Focus on one strategy, practice analyzing deals, and take consistent small steps like attending events and building relationships.

I currently work with investors looking to build their portfolio with single-family, long-term rentals while managing for them on the back end, making is hands-free for the investor to still work their W-2 job and live their everyday lives and spend it with family, hobbies, etc. 

The general idea is that you must acquire an interest in real property you do not already own, and since you already own the subject real property you want to build on, the transaction must be structured so that you are creating an interest in real property you do not already own (in fact, it does not yet exist).

My goal would be to build an investment net with passive income, de-risking the fact that I am the only earner.  

It takes dedicated resources to build out and to do effectively at scale.

With your costs being less you can invest more into the property to build reviews and get bookings. 

Rentals also build equity through tenant payments and appreciation, with profits taxed at lower long-term capital gains rates when sold.

Wholesaling is a great way to get your feet wet and build connections.

Building a cabin in a tourist destination that does not have easy access to gas or electric.So I will need to run electric line anyway and considering installing underground propane tank, is it worth it?

It would be worth quite a bit more now, prices in the area have gone up since the announcement of Micron building down the road.
