People want to get away to a coast, lake, or mountain area, escape from their homes they are locked up in for months, but do it with minimal risk of COVID. 

How do people minimize risk here?

Plus your brokerage "desk fees" or however the brokerage determines agents costs, I know some are very minimal and some seem very high.

You are right - that would be a great way to minimize that risk.

Is there any minimal amount?

I personally don't hit the 70% rule every time, usually because they are larger deals (600k ARV) where there is still a very healthy profit, and we've come to know our process, the area, and what sells which minimizes our risk.  

I have excellent credit (over 800) so I am trying to find the lowest rate with minimal fees. 

And maybe commit to keep reusing their skills for long terms.I do this, especially with profit ranges being minimal in ARV. 

You can use your IRA or your inherited IRA to invest in real estate and you have 10 years before you have to pull it out. so you can distribute money out over those 10 years and potentially minimize the taxes.  

So if you get the home in a place or buy the home in a place where there is minimal maintenance the home could cash flow well.
