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;
}
