As I evaluate this, I figured I'd share my account with my bookkeeper, but then realized that would also give them access to my accounts.Don't get me wrong, I like Baselane so far, but this might be a fatal flaw for me.

Think of the worst case scenarios of what can go wrong and are you ready to handle that.See if you can buy time.

Definitely go the legal route here, don't rent out the basement unless you have the OK from the relevant authorities--it's regulated for a reason (fire safety, carbon monoxide poisoning, etc.) and your insurance will not have your back if something goes wrong.

This is what can go wrong when you have beginners wholesaling who have no training in real estate, no experienced managing broker to go to for advice, no license, no E&O insurance, no knowledge of how to avoid scams, no regulatory body to answer to, no relationships with other quality people in the industry like title companies, lenders, contractors that they can refer to help people, etc.
