I have read and am currently reading books on real estate and real estate investing.Following my readings up to date, I am considering house hacking for my first deal in real estate.

------------------------------------------------------------------------Here's our current guess: "The builder's plans and the build may not line up perfectly, so the buyer could sue for breach of contract or a similar claim."

However my market is currently Arizona.

I currently have a portfolio of SFH in Indiana and will always jump on a good deal for a SFH but I have been considering scaling up into multifamily commercial real estate (apartments, etc.)

Will be difficult because you currently live in the property . is the 2nd unit livable and just looking to renovate ? 

I'm not sure how the current political impacts this.

It is a goofy idea but it is currently being explored.

However, my debt to income ratio with that home loan, and student loan doesn't look that great currently and I don’t have much for a down payment.

I have 3 properties and currently looking to sell one. 

Operating an Airbnb business requires being up to date on current local ordinances and restrictions.
