Wholesale It or Rent It Out?

[Lamond Sykes]

Newbie investor from St. Louis looking for some advice... I was driving for dollars and came across a FSBO sign. Called him up and he’s asking 32k. ARV is around 34k. Been trying to sell it over 60 days. My max offer is 21k. He currently has a tenant paying $550 a month. Market rate rent in the area is $750. My question is if he accepts the $21k should I flip it to another for $24k-$26k or should I take out a mortgage on the $21k make it my first rental property? If I were to keep it I’d raise the rent to $650. Any thoughts or ideas are appreciated. Thanks!
