I was not able to buy a duplex, triplex, or quadruplex since the mortgage would've been more expensive, but it was my first idea. 

you will want Handyman insurance, and as @Glen Morrow stated, you will not be allowed to pull permits, per state law, you would need a contractors license to pull permits, and technically to do work on a 1-2 family dwelling. to get the license you need to complete a 12 hour training, and pass a test, and have appropriate insurance, Quite expensive insurance at that.

This is a business at the end of the day.I don't walk into a Lambo dealership and expect them to hear my sob story as to why I need a more expensive car over a KIA that I can afford.

Getting your Real Estate license is a great idea for flipping houses you will be able to save 2.5-3% when you buy (if listed on MLS) but definitely when you sell which is a nice added cushion in case unexpected expenses come up especially when starting out!

More expensive because you couldn’t use the old foundation.Hard pass and don’t look back. 

I'm not looking to sue people and get tied up in expensive litigation fees but is it something I should consider?

Stay financially disciplined and plan for unexpected expenses.

I'm bringing in temporary rental housing to cover expenses while investigating building the first permanent home.

@Seana Yates While people structure partnerships anyway that they find acceptable, here are some concepts to consider:Your "sweat equity" is great because it saves you in expenses. 

HI John, You can always start off by house hacking meaning you live in one UNIT or ROOM and renting out the other vacant units/rooms to offset your monthly mortgage payment.There are several ways to run and make sure you are maximizing your rental income while keeping your living expense as low as possible.
