These tenants are still employed to the best of my knowledge, aren't impacted medically due to COVID-19 and combine for $250K a year in income. 

Are there any negative impacts come tax time for selling so quickly?

@Milind Pawar Those improvements add to your basis but do not impact the 1031 reinvestment requirements at all.  

Me thinks you need to:a - Look for deals in different markets or using different strategies if deals are falling through,b - Use alternative forms of financing (not cash), if loans are freezing,c - Hang out with different people, if you're surrounded by skepticism, d - ...and look for long term budget corrections, so you can be prepared for something like this (not the source but the impact of this temporary situation) in the future...should it happen again.

It's hard in this climate, though, when we just don't yet know what we're dealing with regarding the impact of COVID on multifamily and rental assumptions (to echo @Charles Carillo).I laid out some of my COVID recession underwriting assumptions here.I think we're in the phase where most people have moved to the sidelines, especially sellers.

The end I have to say, the industry has been pretty fortunate to be able to continue with minimal impact.

If a tenant states they have been financially impacted (usually as a result of lay off or reduced hours) here's what we do: 1.

If they only offer Basic coverage, be aware water and theft claims are excluded, and some may exclude Vandelism.3) Loss of Rents equal to 12 months of incomeThis is not a complete list, but are generally the most impactful at the time of a claim.Lastly, most investors don't take Personal Property or Water Sewer Back up. 

I am basically wondering if it is worth trying to take advantage of selling while the market is hot, and assuming the market will be more buyer friendly in the coming months with the impact of COVID taking a further toll.

While I don't dispute the claims and do think there is real long term impact to the numbers, a lot of those claims come from bartenders and waiters.
