for (Customer__c c: testNewMap.values()){
if (c.Vehicle__c != null) {
cusmaps.put(c.Vehicle__c, c);
}
}
List<Property__c> res=new List<Property__c>();
for(Property__c pro:[select id,Vehicle__c, Latest_Customer__c from Property__c where Vehicle__c in : cusmaps.keySet()]){

res.add(pro);
}
update res;// if you need for insertion purpose apply this – insert res;
