Back Taxes on Pending Sale

[Cameron Parr]

Good Day Investors,

I am a new investor and under contract to purchase a duplex in Rochester NY. Property has a back tax situation as reads below. 

My realtor addressed seller about the taxes due and they agreed to pay outstanding taxes from proceed of sale. Has anyone ever heard of this practice? Are the taxes going to have to be paid at closing by me and reimbursed after? Going to meet with realtor and do inspections soon. 

Principal Due:	$10,988.71
	Interest Due:	$1,503.52
	Total Due:	$12,492.23

Thanks,

Cameron
