Check the forum for Events & Meetups and see if they have any in your area.

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

Definitely recommend checking out local REI meetups in Boston now and Chicago later—tons of value in connecting with local investors.

And what if the one person you didn't check has a criminal background, has collections, and more?

Here are a few suggestions on how you can maximize the wealth of information available: Check out the blogs and podcasts, or take advantage of the search feature (magnifying glass).

You can simply request a separate check for the $100 increase to bring the total deposit in line with the new rent amount.
