They had one issue many years ago where the main line froze and it cost them a lot of money to fix.  

I started a Partnership with some friends and relatives who mainly are Stock Market Investors.The purpose of the Partnership, in this case an LLC, was to purchase a $1.5 Million 3 Family in Brooklyn, All Cash.3 months ago I told everyone to pull out their cash in the Stock Market.They completed their stock sales a few weeks ahead of the Market falling off the cliff.I then closed on the 3 Family at a very good Price, collected a $40k buyer's commission as I am also the Buyer Broker, and just finished renting the 3 Units, signing the last apt lease in a few days, getting approximately $6k per month in Cash Flow for the 1st year.Not only that, I am securing an Investment HELOC at a 50% LTV, so roughly $750k, which I can use to investing in the Stock Market.I had already anticipated the fall of the Market as the inevitable Corporate Tax breaks had to wear off eventually.There just isn't enough consumers that benefited, in my opinion, therefore Corporate Revenues cannot increase and profits has to either stabilize as the max Corporate Tax breaks levels off.Really, only one way to go.I am anticipating the decline to last for a while.As an Trader, however, I will eventually buy long term growth stocks but also hedge it with PUTs in case I get in a bit too early.My friends and relatives are ecstatic as they probably saved a decline in their net worth by as much as a $1 Million.BTW, there is an old saying, "It is easier to make the 1st Million than it is to keep the 1st Million."

You just gave the main reason why both rules are, "porcelain bus" material. 

TREIA is also a great place to meet other investors, although I find the subgroups to be way better than the main meeting.

That basis is allocated between non-depreciable land, depreciable building and components that are depreciated faster.

You are not doing a big Rehab where you replace major components.  

If you were to attend what would you want added to this event and what main takeaway(s) would you want to get for attending?

@Rupert GrantGenerally if you're eligible for a Solo 401k, it makes sense compared to a self-directed IRA for many reasons: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.You can borrow up to $50k from the plan; IRAs do not allow participant loansThere is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)The one exception I can think of is if your primary goal is to self-directed Roth IRA funds.

Within the last 2-3 years, real estate investing has sparked a big interest in me and I know this is one of the main routes I want to pursue to make a living.

@Dylan LeBlanc yes those are the two main options
