To grow you must at some point in time take your profits and roll them into something bigger and better.

In time your expenses will increase considerably on individual doors and eat up your cash flow.I would be looking to sell now while the SFH market is still high.

I found a duplex to buy but did not have enough cash available to make the purchase in time.

In time and A LOT of practice, when you come across a good deal, you might just be able to snatch it up and wholesale it if you don't have money. 3.

That's what I did for two reasons.1) I wanted to have an intimate knowledge of the process and know how to work my own contracts.

I'm not a naysayer against high leverage at the beginning, but this seems a little premature in timing. 

Learn the market intimately and decide what areas I want to invest in.

I just found this surprise in a duplex I have under contract in the Minneapolis/Saint Paul area.It was updated to Gas at some point in time.

Since you grew up there you have intimate knowledge of the area.

Standard contracts have some language dealing with these issues, but is often too vague, or provides for options.Things I already knew but came up:#1 You have to be able to verify who is living in the property, which means getting leases in time to verify them.
