They have no concept of how to manage time... 

Since you'd be looking to hold this property long term, look at what the property's cash flow and appreciation would potentially be 5-10 years down the road to help inform your decision.All that being said, if you feel confident that you can cover the maintenance, capex, vacancy loss, turn expenses, and leasing costs for a few years while you wait for the cash flow to improve, and you have enough risk tolerance to handle a potentially difficult tenant in the first few months which could lead to zero rent coming in during that transition to getting a new tenant in place, then it sounds like a solid deal to get into with $0 down.Lastly, I'll also caveat all of my statements above by mentioning that this all requires you to self-manage the property. 

I have been a self-managing host for 10 years and ditched my HWs a long long time ago (still have one on my personal home). 

Bonus: You get to stop paying any fees related to the FL LLC.

If you want to be completely certain, then you can dive into the zoning regulations and make sure there isn't a maximum amount of un related individuals living in one residence or specific bans on ADUs without enough lot size.I hope some of this helps!

Now if you have a general person who stops in to do other small tasks or do more property management style tasks (walking through the house to inspect for damages, drop anything off guests may need, change water/HVAC filters etc.)
