Bryce,
I think you are in an excellent position.
You're cash flowing
You own the properties
You owe nothing but insurance and taxes
The market can bust away, who cares, you own them.
The rent market can drop, assuming you will still be able to hold insurance and taxes, you should be fine.
You own them......to me this is a safety net a lot of people don't have starting out. They are taught to leverage, leverage leverage......and don't understand the risk.
In my opinion, you are very close to being able to leverage safely with less risk.
One thing you can do (keep your partner out of this transaction) is take the three deeds you have, find a local bank willing to work with you and leverage the deeds into a line of credit.
Chances are it will be interest only loan, but you will have cash available when needed to purchase additional properties or for emergencies. Be sure the net rental income covers any loans you have until you can pay back in full (another deed in hand) or you can refinance to hold itself.
Now, again, this is my opinion and I am sure I will get bashed for it but I like a good safety net before plunging in deeper waters and leverage too much.
