Creative financing - advice needed

[Jonathan B.]

Hi Guys

Have 2 different cases and wanted your opinion on show I should get approach them

1:
Duplex, Titusville in Dixie HWY seller owes 70K, wants me to make an offer, doesn't want to give or doesn't know the PITI until I make an offer -
Section 8, rents are in the 600-700 a month in the area, hard to tell.comps -
Wants cash - should I wholesale this or try to offer a small down & offer to pay his mortgage? What else?


2. 
Townhouse , 2bd , HOA 50$, Rents for 700-800, seller is asking 70K and is uninformed, comps are maybe 25-30k below his asking
Seller will do owner financing 
What terms should I get even if the seller is firm on price? Should I even attempt with terms if the price is over market? What else should I consider?

Thanks a bunch guys
