BiggerPockets is working on a piece that will share all relief programs that might be available to Americans (disaster relief, financial relief, unemployment, medical, etc).

You need to have written policy in how you deal with tenants and apply that policy across the board.If you allow pets under a certain weight, they have to be allowed across the board.If you have a policy that all tenants must make 3 times the rent, then all tenants must meet that.And if you have a policy about waiving late fees, or reducing rent, or waiving one month of rent, whatever it is, you really need to apply to all.When landlords get into case by case basis with a different rule or decision for every tenant, that's when you set yourself up for a fair housing violation.   

That helped reduce my DTI.

This will greatly reduce the need for office space.

The economy goes through a recession can you handle vacancy or reduced rent for a time being.  

Right now the only goal is to buy time and flatten the curve to let our medical system ramp up and prepare.If it's a good deal, take advanatage of the low interest rates and go right ahead.

All of this to reduce exposure and will sanitize all for knobs I touch after they leave. 

Looking likely that many lenders are going to offer Mortgage Forbearance such as reducing payments for a few months or suspending payments for a few months.
