The low interest rate of last 5-10yr is an anomoly if look you back historically. 

Purchase price: $265,000 Cash invested: $60,000 1930’s historic home with a converted garage.

We prefer not to sell the stock for numerous reasons including that share price is historically low right now and due to length of ownership we don't yet have any vested grants that we can take out at capital gains rates.

Historically you've serviced $3000 in credit card debt, now you have $900,000 in debt and zero track record of servicing it (yet).

We're looking to purchase a historic house that has excellent income potential but currently needs moderate rehab work (foundation, flooring, bath remodel), and we're looking for financing options that will allow us to make those updates in addition to the purchase.

Historically speaking (last 60 years) rising rates never had the power to crash a market.

If you are planning to continue in your career, I would continue leveraging your high income to buy properties in historically strong appreciating markets like the parts of LA in which you currently own.

Rates are very low right now historically.

Rates have gone up recently but are still low by historical standards and, in my judgement, will likely keep going up for the forseeable future.
