The key is the first loan, I call the "acquisition loan" which needs to provide 100% financing and allow you to buy dated or distressed properties as this is the quickest way to create instant equity (critical component in this strategy). 

@Villy Ellinger To date, I have not seen any category of rental (STR, Commercial lease, multi family) able to trigger Loss of Rent coverage under their insurance policy.Typically, business interruption insurance is triggered by a direct physical loss or damage.

They delayed the process so long, that eventually my closing date had expired and I had to walk away from the deal.

However, I speak from the perspective of a commercial broker, who sells Mobile Home Parks, I am not sure of the outlook of agents in the residential route.  

Seller owes 11k mortgage on mobile home in a park.

Purchase price: $800,000 Cash invested: $300,000 A small mobile home park consisting of two houses, 13 RV spots, 17 Mobile home spaces.

On our move in date, the manager didn't even go into the unit to inspect after the previous tenant moved out nor was any maintenance or finishing done to the place.

For example;https://www.georgiamls.com/424-powers-ferry-rd-se-marietta-ga-30067/87490783 beds, 2 bath all brick ranch, 1400 sq ft built in 1953Interior was dated, had extensive damage and because it was built in the 1950s, I estimated it would need extensive rehab including plumbing and electrical replacement.

If the date of sale is considered to be April 2020, I will not be eligible for the Section 121 exclusion since I haven't lived in the house since 2014.

Great summary, @Anton IvanovTo add some clarifying comments regarding the rules allowing for up to $100k 401k/IRA penalty-free distributions and up to $100k 401k loans:1) You have to qualify (i.e. your health or financial circumstances has been impacted by the virus in one of the enumerated ways)2) Your plan has to allow for such distributions/loans (i.e. employers don't have to allow it)3) The loan must be taken by 9/23/20204) The distribution must be taken by 12/31/20205) For distributions, you can Waive withholding requirement (typically 20% when taken from employer plan)6) For distributions, you may avoid the taxes if you deposit the funds in an eligible retirement plan (which includes anIRA) within "3 years and a day" of the date of the COVID-19 distribution (note: compare to a 60-day rollover).
