It's a complex topic, you can definitely learn more about the basics from YouTube videos. 

QOF can be very complex so best to work with an accountant who understands it.Best of luck

I'm over 50, but I still pass everything through the "Court of Mom".

You should work with several professionals to guide you on the specifics - attorney, home inspector, CPA, there are a lot of complex issues involved here.

@Bharath Mun - I am going to repost one of my comments from a few months ago about Decatur as an FYI for you.Original post:"I have lived in north Alabama for over a decade - in all the years I've lived here, the only reason I've gone to Decatur was for the kids soccer games at the Jack Allen Soccer Complex (which is quite nice).

Complex construction projects are the easiest way to lose money, and the toughest for inexperienced investors to be able to pull off.There are a lot of inexperienced contractors as well who will gladly give you a quote for $50,000, get half way through the job and not be able to complete it or need another $50,000. 

I’m also open to looking at just the apartment complexes or just a couple duplexes at a time.

Hey there @Owen Hawbaker I live out here in East Tulsa and I manage a small condo complex plus I have some rental properties out here.

It is always a possibility that the tenant does not vacate and you end up having to involve the courts, and in the meantime the tenant that signed and paid could sue you for performance and you'd have to sue the existing tenant to recover those funds. 

Or is the main  argument for MFs over SFs that an investor can gain experience with say a quad and then move on to a >4 unit apartment complex - so potential grow really big eventually?
