I'm looking at infill lots in south miami dade county in areas like florida city, homestead, etc for joint venture projects with investors to build single family homes and small multifamily homes. 

If it is then spend the time getting the RIGHT education, building capital reserves, making contacts, and arranging financing options.  

My goal is accumulate properties while I’m still living at home, to eventually be able to fund building my own house with the cash flow from the properties.

you have to look at your building code and talk to GCs who have done it.

It is a full-time deal, and you will need to build your pipeline of clients for the next 2 years.

*This post does not create a CPA-client relationship.

Total build costs of 600k )this includes lot, soft/hard costs, and 60k overhead recovery to my construction companyAmortize @ 20 years, all expenses equal gross rents so break even cash flow.

Moreover, neither party seems very interested in my goal to build my RE portfolio. 

My concern is the HOA and state of the building.
