It appears that rentals are allowed in the building, so either ask your agent to get more information from the management company or if you aren't working with an agent, I'd be happy to work with you to help you find the specifics out about this building or any other possible investment opportunities.
Feel free to reach out to me to discuss further.
5701 does allow rentals 100%. I am a preferred listing agent by the management company. Over the past two years I have helped them to increase the rentals prices by 25%. Please feel free to contact the Sudler Management company in the building to confirm what I am telling you.
Also I can give advice on what needs to be done to the condo to get top dollar.
