$$ Into NYC Home Partnership or Stay With Vanguard?

[mookie]

We live in a multifamily property in Brooklyn with subsidized rent-mortgage about $1200 below market in exchange for managing the property. We have a minority ownership stake in the property from sweat equity, and our investing partner is amenable to us increasing our equity. The property has gone from $1.16 million a dozen years ago to $2 million. I think there will be continued growth but unlikely to match the initial dozen years. I'm wondering if it's a good idea to invest more (100-120k) in the property or better to leave things simple in index funds. On one hand this seems like an easy opportunity to build equity in a very good property. However, I have a more FIRE bent than my spouse and am reluctant to put more liquid money into the property. I would love to FIRE in 10-15 years. Thank you for any thoughts!

Specific Question(s):

What other questions should we be asking about the property to better evaluate the investment?

Should we put more money into this current investment/home? 
If yes, what's a reasonable amount? We were thinking 100-120,000 from the non-retirement funds.

Thank you for any thoughts!!

For FIRE you'd probably have to sell your stake. Is that something you are willing to do.

Right now it's $167,000 and $1,400 cash flow. For another $120k you could buy something like another $1k in cash flow. That doesn't get me super excited, especially with real estate that I'm would be a minority owner in.

My big question (red flag) is why is there a HELOC and where did that money go?
 
What are the other expenses on the building?

If the net cash flow is only $7000 on a $2M building I am very concerned where the money is going.

A good, but not exceptional, year in the market with balanced ETF could bring you $7000 on a $100,000 investment.  7%

$7k in cashflow on a $2million building is almost unbelievably crappy.

TBH, I'd be worried about actually being able to liquidate your "share" in this place if and when you want to move. I'd stay the hell away from putting more money in!
