A few things to flag before the DM requests start coming in.
The assumption doing the most work here is ARV, or more precisely the absence of one. A turnkey listing framed for a landlord buyer runs on cap rate, not on rehab math. At $107,000 with rents in the $1,100 to $1,400 range, the gross yield sits between 12.3% and 15.7% annually. That spread is wide enough to mean very different things to different buyers. A Section 8 landlord buying at a 7 cap and a flipper underwriting a 10 cap are not the same conversation, and your buyer list needs to know which one this property actually pencils for before the proof-of-funds clock starts.
The risk you have not mentioned is the assignment clause. Memphis deals on fully renovated inventory move fast, but if your purchase contract does not explicitly permit assignment, or if it contains a clause that restricts or voids on assignment, you are holding equitable interest you cannot transfer cleanly. Confirm that language in writing before you market further. If there is any ambiguity, an attorney needs to look at it, not a forum.
Also worth confirming with your title company: Shelby County closings in Frayser can carry inherited liens and municipal code violations that do not surface until title search. A clean renovation does not guarantee a clean chain.
The five-day proof-of-funds window is tight. That is a reasonable structure if your buyer list is warm and pre-vetted, but if you are building that list at the same time you are running the clock, the timeline is working against you.
What is your assignment fee built into that $107,000, and do you have a buyer already circled or are you marketing open?
