Separately, if I experienced flooding in the past and did major plumbing renovation work to resolve the issue, do I still need to disclose these resolved issues? 

I've done this with my properties because I'm well known in my small town and don't want people to know what I own.LEGAL PROTECTION: By placing your assets in an LLC, you are legally separating them from your personal assets.

@Daniel HymanThanks for the idea but another problem I have with using the government internet is a lot of things on websites don't work because of the firewall and network settings so when I try to apply for the account it just doesn't go to anything.I think if you open another account and keep the funds separate you should be ok, but I'm no lawyer

And an actual lot split which was a SFH on .85 acre now turned into two separate lots, with a duplex on each lot.

It seems like you just really wanted this property so you let your emotions drive your offer.

An LLC when properly formed and administered provides separation and protection of assets that are outside of the LLC from the actions of the LLC.  

The idea is to use this property as an office space, giving me the separation I need from home while providing a place for my assistant to work where I can be more hands-on with them.The business would pay rent for the property, which would cover its expenses.

Much more emotion into the deals. 

The title search would likely happen simultaneously to your own due diligence and the lender's due diligence so it wouldn't really be separate steps.

You do not need separate checking accounts for each property if the ownership is the same.
