Offer & Factoring the Fee, 1st deal

[Keya Hill]

Morning! Im scheduled to view a house 4b-2ba 2208sf.  Asking $125000. Mao is $153000 w arv of $252000.  House needs cosmetic work.  Roof is 3yrs old. But a duplex behind the house thats rented, comes with it.  Havent seen it at all yet.  How would I factor my fee into this? Hoping this is my 1st deal.  Would I do a double-close? Would I need 2 purchase agreements since it's 2 properties? Thank you!
