Some will suggest making an offer contingent on a unit being delivered vacant.  

Be aware of and use contingencies to ensure you're really getting the deal you want.

Before I bought, I would have that clear title as a contingency clause in the purchase contract that has no penalization statement in it that allows you to say "no" when it is checked by the Title Company or an Attorney's office. 

I'm not saying it's impossible, we just had a similar situation with a client and we were able to get him under contract, your agent will definitely need to know how to maneuver this issue and find ways to make your offer more enticing, whether is by waving contingencies, offer a higher down payment, etc, not saying these are the best ideas, but just some ideas to ponder. 

@Timothy M WeberAs a contingency I would certainly want to look the leases in detail Look them over Good *before I agreed to the sale I also would specify that the seller is to give notice and get sIgnatures to all tenants in any and all units involved that they must vacate and the lease is not being renewed .

@Carlos Araujo: I don't know which part of NY you're investing in, but standard downstate contracts allow for financing even if the deal is not contingent on financing. 

just include inspection, appraisal, and financing contingencies...

Make sure you Purchase and Sale Agreement has contingencies for inspection and partner's approval.

I just see so many idea on here for the person with little to no money to get started that put all the risk on someone else...Get it under contract with a bunch of contingencies so you can back out and then shop the deal even if you have zero money.

Is it common, when makIng an offer on a commercIal multIplex, to place a contingency for all of the units to be under lease agreements?
