It's technically not an ADU if it's the only property on land as it's an accessory dwelling unit to a main unit.

If you currently have a high cash flow income stream in place that allows you to weather the negative cash flow storm from your rental(s) with the intent of holding the property(ies) for appreciation, then it may make sense for you.

Anyone with a little extra money on their hands with the intent of buying real estate may be considered a legitimate lead.

Rent controls will be a real issue if you are planning it as a rental investment which in fact reduce the value of the main house as a rental.

I have 4 long term rentals in my portfolio and I am mainly focusing on investing in single family homes in Traid, NC. 

For me, I wanted to portray my real estate investments as more professional and that was the main reason I switched to using landlord software for rent collections. 

The main reason I would like to start off my career with flipping a few properties is so I can have a quick ROI and I want to do real estate full time as soon as I finish my contract.

My main goal is to invest in real estate in the future, but I want to understand how everything works first.

The main issue with rental basement is water if it has water issue usually it is a simple fix .Clean gutters ,discharge gutter  water away 10" away from foundation, make sure you foundation soil is slopped away from it .If you need to buy soil get a clay mix .Cut back any tree too close to the foundation look at the drip line that's how far the limbs are out from the tree .If all that is done still has water buy a sump pump  carry the water to day light away from foundation 10" to 15" .

Why he is so intent on bashing me, not sure.
