After discussing my concerns around the current market conditions sorrounding COVID-19 with my agent, she mentioned if I were to cancel the agreement and terminate the contract that in addition to losing my earnest deposit, I would also be liable for buyer and seller broker commissions. 

Landlords may lose some rent or need to allow delayed rent payments.  

It is cash flowing nicely with a good tenant who currently does not have fear of losing their job. 

The last thing we need is landlords going broke losing their hard earned rental property investments.

If they don't execute in x amount of time then they will lose their deposit or will have to renew until they can get financing.The second idea for a longer-term: if they can't qualify for a loan he can do a wrap-around mortgage with his.

Sure they could show that they have made $100k per year over the last 3 years but with the way things are, could they lose their job?

The owner posted a FSBO and i contacted him asking if he was willing to sell. i am completely unsure on how to run comps on this property. its strictly commercial, it used to be a barbershop. how would  i go about not losing this lead and making a solid but fair offer in which i can wholesale it and still allow the buyer to make a profit?

The last thing a someone wants is to lose their home so rent should be a top priority.

List it for sale, what do you have to lose?
