So the current owner bought from the developer when the property was 3 years old then?

You can take a look at its economic development site to learn more on it.

(there was a tiny set of stairs also)The developer told me there was also an alleyway down the side of the building that could most likely fit a wheelchair and had direct access to the condo, so it's possible that would satisfy the ADA and they could remove the ramp on the inside of the unit.I have never dealt with a property like this before, so I'm wondering, who do I talk to to make sure this unit will be ADA compliant? 

I've not heard of REI Nation, are they a turnkey rental developer?

What is the average gross revenues for other condos in the development/ location?
