Can't Find The Owner (Behind an LLC) of adjacent property

[Victoria Price]

Hello!

I am a real estate person in Brooklyn, NY. My husband and I just bought a beautiful brownstone, and the adjacent property, the identical to our home is falling into disrepair. I have spoken to the city, I have reviewed Acris, and the taxes are being paid by an LLC. Does anyone have any ideas for how I can get int touch with these people (behind the LLC?)? I can't find any way to locate/communicate with them...

Any help/ideas/suggestions would be greatly appreciated. We would love to invest in and improve in the proerty next door! We just don't know how to buy it!
