However, you never want to be in an over leverage situation that could result in forcing you to sell at an inopportune time.The way I look at it the difference between what you pay and what return you achieve is profit.

That is always a must, and  then approach every owner the same with the same info and data. 

If the strategy that you're currently using works for you and achieves the result that you're looking to achieve, then there's no need to change strategies. 

I'm not entirely sure what you are trying to achieve. 

What are you wanting to achieve?
