By BRRRRing, you can achieve your goal of acquiring four houses with minimal effort and financial strain, allowing you to shift from buying to paying them off.

Ultimately, it’s about weighing the effort and risks of managing this property versus reallocating your capital into assets that align better with your goals.

In my experience, most agents are lazy and don't put in a lot of effort (maybe they just do RE part time). 

It takes more effort and there's more risk involved (therefor more reward), but it just depends on your goals and how you want to get there.As far as focusing on areas with high demand for travel nurses, that's just 1 tenant-type of many in a changing landscape.

That requires you put a lot of time and effort in coming up with a sellable plan to convince them this is the right move. 

I would try and manage it yourself if you have the time and effort. 

Where is vacancy, maintenance/cap ex, asset protection, PM (include it even if self managing as you deserve to be compensated for your efforts), utilities, misc.  

It would be nice if you gave them more than that, because it takes a lot of effort to move a business (online marketing, business cards, etc.).

Leverage magnifies return. 3) The effort involved in adding an ADU is comparable or larger than a rehab associated with a BRRRR.

The ways around that are to build a business around supporting their voucher and inspection program and spending no small amount of effort ensuring they are smoothly servicing your rentals.
