosts the MTV awards, Williamsburg which is the Mecca of Hipsters before much of other Cities became well known as Hipster havens, tons of Celeberties live here, etc.Basically, Brooklyn had benefitted from the Maturing of Manhattan which became a place of the super wealthy.

I've got a rental to sell so instead of 1031 exchange I'm hoping to reap the benefits of this tax change, we'll see.
