It can be very different from a condo to a co-op even though the actual structure is the same. 

I am in the process of closing on a property but unfortunately my personal credit was hit and now in order for the closing to happen I would have to have a co-signer on the loan and line of credit. 

Definitely don't plan on waiting until my credits repaired enough for them to start approving me for refi loans using that strategy...so I was wondering if there was any other strategy with using somebody as a co-signer such as my money partner who's got a W-2 job?

A co worker of mine approached me about the empty lot we own.

When I apply for mortgages, there is usually a space for a co-applicant.

One option I have employed is ask for a co-signer.  

We have a co op in NYC that we have rented for the past 2.5 years.

Perhaps I'm being dense, but it seems that if the property is in the LLC and the mortgage is in my name, then (a) there's a co-mingling which might pierce the corporate veal and (b) the LLC's balance sheet would inaccurately present a debt-free asset. 

If credit is the only low thing and you still feel good about them you can require them to put in a higher deposit or to get a co-signer for the lease.

A co-worker asked if I'd considered just building a new one.
