I don't think anyone here would have advice for Brazilian real estate, but maybe I'm wrong.

On the other hand, single-family (typically) provides a tenant pool that can be more manageable and longer leases, and I am assuming maintenance and capex could be on a smaller scale, but I could be wrong on that. 

Remember that you can only get one home equity loan per year, you can only have one home equity loan on your home, and you cannot convert your home equity loan into a different type of loan, so choosing the wrong loan can be an expensive mistake that you cannot quickly fix.Time Factors: If you need money quickly, don’t forget the schedule for closing a home equity loan, and make sure you will have time to complete the process, close on the loan, and wait through the cooling off period before you have access to the money.

Don't get me wrong here, we still want you to be 100% ethical with what you are doing, but once you fulfill your obligation, it's your right to move.3.

WRONG!

In my opinion, talking about A, B, C, or D "properties" is really focusing on the wrong thing - it's all about the tenants.

Please correct me if I am wrong.

Again, wrong program, but 60% isn’t a number I have ever heard. 

You should be looking to prove it wrong, not prove it right.

There are no wrong things to do except doing nothing.
