Newbie wholesaler to investor/rehabber question

[Ronnie Gilmer]

I'm a newbie to wholesaling and i am scouting to potential run down properties that have been vacant for years. However I don't know if the two properties are worth pursuing because of the age and damage to the house. Below are pics of both houses 

House 1's structure was built in the 1860's. The main problem is you cannot see it due to the growth around it. Note: this is a historic town where the comps are selling for the high 300's

House 2

This is an older pic i pulled from the net, after doing a drive by the house is almost covered. 

Can someone advise on whether if these could be saved.
