As rightly mentioned by @Kirk_Masden, you may wish to go through the concept of referencing as described in the referred article.
It sounds that you have created Owner-Properties table , which is a kind of bridge table between Owners table and Properties table. You have mentioned that one owner can have many properties and one property can have many owners.
If so, I believe you may refer the sample app “Order Capture” that has a similar bridge table concept implemented.
In the sample app, “Order Details” table is kind of a bridge table between Products table and Orders Table. One order can have multiple products and one product can have multiple orders through this Order details table.
I hope this helps.
