There are some caveats i.e. principle reduction isn't liquid and only a benefit if values don't decrease, things like depreciation are recaptured at sale and you pay some tax then but if you're in a high quality market, buying and holding for the long term, etc it may still make sense to consider below the 8% CoC level if your confident in your numbers and have appropriate reserves.

Don't change your principles and strategy just because the local market won't work, change your market to fit your principles and goals!  

@Anthony Rosa - I'm still in the learning phase and working through deals to define my cash flow objectives.

Your mortgage payment is principle and interest, and should be fairly easy to calculate.  

We’re planning to aggressively pay down principle so we can access our equity quicker and use it for another purchase.

Careful...sometimes there is too much information, and you can spend hours going down rabbit holes or chasing the next shiny object! 

While the CDC Order may prevent eviction of the holdover tenant over his or her objection, the tenant may be more motivated to voluntarily vacate the property due to their liability for double rent."

Though one thing is that hardly any principle gets paid down initially. 

Another very important question is are you looking for cash flow or appreciation as your main objective with your investment and yes there is a difference. 

I found an attorney to be sure I got my principle back.
