My own two cents on that, I used to sell power tools to Home Depot at a corporate level.  

Your successor trustee does not have to be your spouse, it can be any person you desire or even a business (corporate trustee).

I’ve read a lot on real estate investing but I’m still unclear on what the advantages are between an LLC, corporation, etc.

If that's not your property, then it's not showing up.Bottom line, starting from Zillow, search like you're a renter for a corporate rental in your area.  

Title chain is easy to follow anyway.....a few minutes on your state corporations website tells us whose LLC it is.

I also included painful reasons such as not wanting to reach 80 years old and be filled with regret and the possibility of working corporate and not having time to hunt as much as Id like (my passion).

If you consider your portfolio as your corporation, all you really need to do is look at how the world's most successful corporations operate (other than ruthlessly slitting the throats of their competition!).

I would like to supplement my FT corporate income with this method of real estate investing.

FHA and Fannie won't lend to a corporation.

I would only recommend this strategy to capitalize a business with more than $100K of retirement funds.The operating business must be a C CorpThe corporation sponsors a 401k retirement planYou can rollover funds from an existing tax-deferred IRA or 401k into the new 401kThe 401(k) then uses an Employee Stock Option Purchase to purchase shares of the parent C corporation.
