proper notice to enter is usually defined by the state as 24 hours notice. some states require 48. that is your starting point. that being said, coming through with a high amount of showings can be considered as disrupting the tenants right to peaceful enjoyment of their home. if you plan on coming through with one or two, you should be ok (legally) to give tenant prior written notice and come in regardless of their objections. if you think it may take multiple showings, you are likely better off to work with the tenant to set up a block of time for an open house. in extreme situations, you can consider offering a gift card to a local restaurant or movie theater to get them out. the tricky part is striking a balance between what is legal, entering with proper notice, and what is fair and reasonable, since the tenant can purposely leave the house an extreme mess to make it harder to re-rent, badmouth you to potential renters, and may even try to refuse entry. how you approach will depend on your relationship with tenant.

This may be resolved by now, just wanted to add that if they pull the "ESA" card (emotional support animal) it sounds like you may be exempt (landlords owning <3 SFH not leased by realtor are exempt). 

I am aware of credit cards but hard money and gap money lenders both require the same thing.
