I’m planning to buy another small multi-family property with 5 or fewer doors.

Is it anything to do with having fewer than say 5 comps?

I would look at an existing asset with fewer variables and a more predictable return.

If it is then it can’t be more than 35 Lbs fully grown and no dangerous breed animal even if it is a service animal (my insurance won’t allow dangerous breed animals).No evictions , ever.No felonies, ever.I have had outstanding results with this method here in the East Bay and in Cleveland with this method and I still have more candidates than I know what to do with, even with that criteria.Do what I do and set the criteria as above

The big issue here is that, even if you are completely in the right, and your property was in no danger of actually being stolen, it could create a real headache for you at a really inconvenient time. 

What's the potential danger if I do this?

I had another town admin in a different small city tell me as long as it was fewer than five adults, go right ahead.

Buy A and B properties for more appreciation and higher quality tenants with fewer problems. 4.

This is the danger of starting a business after watching 3 youtube videos lol.

In general, you'll have more income from more units that are smaller, than fewer units that are larger.
