@Cesar S. the important aspect to your post is "condo". 

I was wondering if anyone who has done this can tell me if after comparing price per sqft of the building aspect of the project only (cost of land, environmental remediation, and demo excluded) they have found modulars to be a more cost effective way to go rather than stick built.

I think I will go ahead and get my license as it sounds like it does help to understand the market and some other aspect as well.

I would hire or find a broker or seasoned professional that can satisfy that aspect. 

Some people like all the aspects of single family homes and others perfer dealing in mulit family complexes. 

Funeral service is great, I love the aspect of what I do but I hate that it comes with the price tag of always being there for someone elses family before my own. 

Have you done your due diligence outside of the financial aspect?

I have a large pool of handymen that cover every aspect.

all three are distinctly different in form and function.roofstock is more of a MLS type system highly automated representing civilian sellers by and large and some turn key companies will list their stock on Roofstock.. its pretty snazzy however after care is between you and the PM.Homeunion has some hybrid of turnkey marketing company in the same vane as Jason Hartman Maverick Norada etc.MI is what many consider the gold standard in turn key investing.. very deep experience in the space.. and control all aspects..

If you look at the very bottom line, the results are remarkably different.
