Currently work as an RN and thats how I heard MTR as a strategy to REI that caters to travel nurses and health professionals.

You can't charge extra pet rent or even a pet deposit because it's legally not considered a pet.

This active income can help me fund my retirement as well as help me get reimbursement for home office and health care premium while lower my tax liability.

My husband left his job to help me in the business this past year and went to work at a dealership as a salesman when my dads health started declining. 

For example, if your driveway only fits two cars, you need to know if tenants plan to bring several vehicles, as this could lead to parking violations and HOA fines.Don’t forget to screen pets, too!

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

I am now strict about the credit score, and not negotiating any of the other terms like decreasing the pet fee or security deposit to accommodate them.  

Depends on their health and any desire they may have to simplify.

I value my health and try to get 7-8 hours of sleep.

You can tackle your scenarios pending what you have in the background working for you (debt, a helpful partner, your health, etc).
