Hey Mark,Welcome to Bigger Pockets and a warm welcome back to the States!

You need to make sure the basement is 100% dry or you will deal with water and mold problems, destroying your investment.

At the time, I was selling water systems door to door and purchasing property was the furthest thing on my mind.

Being interested in new technology, I decided to test the waters and purchased 1 NFT worth $50.

I was informed that the downstairs unit was flooded about 3 years ago from a water leak and there have been a few other minor water-related issues as well. 

That ensures they stay alive, stay in contact, stay safe and warm, and have the means of getting to job interviews or doing whatever it takes to get back on their feet.

That includes items such as a bigger water meter, work in public space, updating the energy efficiency, fire sprinklers, and so on.

When doing the inspection the tenant said not long ago there was water in the basement up to her ankles but was fixed recently.

They're especially great at putting the fear of God into you that if you don't use a "professional" to do the work, oh, water could get into siding, and cause serious damage, and no, no, no, you don't want that...They also offer the outside trim ("zero-maintenance") wrappers for the windows that you would want a bender brake to make.

Biggest issue to me would be water intrusion/mildew and the accompanying smell.
