Seller financing cons

[Nicholas Adams]

Hey BP community, I have a single family home in a C neighborhood. It’s in somewhat rough shape but I listed it last week off market and have a few offers. I started at 15k cash and got an offer from another local investor who offered 7.5k cash or 15k seller financed over 4 years at 5% interest. It sounds somewhat appealing (other than the interest rate) because I haven’t had any cash offers even at 10k yet and definitely don’t want less than that no matter what. Please tell me all possible cons/ worse scenarios to help me have some more insight before deciding! Thanks in advance!
