I have a three unit property that I get about $1500 a month after PITI, and after factoring in repairs Im between $800-$900 a month.  

To help improve consumer clarity and promote industry compliance with TILA and RESPA initial and final disclosures, the Good Faith Estimate (GFE) and initial Truth-in-Lending Disclosure will be replaced by the three-page Loan Estimate.

Just left Chicago a month ago and miss it three months of the year so far.
