Need help with what to do with this deal

[Antwan Smith]

I have a townhome that I am buying Sub2 with $1450 PITI loan balance of 190k I have it contracted for 240K, 30k to seller up front and 20k whenever I sell. The ARV is 359k (with about 10-12k fixup cost) and homes are on the mkt in this location btw 30-40 days. I am considering all options such as possible offering seller financing (but I am not sure how that works as far as what to charge), lease options, or rental which I can get about 1800 per month. If anyone could give me a little direction on what to do with this deal or have other options please let me know. I am schedule to close Dec 27.

Thanks,

Antwan
