Is this sentence correct?

[BuddhaGeo]

ニノの家も私のものです
Just in case it's complete rubbish, I'm trying to say "Nino's house is also mine".
And on a relative note, how does one say "I have a house".
Thanks in advance.

[Mike Cash]

Your sentence could mean that Nino merely lives there, while you own the house (as well as others).

[BuddhaGeo]

Doesn't "Nino no ya" basically mean "Nino's house"?
And would you be so kind and write down the correct way of what I am trying to say.
Thanks.

I'm not even clear on your exact English meaning, here.

Is it literal?
"Nino and I own the house together." (you both paid for it?)

Is it like the idiom, "My home is your home?"
"It's Nino's house, but I can come and go as if I live there too."

Something else like Mike Cash's message? I'm not good enough to help with the Japanese, but this info may help someone else get you the right phrase. ^_^

Sorry, I've just noticed that I forgot to add 今.
So basically what I wanted to say in the very first place was "Nino's house is also mine now".

[NocturnalOcean]

Wow that really helped, I am so glad that you found the time to add 今, it makes much more sense now.

This is a common mistake, but if I'm understanding your English sentence correctly, then you have your 「も」 in the wrong place.

The sentence as you wrote it would mean "(In addition to other things or other houses that also belong to me), Nino's house is also mine."

I assume that what you actually mean is, "Nino's house is also mine (in addition to it being Nino's.)"

That would be 「ニノの家は私の（家）でもある」

If you want to add the meaning of "now", then　stick an 「今は」 in there -- 「ニノの家は、今は私の（家）でもあります。」

Also,

Doesn't "Nino no ya" basically mean "Nino's house"?

「家」 in this sentence should be read as 「いえ」 or 「うち」, not 「や」
