I also think it helps that tenants had federal stimulus money and unemployment with the bonus $600.

I just read that Biden's eviction moratorium only applies to properties with federally backed loans.  

We wanted to sell that property within the window of living there 2 of the last five to avoid capital gains, and move that equity into cash reserves and other real estate projects in the Denver Metro area. 

:Detailed Breakdown of My situation:I have saved up enough for a 20% down payment + some reserves to purchase a property.

Typically Single Member LLC activity is reported directly on your individual return for Federal income tax purposes (assuming you haven't made an election to treat the LLC as a C Corporation).

I generally agree with this for people that want to continue growing their capital, and in many ways it is actually helping reduce your risk, since you will go from 2 to 8 units so a single vacancy doesn't effect the portfolio as much.The only caution I can add is make sure when calculating your cash flow, both on the existing properties taking into account your new debt service, and the new properties, that you truly are keeping enough in reserves.

Always have a cash reserve when possible.

Some neighborhoods to consider would be Federal Hill, Locust Point, Fells Point, Hamden, and Canton just to name a few.

Does starting a high-yield savings account for the cash I have for my current downpayment and future cash flow/reserves make sense?

You should have reserves and more reserves as number of properties increases.
