My neighbor lives out of state and rents the property.

Makes your property more accessible (at least on the surface).Bad: Has a cost which is not used most of the time.

I have a long term tenant who I inherited when I purchased the property he has always called us whenever there was an issue (A/C not working, Broken window, toilet not working etc) Well last night around 8:30 pm we received a call from him that he called a plumber to remove roots from the sewer line and wants us to pay the bill. 

He can get all three by working in the property management industry.

I have googled alot of information but it is hard to wrap my head around this specific subject. - how can i get a rough estimate on how much the properties will offset?

The property is in great shape near everything you could ask for.

How do you go about obtaining records of properties delinquent on taxes?

Make sure to walk the neighborhood and property before you close on deals 3.

If we have multiple properties, do the properties need to be held under separate LLCs or can they be under 1 LLC? 

We installed an interior French drain system in the basement, because we knew that the neighborhood is prone to water intrusion.
