Appreciate the response, I’ll keep that in mine 

As previous responses stated the the cash flow will depend on your down payment the terms of your financing.

If it gets a great response and the second unit is still vacant (hopefully not!)

@Mario Bellavia Thank you for your response.

They will inform you on what to do next.I'm not sure about FL, but in NC, Section 8 holds the tenants to a very tight list of responsibilities. 

The disappointment was that her response was that it couldn't be done and 'this is the way it's always done'.One of the specific challenges I'm facing is the green light on the financing.  

After this, it`s their responsibly. but again, who will pay this work/storage?

I also suspect he is using the tax's to wiggle out of the deal if you were responsible for the tax's i would pay them pronto so he can't default you.YOu can for sure lawyer up as it may come to that to get the seller to respond.. but again seller may not have the means .. then what  ???

There were also complaints about alleged slow or nonexistent responses to email questions and communications.

If you provide it you are responsible to repair it, the fact that the washer and dryer were there when they moved in would lead me to lean towards a you should provide laundry services answer, however you may want to switch out to coin laundry or submeter the water for the future anyway.
