Would not advise doing your own walk-thru.

Did a contractor walk this property with you as well?

Is it better that the seller's mortgage gets paid (by someone else) and the property turned into a rental or should the seller simply 'walk away" and stop making payments and the property become vacant ?

I would bit up to 350k depending on how the walk through goes prior to auction.

A flipper I know didn't follow his recommendation and applied Killz (water based in CA) and during Realtor walk through, prospective buyers complained of cig smell.

I think it is better to connect with many GCs, find the ones you want to work with the most, and have them walk properties and provide bids for you.

Don't let your tenants walk all over you.

Had they refunded my tenants application fees I would have just walked away.

Most of their money is walking out the door unless they are there 24/7. 

If you do the latter, you need to screen the new person the same way you did the first person.I offered to let her have roommates, but she doesn’t want to deal with it because she has no one that she would trust to do it.She said “You know I have a big *** dog, but you didn’t know that I like to walk around the house naked too” hahahaSounds like I’m losing this one.
