Need Help!! New to investing

[Cassidy Burns]

Hey Guys,

I am glad to be a part of Bigger Pockets, seems like a great entryway to getting started and becoming more financially free.  I am a real estate agent in the Washington DC/Bethesda, MD areas and am starting to get into the investing side.  I just purchased my first 3 bed 3 bath condo in the city and am currently cash flowing around $550/month.  Feeling pretty good... But I want more.   So I have a few questions:

1.) As a landlord, any advice on how to keep cash flow/security deposit?  Create a new account?  I know you do not want to spend all of the cash flow immediately due to saving for capital expenditures.  

2.)  I have all of this access to great off market deals, in good areas but I don't have all the capital I need to purchase these.  How do I get the finances?  Or if you have investors what is the best way to "write up the deal?"

Any help is great.  Thanks so much and I am looking forward to the future ahead!
