Why not optimize to helping folks find those handful of forums of interest vs further subdividing an already thin attention pie?

There are many small restaurants that won't go back to seating because it does not make financial sense to hire back people to support a less than optimal seating requirement.

I guess my next question is, for Facebook ads in particular, what, demographics, income, and interests will help optimize the results for each, or any, of the targeted audiences?

If you're like me, I really enjoy optimizing in a specific niche. 

They are neither lawyers nor CPA but they have a network of lawyers and tax preparers that will help in optimizing what you can keep. 

I personally try to optimize dollars per door.

My goal is maybe not to leave my job but optimize and systematize so I work on the things I want to and on things that make my return on investment the highest.

Especially to optimize RE returns via value adds, BRRRR, etc. is not passive.  

You are always going to be capped by your DTI so as long as you can meet the local lender rules you should be able to at least find something - might not always be the most optimal and may include loans such as 5-yr balloons etc.

You're not in a bad position, you just need to optimize a little.First, you are letting a guy live at your house for under market AND you're paying utility AND you're paying for gardening work.
