After paying mortgage, taxes, insurance, and accounting for vacancy, maintenance, etc. it will be a break-even situation.

I originally think that Florida's insurance is off control, then I found the NC properties' insurance increased 40% from last year and tax will increase also.With current inflation(3%, 30%, or 300%), more and more people can't keep a home in most place although the interests maybe under 4%. 

ITI is the interest, taxes and insurance versus principal taxes and insurance.

You'll want to make sure you have every contactor fills out a W-9 collecting their name, address and tax id. 

Considering the hefty property taxes in my current area, totaling around $9,000 annually, I'm contemplating selling and reinvesting in two properties within the Charlotte area.

The zoning record says it is in an unincorporated tax district. 2) A home in Kennesaw that is also zoned for single family.I see online that there is conflicting info, where in DeKalb county, 3 unrelated people can live together, but Decatur shows 2 unrelated people.

I know the taxes are low.

Quote from @Chidvi Pemula: I avoid smart devices, particularly on short-term rentals.

Also (very important) when STR online portals (Airbnb/VRBO etc) will collect tax and send it to your local govt along with the address for which it was collected.

What should i avoid and which areas?
