Question: Possessive-S/apostrophe in a list, including the first and second person
Answer: If there is one house it is clear in any form, but if there are several houses, as you point out, then it can be ambiguous. "John, Mary, and my houses" would be different than "John's, Mary's, and my houses."

That being said, "Our houses are all on Oak Street," tells us little about ownership. I get that you are not trying to avoid the rule, but to avoid ambiguity, which is the reason for rules, we need to provide additional information.
