Property Analysis- 2 units on the same property

[Joshua Richter]

List Price: 150k

2/1 SFH - $1200/month rents

1/1 Mobile Home - $1000/month rents

Ins: $100/month     Prop Tax: $150/month

Home seems to be in fairly good condition. I am estimating less than $5k for touch ups.

The SFH is currently not rented, but mobile home is. Both are metered separately and tenants handle their own utilities.

Seems to be a C neighborhood. 

Expected CoC Roi after PM/Reserves: 35% ($987/month)

I NEVER find deals on the MLS. This seems too good to be true. What am I missing? What questions do I need to get from the seller? I know I need to get an estoppel to prove rent of the mobile home unit.
