Can someone give me some advice I have been watching youtube and seeing these people say they buy 4-6 rentals in couple years.

The Youtube video's look great 

A gentleman by the name of Ben Hedges on youtube is an expert on a lot of this stuff, maybe give him a watch.Also it's important to say that while getting a credit card through a bank with FDIC insurance isn't a requirement, it says a lot about the bank itself and I don't really know of any good banks that don't have it.

I know a lot of people think they can watch YouTube videos, spend time with Real Estate professionals and network, and they can get started investing in Real Estate.

Once you know the reason(s), for the flooding, then you'll be able to figure out a solution.I'd also strongly suggest that you don't re-finish the basement until you've determined the cause of the flooding and fixed the problem (last thing you want is to re-finish the basement, and have it all ruined again by another flood).I'd suggest first watching some videos on youtube on flooding, drainage, groundwater, french drains, sump systems, water catchment systems, etc, just to give you a better understanding on what can cause flooding, and what types of fixes might work.
