My recommendation is to eliminate all debt prior to investing, and then let some subsidizing be okay with higher leverage amounts(if you're comfortable) for very good properties.

You will have eliminated approximately 85% of the worthless properties that shouldn't be pursued.  

This eliminated nearly all of our profit, a simple mistake we should have caught on the front end.Mistake #4: We assumed the contractor was reasonable and not confrontational--After we fired the contractor, we hired out the items he did not finish, or did sub-par.

Talk of eliminating the 1031 Exchange dates back to the Clinton administration.

Add to that builders and tradesman who don't want to see jobs automated or eliminated and it could be difficult to see alternate contruction. 

But you could JV with an established builder, get the deal done, for less, making more via eliminating margins AND have built a good relation to move forward and do repeat deals with, turning 1 deal done into the 1st deal of many to be done. 

I spoke with their appraiser and he said since SB 9 eliminated residential zoning, he was allowed to use mulit family's as comps for properties with ADUs and JADUs.

I'm generally a pretty optimistic person when it comes to this stuff but I have started keeping more assets liquid and eliminating some of my leverage that's going to reset in the next 2 years because I'm uncomfortable with how things are going lately. 

Can anyone tell me which ones are absolute crap so I can eliminate them right off the bat?

@Braden DownsIf you're this interested in making money, debating investing via ROTH or REI,... and expect to remain diligent in your savings, I judge it very likely that you will soon have an income high enough to phase out or eliminate your ability to contribute to a ROTH.
