I own a mobile home that I rent out and I am looking to make my first MFH purchase this upcoming year to house hack. 

Getting the federal return correct is the most important and with owning two properties, there could be some positive tax benefits.

And then you can use that information to start to develop your own personal due diligence method: Crowdstreet.com, 1031 Crowdfunding, Akr7, Finresi etc.

The single biggest issue in my way currently is obtaining enough cash, whether it be my own, or through partnerships or family/friend-based lending (which I am very hesitant about to begin with as this could potentially strain relationships unnecessarily when money is involved).

Usually they don't own anything to attach it to.

Given many are returning to offices, would Austin still be a good market to invest and own?  

I'd also suggest Union City, where my wife and I owned a condo.

Also important to start using sooner rather than later stessa.com (for propertfolio mgmt) and hoah.live an HOA aggregator (in case you own properties in HOA communities).

Has anyone used e1031xchange owned by the law firm of Jerry M.

I do have a good idea of what you will explain to me regarding my permit as I have been in constant contact with permit coordinators and reviewers alike however, I am eager to hear if there is anything new that I haven't found out on my own.
