I can also get a co-signer if need be.

I have a CO LLC and have to pay yearly.

I don't know much about proprietary leases but apparently it's an issue for a co-op I'm thinking about making an offer on.I'm getting a mortgage through my bank, and when I approached them to check the financials on this particular apartment, they said the project was declined because it has a proprietary lease that expires in less than 30 years.

By "payee" do you mean a co-signer or is she actually on the lease?

The parents aren't an option, though we did look at family members either for PL or even a co-borrower in a pinch. 

I had an issue where my income wouldnt be enough for me to the high loan I wanted, so I looked into getting a co signer.

I recently bought my first personal property ( a co-op in Mt Vernon) but now im ready to start investing.

It's in a Living Trust for my mother's benefit and I am a co-trustee.

I am on Bigger Pockets because i want to create a reliable recurring income for the future.I live in a co-op with a mortgage and I also have 2 investment properties without liens.

Maybe bring in a co-signer/partner with income for the additional $7k personal loan
