Newbie doesn´t know what to do with 2 properties

[Marlon Palma]

Hi dear friends,

I want to become an investor, I have two houses already. I´ve been trying to sale one for 18 months but cuz a document that gov can´t issue I haven´t sold it, it is new almost 100% finished. it is located in a very danger neighborhood but in front of a University. The second house is in a mid class neighborhood and docs are in order, the price is higher due to the area but I wanted to sale the first house to build some apartments in the second one property and rent them. Now my plan doesn´t work cuz I can´t sale the first house, what should I do? Plan B sale second house and build apartments on the first one even when rents are going to be low? I need help and ideas please!!
