Need help with mortgages, liens, etc

[Jack Phillips]

So I have a hypothetical situation:

Lets say a properties ARV is $550k,

Repairs are $75k,

And Wholesale Fee is $10k.

Using the mao formula:

$550,000*80%-Repairs-Wholesale Fee = MAO of $355k

When I am making my offer price to the homeowner, how do I include any liens, mortgages, and/or money owed? Do I subtract the the offer price ($355k) by the total amount of money they owe? Or is that not my job and I offer the full $335k to the homeowner, find cash buyer to buy the property, and the cash buyer and title company deal with all that.

Please help, thank you
