And does his bank accept it? 

The estoppel is a form filled out by the tenant, then confirmed by the Landlord, and then accepted by the Buyer.

I do occasionally post about it on some of the social media sites for travel nurses, such as Travel Nurse Gypsy Housing for example. 

Much better you place the burden on the seller than accept the responsibility.

If Acme Disposal does not accept the items, you must transport them to the landfill.

I agreed to accept 80% under the City of LA program because I thought it would be a somewhat fast payment and it'd be nice to get the tenant caught up.

You can find different strategies on how to find and reach these folks, such as driving for dollars, targeting mailing lists, networking with Realtors and other wholesalers, and having an online presence, plus paid social media ads, etc.

When doing recon at the property before accepting it, we speak to tenants who complain heavily about the property manager.

My background involves social work & non-profit management before getting into real estate.

Also, staging and professional photography can help potential buyers visualize the space better.Lastly, think about local advertising—social media, networking, and maybe hosting an event for local agents could help get more eyes on the property.
