1st House for 2012 GOING - Signing papers tonight

I picked up my 1st property for 2012 beginning of January. I paid the owners $1,000.00 for the February payment, since I was not giving them a down payment. Tonight I am signing a 3-year Lease Option with a family. I will collect $3,750.00 down payment. I will also collect $460.00 pro-rated rent for February. Minus my $1,000.00 down for the February payment I made, I will come out $3,210.00 cash in hand. I will also collect $150.00 positive cash flow for 3 years. If all goes well and they buy in the end, I will make an additional $14,000.00.
