With that being said I am really not sure how to start this process.

My data source does not seem to show foreclosures in South Carolina at all.

Out-of-Town Buyers: I understand the unique needs of buyers looking to relocate or invest in Northern Michigan from afar as I personally went through the process when we moved to Traverse City in 2017.

I recommend you do this off platform because FF is clunky and slow and there are no penalties for doing so, unlike Airbnb- if it's a good fit for both of you, you proceed with whatever your process is (usually this will be an application, background check, lease, deposit)I say all this just to show that yes, it's cheap to list it there and in my experience it is VERY effective, but it requires legwork and follow up on your part.

I will be in the process of looking for my first rental property this year.
