When do you know its time to buy?

[Chance Cooper]

So after this deployment I will have some heavy cash set aside. I have managed to do a good job keeping my debt low. I have a truck payment, and two mortages, one mortage is currently renting and Im making $350 a month profit off of it...So really I have my Primary mortgage, and my truck payment.

My plan was to pay off that rental and then receive 100% of the profits every month, minus taxes and insurance. If felt this would give me a better foundation for my rental empire.  But now after reading a lot of the post on BP, I have realized it may be better just to pull 20% for my next property out of the money Ive made off of this deployment and buy another house.

What would you do? Would you continue to save and completely pay the first rental off, or take 20% from your savings and buy another rental and grow your empire?

There is no wrong or right way, I am just interested in your views as it may help me make a better decision. So, please tell me, what would you do in my situation???
