DHS has one of the lowest median incomes in the larger So Cal area, consequently it has some of the lowest RE prices. 

Then buy a rental property.Many Americans are sadly being seduced into the lifelong renter mindset without realizing the horrific consequences it could be dooming them to.

As long as the Daughter is making all payments on the loan and paying back any costs to Father, could that father be removed from Title as as  "JOINT TENANTS" (not holding as Tenants in common which is more used)Will there be any tax consequences if the Father is removed from the Joint Tenant title?

I'd rather bet on myself and live with the consequence than throw money out of state and lose most if not all control. 

If you're parents are going go receive any money from that then they will have to take depreciation then on that property and it will appear on their schedule E as well (upon sale they have to recapture any depreciation they took or could have taken so watch out for that).If you go further the route @Corby Goade suggests with a deeding you'll want your accountant to advise on gift tax consequences or use of the one time limitation. 

What tax consequences on each 30k remaining in each of our 1031 exchange.?

A buyer can't just decide not to and then go Rip Van Winkle without any consequences, it's a contract where they agreed to do certain things by certain dates or risk losing their EM, they are not window shopping for bananas. 

I would say the @Kyle Kadish summed it up very nicely; as long as the real estate is being used for investment purposes, type is of no consequence.

We could sell the primary and move to the larger rental but I’m not sure the long term consequences if we move out and want to 1031 that house at some point in the future.

Prop 10 certainly could bring some changes and some unintended consequences as well
