The main question we have is how high is it worth going now, and how much negative cash flow should be tolerated (if any) for future upside?

The accessory dwelling unit shall utilize the same vehicular access that serves the existing main dwelling unit, unless the second unit has access from an alley contiguous to the lot.

@Jason DiClemente My main concern was the fact that I actually couldn't get them turned on immediately because I was missing a doc when I went in to do it and then the next day they were closed and now it's the weekend...however, I hadn't considered what you just pointed out.

And my main question..how do you go about it?

With that being said, I'm wondering if I should end the lease in January and start the BRRRR (mainly the RRR part).

This is a general message mainly because you have given general information but build rapport with the seller as much as possibleand make sure they are confident of your execution to pay.

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.
