If you don't/won't have WiFi then you should either consider a SimpliSafe system that you can move around from house to house, or some type of Trail cameras like hunters use for identifying game areas.

Play games.

I am new to the game and using the FHA loan has just seemed to be the most common way to house hack (at least in terms of what the resources I have read have said). 

It could take years of sacrifice and saving to get into this game and most people don't want to wait that long.  

I am playing a long game.

Your story proves that being in the game creates opportunities you can’t plan for.

Do you have a particular system or software that’s been a game-changer for you?

For example I know many who are now just lending because they are getting 10-12% short term which is far better than any cap rate on real estate. you do not have the equity upside as you do real estate but its a way to play the short game to see what happens over the next 12-24 months and decide when you want to buy.

Then connect with some hard money lenders (you can find some here on BP as well as some who are typing this right now) and connect with them to understand their product type, what they like to lend on and requirements.Hard money broker is all numbers game of making relationships and helping those that are looking for financing, it starts out slow but if you get with a few good borrowers and lenders it can be pretty decent money to be made.As an example we paid six figures last year to HM brokers. 

After reading so many intros of young, single, eager individuals, I'm hoping I'm not too late to the game!
