FHA has been the go to for investors that want to house hack forever. 

The deal was taking forever, and multiple balls were dropped in the process of trying to get to the closing table.

You can't leverage a HELOC forever.

Takes FOREVER to set up but once you set that part up, it does the work FOR you as long as you continue to work the system and update your leads.

You need blue collar 58+ year olds that have owned forever, especially if you want good seller-financing. 

You can not for ever be scrambling to get leads.

We sacrifice today by living in a smaller unit, but that isn't forever.

Obviously, it won't be like this forever, but I don't think anyone really knows when "normalcy" will return.

People that have done this forever like myself and @Brian Gibbons   (the guy that me into this whole RE mess) just do our thing and don't think much about it, but reading your post I can obviously tell your head is spinning. 

Most people won't want to house hack forever, but if the numbers make sense, you can move out, lease your unit and hold onto the property with great financing in place, or sell if the market makes sense and roll the proceeds into another property(ies).While I never house hacked myself, if I I knew what I know now back in my early 20s, I would have done this straight out of college in lieu of renting for the first 5 years and would be a lot wealthier as a result...Good luck with whichever strategy you choose!
