@Joshua TanWe have access to a Landlord insurance program that includes 2500 deductible, 1 million liability, replacement cost, loss of rents, and water back up that is very competitive in price.

With this being the case, that means that the most that the lender will give you access to is 85% ($205,600) of $257K minus your current balance of $138K which yields $6,600 under the best-case scenario. 

Totally agree about the access to CTA lines--one of the greatest benefits of living in the city--having a world class, reliable public transportation system at our disposal.
