Starting locally with multifamily and house flipping is a solid plan.

From there, it requires the ability to conduct underwriting the highest and best use of a planned project, which requires a pro forma built by the user or acquired from a competent 3rd party. 

I call this dumb debt: Quick note; the deferred sales trust can save a failed 1031 exchange( cost zero to have this option, nor does it take any of the identification property positions) (It's wise to always have a back up plan)More on Dumb debt.

Many other projects have reduced or suspended planned CF distributions and I've also had a few capital calls in which I did participate since the business case still made sense (the MF in Florida had a capital call to finish construction and get through stabilization and it still returned the 32% IRR).I expect almost all of the deals to be OK, just later exits than originally projected.I am very concerned about one project and have already written it off in my head.  

We plan to remove them all to protect from tax increases on our current primary, but I am afraid that now that the other properties won't have homesteads, we may see skyrocketing tax bills and it will eat into already small cash flow from rental income.Does anyone have advice for how to handle this situation other than just increasing rent?

If the tenant has a reasonable explanation and a solid plan on how to recover we will work with them.You are asking the right question: how are you planning to pay double rent next month?

Quote from @Tar-U-Way Bright: Hello Everyone,I'm preparing to purchase my first investment property in the new year, which I plan to house hack.

Talk with the lender and tell them your plan.  

Especially if they plan to buy a more expensive one.

I've decided to stabilize it and pay down the mortgage for a while and reassess in the future what my plan is.
