Hi Pat: Yes, you are allowed a cat or dog up to 20lbs and there are no age restrictions on this community (Isles at Lagomar) - it's not a HOPA (Housing For Older Persons Act) designated property.
This is a short sale and will, as such, require third-party approval from the lender. There is another, similar unit available next door in the same building and owned by the same owner. The price is also the same ($78,000),
If you need any additional help or information, don't hesitate to let me know.
Best of luck,
