Recommendations on personal finance software for begginer

[Eran G.]

For someone who keeps their life quite tidy and neat, I am afraid to admit that I currently do use any budgeting software to keep track of income and expenses. I currently own one rental property (SFR) and I am in the educational stage of serious real estate investing (meaning I am not out making offers at this time). I know I need to have a better grasp of my finances if I really want to play this game.

Having absolutely no experience in formal accounting (but being smart with money), I am quite overwhelmed with which personal finance software I shoud go with.  There is Quicken (which I have read is for personal finance), there is Quickbooks (which has much more powerful features and is geared for businesses - which I do have one), and there are competing products.  To make things more complicated, both Quicken and Quickbooks have multiple versions (Starter, Delux, Premiere, etc. etc.).  

I wish to start at the beginning with understanding my personal finance picture as well as have the option to later include my investments into the fold.  With those needs and wishes stated - where should I start? An Excel spreadsheet, Quicken, Quickbooks, something else...
