Buying Low income properties ?

[Jake Diamond]

I have an opportunity to purchase 2 properties (One 3 unit & 1 two unit) both full rented in a low income area. Houses are side by side to each other. The owner is willing to owner finance at $90,000 for both with 5% down at 4% interest for 5 years. Houses are in fair condition obviously this would be pending home inspection given there was nothing major wrong with them. Thoughts on low income neighborhoods and what are your thoughts on this deal ??
