Shelby, the question is: Why are you considering selling your condominium? Renting is always a financial health situation whereby you are protecting your assets as best as you know how.
The next question is: Can you afford to do a discounted rental on that unit as some have suggested?
How well do you know the current tenants and will they cooperate with the sale of your condo, should you decide to do so during the term of their rental agreement/period?
Flip side of the coin: Would those tenants renew their lease even if it were on a month-to-month, knowing that there is a possibility of you selling your condo?
The question you ask is: "Can/should I put in a clause that I'll pay each tenant some inconvenience fee if they do need to move out?"
Yes you could put in a clause but you need to be specific on the time frame of notice to move, when they would need to move out (prior to closing) and depending upon how many tenants are in the unit, pay for their moving costs which could run you $500 plus for each mover, depending upon where the tenants would be moving.
You also need to consider that you may need to "spruce up" the unit just prior to closing. So I would allow time for that as well.
I hope this helps you. If you need verbage for the clause, I strongly suggest you get an attorney in who would be handling the sale of your condo to guide you, to make sure you don't get caught in a bad situation should you decide to sell.
Best of Luck,
