Advice! Rent it and borrow money vs Selling it

[Tomas F.]

I bought a Property (Duplex) in Miami (Prime Location) in a Forclousure auction. 

Now I finish all the improvements and I don't know if selling the property or renting it and borrow money from the bank in order to grow in the business, I am new in this so I will appreciate your advice.

I bought the property a year ago at 260K I did everything from scratch, Electrical, Plumbing, Mechanical, flors, roof, etc (All with permits). I only kept the shell. I spend 190K so Property + improvements in terms of Investment is 450K the market price for that property if I sell it now will be 650 - 700K

If I rent it, The rent will be around $5000 Monthly (both units). so it will be 60K yearly and the management in terms of maintenance it will be low (Because everything is new).

Here is the question, What considerations I should have in order to decide if I should selll it or rent it and get money form the bank to grow my business??

Thank you!!
