Question regarding outstanding tax and condo liens

[Jochy Perez]

All, 

Have a property to purchase, however, it has a tax lien and condo HOA lien at the moment.

Is it possible to write up a PS stipulating these expenses will be paid at closing or do these need to be settled first before? 

Just trying to see if I can add those fees in to the PS as part of the purchase so I can finance the cost. 

I'm thinking the condo lien I can't since I will need the 6D to close anyways but taxes might be doable.
