I have 2 rentals free and clear, what's my next move?

[Logan White]

Three years ago I received a free/clear house on 2 lots and some money from family in my home state (currently active duty USAF). I immediately repaired anything wrong, updated the house and rented it. With the remaining money I purchased an additional small lot and a mobile home for a 2nd rental. After that I purchased 75 acres in the country. The 2 rentals net me around $1200 a month.    My next step is buying the 3br 1ba house neighboring the lot with the trailer. The seller will carry the loan on that one and all other properties are free and clear.

In the end my goal is to retire from the Military and continue investing in rentals. My question for everyone especially the pros is, if you were in my shoes and knowing what you know now, how would you move forward?
