How Many HABTM relationships in cakephp is too many?

I'm struggling with deciding how many HABTM relationships I really need in my cakephp app. I guess I don't quite get what "has" truly means. I don't want to have more HABTM tables than necessary. Here's what I have in my database:

Users
Properties
Leases
Payments
Repairs

user HABTM properties, user HABTM leases, user HABTM users, user HABTM repairs, property hasMany repairs, property hasMany leases, lease hasMany repairs.

Also, I have two aliases for my users model (manager an开发者_Python百科d tenant). This is one of the reasons I ended up with so many HABTM relationships, but I'm not sure it's necessary.

Do I have too many user HABTM relationships? Would it be better to just have cake recurse through my models?

Thanks!

This is a rather subjective question. That is to say one only you can decide as you know your code. The best thing to do is ask yourself if the following is strictly true: X really has and belongs to many Y?

For example, does User really have many Payment? Or does User have a Lease and the Lease has Payments? Same with Repairs and Properties.

As far as CakePHP having too many, I wouldn't worry about that. Setting the recursive property on your find(), using Containable, or un/bindModel() will also help limit when all these relationships are used.
