seasoned rookie questions

[Dan Oconnell]

Hello All, 

My name is Dan the first home I bought was a duplex and I am looking to grow my business. My wife and small children have moved into another home and are looking to make some more investments after being able to save for a 20% down payment. 

My concern is on the financial strategy part. I am not putting money aside for maintenance, I am not making extra payments on principal. I am just wondering if there are some veterans out that that could offer some advise. 

Thanks for the time. 

Dan O.
