If the landlord is paying any utilities that are based on usage such as water, then I might discuss a rent bump to compensate for the anticipated increase in usage and address that with the lease update adding the person as an occupant. 

You have $606 after tax dollars to spend on the rest of life's expenses, including investing, buying flowers for your significant other, cell phone bill, water/electric/vehicle expense/food/childcare/hair cuts/vacation. 

Typically the standard is 20% especially with your credit. 

It's the visual thing for some people mostly, with such small wall space having it right there in your face isn't ideal. when at all possible, every flip will just get duct work and standard air conditioning. 

Aesthetics won’t be an issue and it will pay dividends in the long run with eliminating landscaping/lawn and water costs.

If not, what happens when neighbor owner isn't maintaining their roof and water leaks are impacting your tenant?  

I recently have a water leak in a house.

They put levels on the pad and check to see if there are any noticeable water entry points.

It has changed a lot with new 2017 deleading standards.

Will I need to pay for sewer, or is this included in the water bill?
