In the current version of MyHome, property ID is generated automatically by WordPress
e.g. property below have ID: 113
WordPress ID is also 113
The only option to make it more flexible is to create new new number field (/wp-admin/ >> MyHome Panel ) and add it to single property manually.
Additionally you can hide default id on the property page:
via this CSS:
.mh-estate__estate-info > ul > li:first-child { display: none!important; }
