I think we are at the beginning of a real estate crash at least as big as 2006-2012.

Other than that, maybe some updated bathrooms or kitchens.I do believe that the rent can be increased to $425 however a $50 a month increase in the midst of a corona virus and possible market crash may not be the best timing so I left the rent at $375 for now.  

Looking to put some into index funds during this market crash.

National rent waivers would crash the real estate market...not an attractive path for the government.

If pricing does not crash, could see a lot of sub2 deals going, but unfortunately I think in markets with an abundance of STR and rentals they will see some decent price declines.

It was in San Diego after the market crash.

I am worried what if the housing market crashes soon.

As @Joseph Cacciapaglia said, there was no money after the 2008 crash and I’m not even talking about the banks.

At 3.75 amortized over 25, thats $1,275 payment that I'll end up getting stuck with because of the crash. 

Banks will have a smaller pool of qualified buyers due to job loss.With people out of work and the market having crashed in the last 6 weeks or so, cash buyers will not have the cash they once had.
