With multi units the wall separating the units is usually fire rated and typically you would not be allowed to remove/disrupt that rating.

To try to help with your question - here are some points I would suggest:Transition time - the transition from previous owner to new owner occurs at closing not before so if you were my client ( I'm a Realtor) I would advise that you do your best to ensure that any disruption caused to the tenants during the transaction period be kept to a minimum - your Realtor can assist with this - request that contractors that need to work on the transaction - inspectors, termite companies, roofers etc. visit at the same time. 

Checklist...1) The federal government has mandated the Defense Production Act, which gives the government ability to tell any corporation that they now have to work for them and do what they demand. 2) The federal government is rejecting our fourth amendment to due process.3)  The government is artificially propping up particular sectors and corporations of their choosing by giving them billions of dollars. 4) The government is buying out ETF and shares to the point where the stock market doesn't even come close to matching the climate of our actual economy. 5) The government are now disrupting businesses by telling them they can't operate until they say so regardless if they can survive or not.6) The government is now telling landlords that they are forced to run a homeless shelter instead of a business for the time being.

Also with the high possibility of a 2nd wave in the fall disrupting the economy again, i think we will see further drops.

Speaking of movies, it seems as Hollywood will get a reprieve from the Academy Awards annual disruptions this year.

Too disruptive, too noisy and too much risk and liability.

I wouldn't disrupt your financing until you understand how hot the market is right now for investment properties and that you will need 20-25 percent down to get one.
