On these sites I would both look at 1 bedroom apartments and individuals looking for roommates/renting by the room.

Once you have a team of trusted individuals in these 4 roles you'll be ready to invest knowing you are in good hands!

I asked me to add my spouse to the plan but they say she has to open another individual 401k.

Theirs lots of money out there and there figured out this vertical is a solid place to put it .We just noticed a company that took a commercial property public in NY.They specialize in crowd sourcing funds and place theme is our space with realizable returns Ahhh change .It will all be about keeping up and educating our investors on how they can/should compete as we see more and more of this .

Conforming loans backed by Fannie/Freddie are only made to individuals and not business's so anything outside of this would be a commercial or private loan.

I am looking to buy and house hack my first home (STR/rent individual rooms in the house).

The competency of the property manager is far greater than whether he/she lives on site.

In addition to that, I don't even think you can own an STR in an LLC as permits are only issued to individual owners. 

You can also have individual subs do their own drawings. 

It is probably very individual what will trigger you to take action, but motivation, consistent learning and perseverance will eventually bring you where you want to be.
