OP ignore what i wrote plz.

Kyle, if the OP does a Recast it will change his monthly payment; generally, $50/$10k. 

OP, please excuse the hijacking of your thread.  

Condos that are owned as Co-Ops can be even trickier with financing and common property ownership, and are admittedly out of my expertise.Hope that helps.

Assuming the OP's LLC owns the properties I can't see where a separate account is required for security deposits. 

@Ron Todd, This is more specific to you rather than the OP, but one thing to keep in mind is that it seems (at least around here) that lot of commercial lenders don't like series LLCs.

I'm interested on buying a co-op investment property for a BRRRR (my first investment property in the US, $250k asking price, $400k ARV, $50k rehab costs), but I'm not willing to pay cash for it. 

My point is seller does not want to accrue legal fees any more than the OP.  

I think that changes too, once more people realize the benefits of moving elsewhere, but the OP said 15 years, and I don't think it shifts that quickly.....

I am replying for the benefit of others, not the OP, as you have to identify within 45 days of the sale closing.
