Trouble selling 2 of my homes. Flood land, zombie house neighb

[Eric Lefebvre]

I'm selling both of my rental houses in town so I can invest out of state. First...There is a zombie house next door  then a wetland probably 100 ft long and another zombie house past the wetland. So technically 2 zombie houses on each side. The only 2 in the neighborhood. I already lost the first 3 showings due to this. It's a great neighborhood. The other is in a flood area so I need extra insurance and home buyers run away once they hear that. In both situations what can I do to help the buyer not freak out and actually want to acquire the property?  This covid19 is screwing me too becuase showings are shut down for another week or 2. So I put 2 homes on the market and bam. The virus struck. I'm worried about all these low ball offers also if I even get one.

Take a couple ladders and tarps and put them up against the zombie house to look like it is being actively rehabbed.
