I really would love to get into some type of Real Estate investing, rental properties, flips, development, multi family, etc, but I don't really know where to start.

Plenty of pockets friendly to those sort of developments in Texas.

Lets say a land owner wants to enter in to a JV deal with a developer where the land owner only wants to contribute the land as his investment and wants to do nothing else.

I do see newer development on the due west side of town near Lackland, which makes me wonder if this development will keep moving downwards and perhaps the Southwest side will benefit?

KB Home, as it’s named today, began by developing starter homes for baby boomers in the Detroit suburbs.

To determine if it's worth doing a 4-Plex in addition to the cost you listed, I would recommend looking at; is the lot already graded, and ready for construction, are sewer, water, and gas already at the lot for connection, what type of rents are on your proforma, the biggest one many people forget about are the developer fees charged by the municipality to allow you to build the project, etc.There are a few soft cost items that will be a part of the project that do not get lower just because you're doing a smaller project.

I am looking to also create a solid foundation with a great team that can help me develop a portfolio of properties.

Depending on how it is titled and whether or not it is in any way developed (cleared, utilities, road, etc.) you may be able to extend the Liability from your homeowners or businessowners coverage.   

I'm looking for recommendations on an experienced builder who can help with parsing through and understanding the other multifamily development requirements and variance rules to see if what I've done as a prelim design is even possible, or if I will eventually have to plan on a duplex instead.
